D*1FP servo valves enhance large hydraulic systems

Parker Hannifin has brought out the D*1FP range of pilot-operated servo proportional valves.

These are based on the company's direct-operated DFplus hydraulics control valve, which features Parker's Voice Coil Drive (VCD) technology.

The control behaviour of the Parker Hannifin D*1FP series valves ensures high stability in operation and easy, time-saving installation and set-up.

The VCD is based on the same principle used to vibrate loudspeaker diaphragms.
Parker is using it to control the high forces within hydraulic valves.
By producing dynamics on a par with modern servo valves, the VCD technology results in a much simpler valve structure.
The new pilot-operated D*1FP series has transferred the advantages of the VCD to larger frame sizes and higher flow-rate valves.
The high dynamics and precision of each new pilot valve deliver optimum control of the main spool, resulting in servo-class performance from the complete valve.
The control behaviour of the valves ensures high stability in operation and easy, time-saving installation and set-up.
Whether in the direct or pilot-operated valves, the VCD technology offers the same benefits of robust design and long life.
A new safety concept with the pilot valve can also reduce the need for additional shut-off valves in hydraulics systems.
It ensures the main stage is hydraulically balanced at power down and the main spool is in a safe position.
The D*1FP range is available in four sizes: NG10 (CETOP05), NG16 (CETOP07), NG25 (CETOP08) and NG32 (CETOP10).
With flow rates of up to 3000 litres a minute, the valves bring the advantages of VCD technology to almost any size of hydraulics system and are supported around the world by Parker's global network of manufacturing, sales and customer-support centres.

Australian Brake Controls’ air/hydraulic brakes keep tractors and trailers controlled

A CONTRACTOR from Mel-Ray Industries has installed a dual-line air/hydraulic braking system from Australian Brake Controls in his tractors and trailers.

According to Ray Galdes, towing a heavy trailer around worksites can be a potentially hazardous, high maintenance undertaking.

Trucks, tractors and specialized machinery can be subjected to loads that will place unusual stresses on standard components, including high demands on braking systems in situations where operators need to selectively and powerfully apply stopping and holding power.

Examples include going down a one-in-four slope with a 90-degree turn at the bottom. Gravity will see the trailer trying to push straight ahead, off the road. Galdes says he helped increase the responsiveness and control over the vehicles with the Australian Brake Controls system.

His latest system enables the driver to simultaneously control both the tractor’s hydraulic brakes and trailer’s air brakes from the same brake pedal. The operator can also operate the trailer brakes separately using an in-cab hand control.

Galdes says air brakes are the most effective, as other types of brakes get burned out quickly on slopes.

Australian Brake Controls engineered a system which incorporates a tractor-mounted half horsepower electric compressor feeding a nine litre pneumatic holding tank linked by airlines to the trailer brakes.

This pneumatic system is synchronized with the tractor’s hydraulic system via a reaction valve that automatically senses the amount of pressure being applied to the hydraulic system and turns this into an air signal for the trailer’s air system when the brakes are applied.

Hydraulic fracing dominates ExxonMobil-XTO merger hearing

A congressional hearing that ostensibly was supposed to consider a proposed merger’s market impacts quickly became a forum for debating whether to federally regulate hydraulic fracturing.

Chairman Edward J. Markey (D-Mass.) convened the Jan. 20 hearing of the House Energy and Commerce Committee’s Energy and Environment Subcommittee to examine energy market impacts of ExxonMobil Corp.’s proposed $41 billion purchase of XTO Energy Corp. “This merger heralds a fundamental long-term shift in US energy markets, and one that deserves our close attention,” he said in his opening statement.

But the discussion quickly turned to hydraulic fracing because the proposed combination’s agreement includes a termination provision if Congress enacts legislation making hydraulic fracing too costly and uneconomic.

“This country has a propensity to regulate. We need to protect our shareholders,” ExxonMobil Chief Executive Officer Rex W. Tillerson told the subcommittee.

ExxonMobil wants to acquire the Fort Worth, Tex., independent because XTO’s US unconventional gas resource base and technical expertise would go well with the major’s global reach, research and development capabilities, and financial capacity, Tillerson said.

“The development of our combined resources will create the opportunity for more jobs and investment in the production of natural gas across many parts of the United States,” Tillerson said. “It will support our nation’s economic recovery, strengthen [its] energy security, and help meet [its] environmental goals.”

Focus on gas
Bob R. Simpson, XTO chairman and founder, said the company’s management decided soon after it started to focus not only on gas, but also on long-lived, high-producing reserves. That led it to tight shale gas, where it eventually became an industry leader, he indicated.

“In reviewing our future path, we realized that we needed to look at options to take what we have achieved and bring it to a new level,” he testified. “We recognized that the opportunities before us could best reach their potential if we could find an organization that could bring additional scale, technology, and financial capacity to the work we have been doing. We found that organization in ExxonMobil.”

Markey suggested that the proposed merger has positive aspects, including the signal that another multinational oil company is willing to invest in developing unconventional US gas resources. But he also said that Congress wants to make certain those resources are developed safely, which is why it asked the US Environmental Protection Agency to study hydraulic fracing’s operating record.

Republicans on the subcommittee said the technology is safe. “It is well known that gas will play a more prominent role in a carbon-restrained world,” said ranking minority member Fred Upton (R-Mich.). “In fact, the success of any climate-change policy will need to rely heavily on gas. Yet some members of Congress are seeking policies that would take a majority of our domestic gas off the table.”

Several Democrats said the process uses toxic substances that would create serious problems if they entered drinking water supplies. Rep. Diana DeGette (D-Colo.), who is not a member of this subcommittee, was allowed to participate because she introduced a bill last year to federally regulate hydraulic fracing under the Safe Drinking Water Act.

“I support hydraulic fracturing,” she said. “My bill would not make it illegal or impractical. It simply would require disclosure of ingredients in an emergency situation while protecting proprietary information.”

Fluid confined
Tillerson and Simpson both said they would not have a problem as producers disclosing ingredients in hydraulic fracing fluid, which is primarily water. They also pointed out that the process occurs several hundred feet below drinking water supplies, and that concrete casing keeps hydrofrac fluid confined while it’s pumped below the surface.

States already regulate hydraulic fracing aggressively, they continued. DeGette immediately challenged that idea, noting that only four states have regulations that specifically deal with the process. The executives responded that several others have water-management regulations that serve similar purposes.

They also contended that federally regulating hydraulic fracing simply would add another layer to a process that states already regulate well. Restricting its use would harm conventional production too, Tillerson added. “A lot of conventional wells use hydraulic fracturing to make production commercial,” he said.

When DeGette asked them how much they think having to comply with SDWA regulations in using hydraulic fracing would cost their companies, the ExxonMobil and XTO executives said they did not know. “Much of it would depend on how EPA decided to implement its regulation,” Tillerson told her. “I don’t know what would be in it, and neither do you.”

Markey concluded the hearing by stating, “There is no secret plot on this side of the aisle to ban hydraulic fracturing.” But when he was asked by reporters afterward if he planned to schedule DeGette’s bill for markup, the subcommittee chairman replied, “I’m going to have to have further discussions with her on it before I decide.”

Away in a manger - or a hydraulic shop

Eight years ago, I set up a CNN e-mail alert for "Osama Bin Laden." It was to alert me when he'd been caught or killed, you see.

View LargerDue to the lack of suitable Christmas tree specimens in Afghanistan, B Co 603rd ASB had to make do with what they had: Hydraulic line, a printer and goodies/decorations from home. (courtesy Staff Sgt. Paul Ramus)

  The info in the forwarded articles is always very mundane, and I feel stupid whenever I receive one. Still, I haven't canceled them.
I keep receiving them for sentimental reasons, I guess, to remind me of a time when such dramatically positive developments seemed possible - redemptive even.
Meanwhile, the war in Afghanistan continues, and may have another eight years on the way on top of the eight we've already seen.
I have a child who is eleven. The war's been going on since she was three. She'll likely be in college before it's over.
I'm lucky, though. I can't imagine what it must be like to leave your young children behind while you go off on yet another tour of duty.
Frankly, I'm not sure I'd be able to go through with it. I'm glad I've never had to test that theory.
A couple of years after 9/11, when the Iraq war started, I spent a lot of time feeling sorry for American soldiers on the basis that they and their families were being abused and misused by their elected leaders.
I still feel that way to an extent, but I've long since stopped feeling sorry for them - for the simple reason that they don't feel at all sorry for themselves.
The servicepeople I know, and almost certainly the ones you know as well, don't consider themselves particularly unfortunate. Sure, they gripe about bureaucracy and politicians and regulations, as soldiers the world over have since the beginning of standing armies.
But they continue doing what they want to do, living the lives they've chosen to live, proudly, patiently, and largely without regret.
So when I relay to you the accompanying photo of a makeshift Christmas tree in a hydraulic shop on a U.S. base in largely treeless Afghanistan - reprinted with permission from my friends in the Ramus family - it's not to make you feel sorry for anyone or have pity for anyone, and it's certainly not to incite any particular political opinion either way.
It's there to reinforce the notion that Christmas is what we make of it, and happens wherever it is celebrated. Like that original scene in a manger in the Holy Land, it needs no fancy trappings and has no minimum requirements other than a belief in the possibility of redemption.
