Hengli HVSP load-sensing proportional control valve now with CAN-Bus pilot control module
Hengli offers HVSP proportional valves with integrated, intelligent electronics providing full integration into the bus network of mobile machinery with IP68 protection. The internal closed-loop position design of the HVSP valve achieves spool position accuracy levels nearing the performance of a servovalve. This is accomplished by continuously comparing the set- point of a remote-control device […]
What makes a quality hydraulic component?
If you’ve been around the hydraulic world for a while, you’ll have noticed there is a price discrepancy between various component manufacturers. Whether there is a correlation between price and quality is a discussion unto itself, but regardless, you can’t argue the price range is vast. Let’s assume for this missive that higher priced components […]
What is electronic control in fluid power?
Hydraulic valves operate most commonly in one of three ways; mechanical/manual control, pilot control or electric control. Mechanical control involves something physical pushing on the valve, such as with a roller or cam, which itself shifts the spool or poppet. Manual control was long the king of valve control, especially with mobile hydraulics; they’re inexpensive […]
The digital logic valve
Sun Hydraulics Corporation has launched the new solenoid-operated Digital Logic Valve. The DLV paves the way for smaller, highly reliable solutions in demanding mobile applications where size, weight, speed, and power matter and in industrial applications where an incredibly fast valve can help reduce machine cycle times. The first product introduced in the DLV family, […]
Pilot systems for mining shovels: Large motions begin with tiny valves
Pilot systems used in mining equipment showcase the brute force of hydraulics, as well as the precise control. By: Carl Dyke, Contributing Editor I have been in the mining pits. It can be a rough and dusty environment. Two million pound, 5,000-hp shovels quickly and gracefully load 4,000-hp haul trucks that drive off weighing over […]
The Dynamic Machine Control approach to building smarter machines
It’s no secret that OEMs are looking to build more “intelligence” into mobile and industrial machines. The goal is to make the equipment they sell more productive and efficient, safer, and easier to operate and maintain. With that in mind, power-management company Eaton recently introduced its Dynamic Machine Control approach to designing smarter machines. According […]
Bucher Hydraulics develops non-return valves with 50% higher flow
Global competition and increasing cost pressures have raised expectations for every aspect of hydraulic systems. According to officials at Bucher Hydraulics, that’s why it pays to review even the smallest elements of a circuit, such as non-return valves. These valves must work continuously and reliably with long lives, combine a compact design with high performance […]
Where are manifolds used?
Manifolds are used in my many fluid power applications, depending upon the application. Manifolds are used in hydraulics as well as pneumatics, and can be used to mount valves or to consolidate plumbing. When used for mounting valves, they are the interface between the valves and the ports to be plumbed into. With industrial style […]
Kawasaki launched new pumps, motors and valves at Bauma
Kawasaki Precision Machinery is helping manufacturers improve efficiency and cost savings, with the launch of a new range of pumps, motors and control valves at Bauma last month. The new products build on the company’s 20 plus years’ experience in hydraulic systems for excavators and signify its move to a total systems supplier for all […]
