SFC Koenig, a Unit of IDEX Corp., and supplier of sealing and flow control components, is pleased to announce that its Chinese branch has moved into a new facility. The larger location allows for increased integration with IDEX China while also providing an expanded manufacturing space to support growth. One of four main global facilities, […]
Screw-in cartridge valves optimize hydraulics
As mobile-hydraulics engineers constantly aim to pack more capabilities into less space, custom screw-in cartridge manifolds can be an excellent option in many applications, according to officials at Cross Co., Greensboro, N.C. The products can address many needs of the machine builder, including small package size, design flexibility, and simplified plumbing and routing. And they […]
Adjustable pressure control valves for regulating hydraulic pressure
Balanced piston relief valve is designed for use in applications requiring an adjustable regulating valve to limit the pressure in a hydraulic circuit to a predetermined maximum. The relief valve consists of a control poppet and main spool which provides low pressure differential and quiet operation. Pressure can be adjusted by loosening a jam nut […]
New retrofit option for hydraulic crane controls
Hetronic’s MEC-HL C MOD kit is an electromechanical radio control modification kit for after-market hydraulic crane applications. The MEC-HL C radio remote control kit includes proportional actuators, remote control radio receiver and a transmitter. According to company officials, it comes at a low per-unit cost with a fast ROI while increasing efficiency and safety for […]
What are flow control valves?
In the collection of hydraulic valve components, flow control valves are any device manufactured for the purpose of modifying the rate of fluid flow in a portion of a hydraulic circuit. Flow variability occurs through the adjustment of the effective orifice size inside the valve, and this is achieved through various techniques based upon the […]
How do relief valves work?
By Josh Cosford, Contributing Editor It seems like a question with an easy answer, but you’d be surprised how often people ask, “how do relief valves work?” We in the fluid power industry take our knowledge for granted, but each and every one of us was at some point ignorant of literally every hydraulic component […]
Valve technology for enhanced control
Innovative application-specific valve concepts are one of the most important requirements for boosting productivity in mobile hydraulic applications, according to the engineers at Bucher Hydraulics, Remscheid, Germany. The company’s new modular SC12 proportional directional valve system, for example, offers responsive control behavior and low operating costs with consistently high machine availability. At the same time, […]
Progressive versus linear spools in Danfoss PVG mobile proportional valves
Contributed by Buck Schmitt, CFPS, Territory Manager – Eastern PA and Mid-Atlantic, Kraft Fluid Systems When designing hydraulic systems for mobile machinery, there are a variety of requirements that range from basic setup functions to extremely precise maneuvers. Let’s examine the more precise and critical functions. There are several ways to approach hydraulic system challenges. […]
What is a relief valve?
A relief valve is a device used to limit pressure in one or more locations in a hydraulic circuit. A relief valve uses a spool or poppet engaged to the closed position by a spring. A spool is a cylindrical piece of machined steel that slides within a machined body. A poppet is a flat […]
Bosch Rexroth’s Subsea Valve Actuator receives award of merit
Bosch Rexroth’s new Subsea Valve Actuator (SVA) received the Award of Merit as one of five finalists in the 2019 Woelfel Best Mechanical Engineering Achievement Award. This award was presented at the Offshore Technology Conference in Houston on May 6, 2019 by the American Society of Mechanical Engineers (ASME). The SVA was recognized as a […]
