Load holding valves from Valvole America are available in a very wide range of cartridges or assembled into valve blocks. They secure the last commanded position of an actuator by preventing fluid from escaping work chambers, with “zero” leakage. They ensure low leakage when closed, with less than 5 drops/min when the valve closed with […]
Error prevention at the source: Proportional valves with on-board electronics
On-board electronics (OBE) is the direct and best way to correct nonlinear behavior of a valve, according to officials at Argo-Hytos, Zug, Switzerland. Direct-acting proportional control valves with integrated digital OBE allows fine control of valve spool position and movement. Incorporating a sensor and electronics into the valve body enables a control loop within the […]
Kraft Fluid Systems now offering extended Danfoss PVG line
Kraft Fluid Systems Inc., which represents Danfoss Power Solutions products in 12 states in the Midwest U.S., has announced an expanded Danfoss PVG 128 and PVG 256 product line and build center. Danfoss Power Solutions has added two high-flow proportional valves to its PVG portfolio—PVG 128 and PVG 256, expanding its range of low to […]
Directional valve offers best of both worlds
The new DPX-HS hydraulic directional valves from Walvoil, Reggio Emilia, Italy, are designed specifically for mini and midi excavator applications. Today, these types of machines typically rely on one of two possible hydraulic control techniques. One uses load-sensing valves in combination with a load-sensing pump to provide precise control with calibrated and independent speed for […]
FPTC Hot Technologies: Ductile iron for manifolds and high-strength materials
Dura-Bar will be showcasing its series ductile iron for manifold applications and its new Solution Strengthened Ductile Iron at this year’s Fluid Power Technology Conference at the Milwaukee School of Engineering. Visitors can see this and other Dura-Bar technologies at booth 203 at the FPTC May 15-16. Better under pressure: Dura-Bar’s ductile iron for manifold applications Pressure ratings […]
HIC custom manifold eliminates leaks
Sourcing one-piece Hydraulic Integrated Circuit (HIC) Custom Manifold solutions from Daman Products helped a machine builder eliminate 39 leak points and reduce labor hours, number of components, and over-all costs by 11%. Several years ago, Daman had a project where this machine builder specified standard components for a manifold consisting of six-station D05H manifolds, three-station […]
Danfoss Power Solutions extends PVG portfolio with high-flow proportional valves
Danfoss Power Solutions has added two high-flow proportional valves to its PVG portfolio, expanding its range of low- to high-flow capabilities for OEM customers with demanding applications. The PVG 128 and PVG 256 valves are designed to easily integrate with the existing line of Danfoss high-performance proportional valves — PVG 16 and PVG 32 — […]
Kraft Fluid Systems expands mobile hydraulic controls and valve product line offerings
Kraft Fluid Systems Inc. has added Danfoss Power Solutions Plus+1 controls and software to its ever-growing product line in Wisconsin. Additionally, Kraft has added Comatrol cartridge valve products to its emerging Wisconsin offering. Danfoss Plus+1 modular hardware and the user-friendly Plus+1 GUIDE programming environment enable Kraft to seamlessly integrate microcontrollers, displays, joysticks, sensors, and Plus+1 […]
Doering Company’s redesigned manual cartridge valve now includes a zero-leak option
Doering Co. has redesigned its manual cartridge valve to include extremely low- and zero-leak options. The company’s zero-leak technology is integrated in the Doering valve used for manual fire suppression in the International Space Station and was specifically engineered to hold pressure for 15 years. The demand for Doering’s redesigned manual cartridge valves has grown […]
Are hydraulic sequence valves dead?
By Josh Cosford A sequence valve is a pressure valve designed to open when its set pressure is reached, providing a path of flow alternate and sequential to the primary circuit. In some ways, a sequence valve is a directional valve, allowing flow to occur. However, it’s just a relief valve with some added features. […]
