Interface. Pressure and flow rating up to 5000 PSI and 130 GPM, we have the products to meet your requirements. Engineering Essentials: Pressure-Control Valves. Low pressure, high pressure and vacuum proportional pressure control … AMCA specialises in the engineering of client-specific proportional control valves. Flow Rate4 l/min. Our pneumatic proportional flow control valves handle flow conditions from less than 1 liter per minute (LPM) up to 400 LPM. They work well for applications such as press systems, molding machines, and traditional servo markets like flight simulators and airframe testing. They can control pressures between vacuum up to 16 bar. The AVENTICS ED07 E/P delivers a proportional pneumatic pressure to an analog signal. Learn more about Eaton Vickers proportional pressure control valve with integrated electronics operating data, valve performance, and installation in this technical sheet (PDF 161 KB, 11/7/2000) Eaton Vickers electronic accessories for proportional valves with associated power amplifiers. Pressure-control valves are found in virtually every hydraulic system, and they assist in a variety of functions, from keeping system pressures safely below a desired upper limit to maintaining a set pressure in part of a circuit. Get smooth, accurate control of your pressure and flow applications with our range of proportional screw-in cartridge (SiCV) valves. HYDAC proportional pressure reducing valves are continuously adjustable valves which control the pressure of the consumer depending on the electrical current. HYDAC proportional valves are electronically actuated valves for which the output value - pressure or flow - is changed at the same ratio as the inlet value. A hydraulic system can only function - as per requirements - by using valves. Operating Pressure315 bar. Size. Proportional Pressure Control Valve EPDRD3-05. TypeEPDRD3-05. Proportion-Air, Inc. manufactures electronic air pressure regulators and air flow control valves. 2) in such a way that, during a steady pressure rise in control chamber 34, i.e. When applied in combination with Eaton logic element valves and other SiCV in a custom manifold assembly, Eaton proportional valves create an … Proportional Valves. Mounting Style. An additional function is the maximum pressure protection. Reset. In direct-acting proportional control valves, a direct-acting proportional coil solenoid is used, which acts directly on a piston or spool to adjust valve open or closed positions, based on varying voltage across the coil. The Kelly Proportional Valve Range. Operating Pressure250 bar. Thus, you should always look for the correct type of hydraulic valve to serve your intended purpose. Our valves cover the complete performance range from standard up to maximum dynamics. The Thomas modular system offers our customers tremendous benefits, as it allows a customized, cost-efficient combination of these compact valves according to … The compact 3-way proportional pressure control valve EPDRS3 size 10, is a pilot operated valve in spool design which reduces an inlet pressure to a lower consumer pressure. 2,600 proportional pressure flow control valve products are offered for sale by suppliers on Alibaba.com, of which valves accounts for 6%, hydraulic parts accounts for 1%.
