Proportional solenoid valves for pressure and flow control - 2

This section gives basic specifications for the complete line of Vicker's screw-in proportional control valves. Its purpose is to provide a quick, convenient reference tool when choosing proportional valves or when designing a system using these components. The EPV10 has several outstanding performance features which give it a unique position in the screw-in cartridge valve market. flow gain linearity, flow force pressure compensation characteristics above 20 bar (300 psi) and low internal leakage. The EPV16 is a proportionally controlled two-way poppet type valve. The main poppet amplifies...

Read this page before using any of the products/ information in this catalog. A Warning When using the "Screw Type" override, care must be taken to return the override back to its neutral position before activating the valve. Failure to take this precaution may result in personal injury or damage to the machine. Warning Aluminum housings can be used for pressures up to 210 bar (3000 psi). Steel housings must be used for operating pressures above 210 bar (3000 psi). Eaton Hydraulic Screw-in Cartridge Valves (SiCV) E-VLSC-MC001-E7 — November 2019 www.eaton.com

PFR21H - Proportional valve Proportional bi-directional poppet, flow control valve Up to 18L/min (5 USgmp) • 210 bar (3000 psi) Operation In the de-energised position the valve is blocked in both directions. As the current to the coil is increased the valve opens proportionally. There is also an element of compensation as the pressure difference across the valve increases. See performance graphs. Performance data Ratings and specifications Performance data is typical with fluid at 32 cSt (150 SSU) Max inlet pressure Max regulated flow at rated current @ 50 bar 210 bar (3000 psi) 20 L/min...

EPV16 - Proportional valve Proportional flow control, normally closed, poppet 160L/min (42 USgpm) • 280 bar (4000 psi) EPV16A “A” style (nose in, side out) - In the de-energized position this valve remains closed from port 1 to port 2. When current is applied to the coil, a ontrolled increasing flow will be allowed from port 1 to port 2, in proportion to the current applied. “B” style (side in, nose out) - in the de-energized position the valve remains closed from port 2 to port 1. When current is applied to the coil, a controlled increasing flow will be allowed from port 2 to port 1. In...
