SMC VEP Electro-Pneumatic Proportional Valve (Pressure Type)

SMC VEP pressure-type electro-pneumatic proportional valve, a 3-port valve that steplessly controls output pressure in proportion to the solenoid current (electric pressure-reducing valve).

Key features

3-port pressure control in body sizes 2 and 4
Set pressure ranges 0.05-0.65, 0.1-0.9 and 0.005-0.15 MPa
Exhaust side full-open area equal to supply side: large relief capacity
Proportional solenoid driven by VEA25 power amplifier, DIN terminal
Rc1/4 to Rc3/4 ports; G/NPT/NPTF on order
