SMC VEF3141-1-03 Electro-Pneumatic Proportional Valve

SMC VEF3141-1-03 Electro-Pneumatic Proportional Valve is a flow-type electro-pneumatic control valve that modulates compressed-air flow to a pneumatic actuator in proportion to input current, enabling precise speed and force control in automation systems. The unit consists of three ports (P, A, R) with Rc 1/2 port threads and is driven by a 24 VDC coil. The model designation VEF3141-1-03 specifies a flow-type (VEF) valve in SMC's electro-pneumatic proportional valve family, designed for direct proportional control of flow with a P (pressure supply) port, an A (actuator) port, and an R (exhaust) port. It is rated for up to 1.0 MPa and is commonly used to control the actuation of pneumatic cylinders, clamps, and grippers in automated machinery.
