The SMC VCA31-5DO-CEM00256 is a high-performance, poppet-type 3-port air operated valve from the VCA series. Engineered for reliability and a high flow rate, this compact valve is suitable for a wide range of pneumatic applications, including cylinder actuation and air blow systems. Its robust construction ensures a long service life and consistent performance even in demanding industrial environments. This model operates as a Normally Closed (N.C.) valve, meaning it remains closed until an external air pilot signal is applied to actuate it.
