Designed for use with air or inert gas, SMC's VCHR can operate up to a maximum pressure of 6.0 MPa with a set range of 0.5 to 5.0 MPa. With large flow passages, and IS01179-1 conforming port thread sizes, high flow rates are ensured. A metal-sealed relief valve, and a polyurethane elastomer poppet improve durability. Expected service life is approximately 10 million cycles.
