Festo’s DRVS is a compact, double-acting, semi-rotary vane drive for performing simple rotational or switching functions. The pneumatically activated DRVS comes in several standard sizes and can be supplied with 90, 180 and 270 degree swivel angles. Its extremely rugged design assures a long service life, even in harsh environments. The sealed housing protects against splash water and dust. Cushioning is provided by elastic PU material on the rotary vane in both end positions, while the bearings are protected with a shaft seal. Several accessories help users optimize the DRVS for a wide range of applications. The optional, matching position transmitter SRBS is used for sensing the end positions of the rotary vanes.
