BV: Big Volume Booster

Actuation accessories

The Big Volume Booster (model BV) is designed to meet high speed control applications. It produces a high volume boosting action and contains an integral stabilizing by-pass valve, adjusted by a screwdriver turning the adjustment screw in the body. By opening this valve it is possible to improve the stability of the positioner – volume booster – actuator circuit. BV was specifically designed to be piloted by a high CV positioner (such as our FT Positioner).

Exclusive manifold mounting system. It is a special STI application to connect our accessories. Fittings or nipples are not necessary as the connection is achieved using machined connection faces with sealing o’ring. This system saves time for assembly, reduces cost on items such as fittings, reducing inventory and the shortened dimensions save space.
