Large Flow Capacity Volume Boosters

Large flow capacity volume boosters have rapid stroke capability in a rugged aluminum or stainless steel casing.

Categories: ,

The Type-6500 aluminium and Type-6600 stainless steel large flow capacity volume boosters are 1:1 signal to output relays that are utilised in applications that require high flow capacity. Typically they are used to increase throttling speed of large volume valve actuators. They are suitable for either diaphragm or piston actuators. A fixed dead-band and adjustable bypass valve combine to allow small incremental downstream adjustment without opening the main booster valve. The bypass valve is used to adjust dynamic response to provide stable operation over a wide range of actuator sizes. Rapid stroke capability in a rugged aluminium or stainless steel casing.
