Volume Booster

Volume booster utilises a signal pressure to produce an output pressure with high flow capacity, that can be amplified. Signal to output ratio available includes 1:1, 1:2, 1:3 and 1:6.

Categories: ,

The Type-600 ratio relay Volume Booster is designed to use a pneumatic signal to produce an output pressure which has high flow capacity and can be amplified. Using an independent supply pressure for greater volume, the booster relays up to 50 SCFM (1,400 Nl/min) flow capacity to a final control element such as a valve actuator. The standard signal to output ratio is 1:1, however, the Type-600 is also available with an amplified ratio of 1:1, 1:2, 1:3 and 1:6.

Applications

This unit is most useful for systems requiring the conversion of a low flow control signal to the higher flow requirements of an operating system.
