Type 600 Volume Booster

Meet high flow requirements with a low flow pneumatic signal

The Type 600 ratio relay volume booster is designed to use a pnuematic signal to produce an output pressure which has high flow capacity and can be amplified. 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. Using an independent supply pressure for greater volume, the Type 600 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 1:2, 1:3 and 1:6.
