Type 650

Type 650

Positive Bias Relay

Category: Volume regulator/booster

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. 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 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 signal to output ratio of 1:2, 1:3 and 1:6.
