Type 600康气通流量放大器 Ratio Relay Volume Booster Meet high flow requirements with a low flow pneumatic signal. 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. FEATURES •High Flow Capacity Allows flows up to 50 SCFM •Amplified Output Available in a signal to output pressure ratio of 1:1, 1:2, 1:3 and 1:6 • Stable Output Venturi aspirator maintains output pressure under varying flow conditions • Balanced Supply Valve Rolling diaphragm design makes unit insensitive to supply pressure variation •Optional Negative Bias 4 psi negative bias option allows "zero" of I/P's Flow Characteristics Regulated Pressure psig 1:3 1:6 1:1 1:2 Flow scfm Supply = 100 psig 0 5 10 15 20 25 30 35 40 45 50 25 20 15 10 5 0 20 15 10 5 Applications The Type-600 is used extensively for increased flow capacity, pressure amplication, or remote pressure control applications. This includes web tensioning, roll loading, control valve acuators, I/P volume boosting, cylinder actuation, clutch and brake control, and gas flow control
