Type 6500/6600 Volume Booster

High Flow Capacity for Diaphragm or Piston Actuators

The Type-6500 aluminum and Type-6600 stainless steel volume boosters are 1:1 signal to output relays that are utilised in applications that require high flow capacity. They are available in 3/4" and 1" NPT with flow capacity of 350 and 400 scfm respectively, and an exhaust capacity of 100 scfm. Typically they are used to increase throttling speed of large volume valve actuators.  They are suitable for either diaphragm or piston actuators. A fixed deadband 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.

  • Flow Capacity: 400 scfm (11,320 Nl/min)
  • Temperature Limits: up to 93°C
