Large Flow Capacity Volume Booster Rapid Stroke Capability in a Rugged Aluminum or Stainless Steel Casing The ControlAir Type-6500 aluminum and Type-6600 stainless steel volume boosters are 1:1 signal to output relays that are utilized in applications that require high flow capacity. 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 d ownstream 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. • Aluminum or 316 Stainless Steel Construction • ¾" or 1" NPT Porting • Integral Adjustable Bypass Valve Eliminates “hunting” by allowing the booster to directly respond to small incremental signal changes without opening the primary valve. • High Flow Capacity Large input signal changes open main valve to deliver up to 400 scfm (11,320 NL/min) for rapid actuator stroking • Soft Valve Seat Design Provides tight shutoff and eliminates leakage in steady state operation. • High Temperature Operation Up to 200°F (93°C) • Tapped High Output Exhaust Port 3/4" NPT exhaust port relieves 100 scfm (2,830 NL/min) at 5 psig above setpoint • 2 Gauge Ports - Optional Output Feedback Port Materials of Construction Materials Zinc Plated Steel Other trim Internal components Aluminum 316 Stainless Steel Stainless Steel
