Volume booster
Volume booster relay is used in pneumatic control valve which receives positioner’s output signal and supply air pressure actuator to reduce response and adjusting time. The Type 75 relay uses signal pressure to accurately control output pressure over a wide range of flow and supply pressure variation.
Features:
- Balanced valve design
- High flow capacity
- Field serviceable
- Multiple output ratios
- Negative biasing option
Air relay
The Type 79 relay is designed for applications where a precise control of flow is needed. This regulator offers low droop, high accuracy and fine adjustment sensitivity. The use of a Bellofram rolling diaphragm provides greater sensitivity and improved accuracy. The balanced pintle minimizes output pressure changes caused by fluctuations in supply pressure. Careful design and quality materials throughout assure long, trouble-free operation.
Features:
- Balanced Pintle
- High Flow Capacity
- Field Serviceable
- Large Port Sizes Available
- Air Piloted or Dome Loaded
- 200 PSIG Output
- Optional High Relieving (Type 79HR) and Valve Control (Type 79V)
