Severn’s W-Series Pneumatically Operated Spring & Diaphragm Actuator is designed to satisfy the majority of general Control valve applications and is widely used in industrial flow control, oil & gas, power generation, and process automation systems.
With proven reliability, even in the most adverse climate conditions and temperatures, the range compromises three basic actuator sizes which, when combined with different spring ranges, provide a travel capability of up to 3 1/2 (89mm). The spring air fail action delivers crucial reliability for critical applications and a pre-compressed bench set is available across the range of fitted springs making it a highly dependable choice for severe‑service and high‑cycle valve automation requirements.
Severn W-Series Diaphragm Actuators Design Features:
- High power, fast response
- Operates from low-pressure air supply
- Low-stressed, positive spring fail action in either air fail open or close orientation
- Field reversible to change fail safe position
- Steel construction with minimal parts for low-cost, trouble-free operation and maintenance
- The assembly is bolted to a cast yoke combining lightness with mechanical strength
- Engineered for precision control valve performance
- Suitable for globe valves, choke valves, and general process control valves
- Optimised for pneumatic valve automation and reliable fail-safe operation
