QUALITROL 201/202/205 Small pressure relief devices
Rugged design provides trouble-free over pressure protection
Mechanical overpressure protection device provides pressure relief on transformers during overpressure conditions, automatically resealing once pressure has fallen. Available with a stainless steel pull ring attached to the to allow for manual operation. Optional port protection with cover for inhibiting matter from entering the valve body.
- Standard models have a one-piece brass housing with stainless steel spring, pull ring and viton o-ring seal
- Models have fixed or field adjustable pressure settings and are available with maximum flow rates from 35 SCFM to 200 SCFM
- Available dual sealing submersible design made entirely from stainless steel for special applications
Rugged design provides trouble-free over pressure protection
- All brass and stainless steel external construction
- Compact, low profile reduces damage risk
- Weather-resistant Viton O-rings withstand decades of service
- Stainless steel pull ring permits safe manual bleeding of pressure
