BelGAS 300 Series - P302 Relieving Gas Pressure Regulator
The P302 Relieving Gas Pressure Regulator from BelGAS is a manual, direct-operated, spring-loaded adjustable pressure regulator. The P300 series is used in applications where pressure reduction is required. The regulator will reduce the risk of “shock” from abrupt changes of downstream conditions. This can help prevent safety equipment from shutting an operation down.
Features:- Minimize sudden downstream load change
- Wide pressure range
- P302 has internal relief valve for overpressure protection
- Compressors
- Gas Engines
- Service Regulators
- Boilers
