P119 | Control Valve
BelGAS Regulators
The BelGAS P119 Control Valve is a versatile, diaphragm-operated valve designed for both on/off and throttling service in gas and liquid systems. Built for reliability and performance, it delivers tight shutoff and consistent control across a wide range of operating conditions.
Engineered for demanding environments, the P119 can be used in corrosive and non-corrosive applications, with NACE-compliant construction available for sour service. Its actuator design includes a vent to detect stem seal leakage, improving operational awareness and safety.
Designed with serviceability in mind, the valve allows maintenance and trim access without removing the body from the pipeline, reducing downtime and simplifying field repairs. With multiple spring ranges and material options, the P119 can be configured to meet a wide range of application requirements.
Typical Applications:
On/off or throttling control, heater fuel valve control, gas distribution systems
