P119 CONTROL VALVE

Tight shut-off at maximum body working pressure
Easy installation
Leak detection and low seat leakage
Inline Maintenance
Steel body incorporates NACE #MR-01-75 compliant construction

Product Detail:

With available spring ranges from 3-15 to 30-60 psi, the compact Marsh Bellofram BelGAS P119 general purpose control valve may be used for on-off or throttling control functions, as well as heater fluid value control or gas distribution service. Pressure settings can be adjusted throughout each spring range via rotation of the adjusting screw. The unit’s easy installation and rugged construction allow it to be used with many mediums, including both corrosive and non-corrosive liquids and gases, with low seat leakage. For overall convenience and reduction of downtime, valve maintenance can be achieved inline and without actually removing the valve body from the line itself, provided pressure is removed and the valve isolated prior to attempting. Leak detection of actuator stem seals is achieved via a vent provided in the value actuator. The composition disc assembly and seat offer positive shutoff at maximum body working pressure.

Applications
• On-Off or Throttling Control
• Gas or Liquid Service
• Heater Fuel Valve Control
• Gas Distribution
