REGULATORS
Self-contained devices to monitor or control upstream or downstream gas pressure on vessels, sales lines, and supply lines.
Model P99
Gas Pressure Reducing Regulator
The BelGAS Type P99 gas pressure reducing regulator provides a broad range of controlled pressure ranges and capacities for use in a variety of distribution, industrial, and commercial applications.
The regulator’s high accuracy keeps constant inlet pressures to downstream equipment by accurately controlling distribution system pressures at widely varying flow rates and supply pressures. The device also eliminates the need for pressure-compensating meters by holding a steady pressure to the meter inlet.
Features:
- Minimizes sudden downstream load changes
- Wide pressure range
- No atmospheric bleed
- High accuracy
- Tight shutoff
- Easy to maintain
Applications:
- Natural gas distribution systems
- Gas supply to industrial boilers, furnaces, ovens and mixers
- Plant air service
- Oxygen and ammonia service
- Large commercial establishments such as shopping centers and schools
