The Series 50-185 Gas Pressure Reducing Valve (GPRV) is a spring-loaded, diaphragm operated valve used in gas-handling systems which reduces varying gas pressure to a desired regulated pressure and maintains within close limits.
- Design simplicity and few operating parts mean a small, compact valve that is easy to install directly in a pipeline.
- Optional wall-mounting brackets are available for use with flexible connections.
When used in supply feed lines, the valve reduces the possibility of reliquefaction and improves gas regulation. For automatic operation, optional electric control components give reliable automatic shut-off.
- All valve arrangements can handle inlet pressures to 560 psi (38.5 bar) and temperatures to180°F (82°C).
- Kynar® (vinylidene fluoride resin) for chlorine or Sulphur dioxide or FEP (for ammonia) diaphragms and lead gaskets minimize the possibility of leaks. All electric operator arrangements shut off automatically if power supply fails.
- All valve body arrangements are weather-resistant for outdoor installation. The electric operator is a general purpose type and is UL listed.
- One valve body accommodates several seat-and- stem sizes for different capacities. The valve gives excellent regulation of discharge pressure over a flow range of 100 to 1 and a wide range of inlet pressures.
- Removable cartridges containing the seat-and-stem assemblies facilitate changing capacities and maintenance.
- Regulated gas pressure is easily set by adjusting spring load.
