Type P39 Configurable Gas Pressure Regulator

The BelGAS Type P39 configurable gas pressure regulator is the industry’s largest and most easily adjustable. Units are offered with a choice of three different seat materials, allowing the designer to custom fit for individual applications. In addition, our broad selection of six different outlet pressure spring ranges allows for more precise regulation of downstream pressure for better process control. Piping designs can be simplified by using any one (or all) of the regulator’s three standard outlet ports.
