BelGAS Gas Pressure Reducing Regulator
The P133 has a wide range of pressure capabilities from 2" WC up to 10 psig. The compact BelGAS Type P133 reduces the effects of supply pressure changes on output pressure by way of a balanced diaphragm design for accurate control. With proper selection of options available, use the regulator in either low- or high-pressure applications. Units reliably operate over a temperature range of -20° to +150°F.
The bubble-tight shut-off feature makes the P133 ideal in residential and light industrial heaters and industrial burners, to reliably supply gas to furnaces, burners, light industrial heaters, and other appliances. No seat-to-seat adjustment is required.
