P133 Gas Pressure Reducing Regulator

The BelGAS P133 gas pressure reducing regulator is used in commercial and industrial applications such as furnace and burners, where accuracy and sensitivity are critical. Offered with a wide range of pressure capabilities within a single regulator, from 2" of water column up to 60 psig, the BelGAS P133 reduces the effects of supply pressure changes on output pressure via a balanced diaphragm design for accurate control. With user selection of appropriate options, the regulator can be further utilized in either low- or high-pressure applications. Units are designed to reliably operate over a temperature range of -20° to +150°F (-29° to +66°C). In addition, the bubble-tight shut-off feature makes the P133 a reliable means of supplying gas to furnaces, burners, light industrial heaters and other appliances. No seat-to-seat adjustment is required.
