Spirax-Sarco BRV2S-1/2-NPT Pressure Regulator

Spirax-Sarco BRV2S-1/2-NPT Pressure Regulator is a compact direct-acting valve designed for steam and compressed-air service, with a 1/2 in NPT end connection configured for point-of-use regulation. This variant provides a downstream set-pressure range of 0.14 to 1.7 barg (spring-selected), supported by a maximum differential pressure capability of 19 bar and a typical reduction ratio of 10:1; the BRV2S family notes a documented maximum downstream set pressure of 8.6 bar g. The valve features a ductile iron body with a stainless steel bellows and is offered in screwed BSP or NPT connections from 1/2 to 1 in, plus DN15 to DN25 flange options, making it suitable for integration into small steam or instrument-air circuits. The BRV2S assembly is rated for temperatures up to 410°F (210°C), with the model intended for direct regulation rather than pilot operation.
