Spirax Sarco 0459381 BVR2 Valve and Seat Assembly

Spirax Sarco 0459381 Valve and Seat Assembly is a 1 in spare part for BRV2S direct-operated pressure regulator valves, designed to replace the worn valve seat and related components to restore accurate downstream pressure control in steam systems. This kit is specified for BRV2S 1 in direct-operated regulators and typically weighs about 2 lb, making it a compact rebuild component suitable for routine maintenance or field service. As a Spirax Sarco OEM part, the assembly ensures proper fitment within the BRV2S family and supports reliable regulation by restoring the seating surface and mating geometry critical to leak-tight operation. Applications include industrial steam distribution networks and process plants that rely on precise downstream pressure control to protect equipment and maintain product quality. The 0459381 valve and seat assembly is marketed as a dedicated replacement part for the BRV2 series, enabling technicians to perform valve rebuilds without sourcing non-spec parts, and it aligns with Spirax Sarco’s spare-parts strategy for BRV2S systems.
