500X Stainless Steel Pressure Sustaining and Relief Valve — PVPeW 2026

Description

A pilot-operated valve used either as a pressure relief valve on a bypass branch or as a pressure sustaining valve in the main line. In relief service it opens gradually when upstream pressure exceeds the pilot setting, avoiding water hammer. In sustaining service it stays closed until upstream pressure reaches the setting, protecting the minimum supply pressure of the main, especially during fire demand.
