Series PRH offers the highest available performance in a standard, spring-type regulator. Based on the same large area frictionless rolling diaphragm, poppet seat, isolated pressure sensing chamber and pressure balanced shaft of series PR, this valve uses higher capacity springs and an expanded base to accomodate the increased pressure settings. It is corrosion resistant, and also excellent for high purity and water applications. The standard connections are female NPT threaded ports. Socket, flanged and spigot connections are also available. Springs (non wetted) and external fasteners are stainless steel. Some Kynar PVDF components are used in the Natural Polypropylene and PTFE models for strength.
