This unique valve provides both high performance and long life in the toughest of environments and features a truly variable orifice for throttling control of abrasive slurries.
Features & Benefits:
Designed to provide a safe, efficient method of switching from an active pressure relief device to a standby, maintaining system overpressure protection regardless of Safety Selector Valve position.
Provides high Cv values, resulting in less than 3% pressure drop to the active PRV inlet, when used with the largest API orifice available in a given valve size, in accordance with the recommendations of API RP520 Part II and ASME Section VIII, Division 1, Appendix M, helping reduce the possibility of destructive chatter of the PRV.
Requires only one minimally sized penetration into the vessel or pipe, reducing costs.
Reduces field installation costs and space requirements through preassembled and compact design.
Provides process isolation of standby pressure relief device.
