Pressure Restricting Valves

Elkhart’s pressure restricting valves all feature rugged cast brass construction in your choice of finishes. The pressure restricting valves feature rubber seats and are rated for use at 175 psi. Although factory setting is recommended, all the pressure restricting valves are field-settable. Pressure restricting valves reduce pressure under flowing conditions and allow fire departments to override settings in emergency conditions.
UP Series valves not intended for use in salt water applications.
