Differential Pressure Reducing Regulator
Category: Differential Pressure Regulator, General Service
Models 1000HP-1+6 or 1000HP-1+8 are differential reducing regulators used to maintain a relatively constant pressure differential between the fluid loading pressure – P Load, and the valve’s outlet pressure – P2, with P2 pressure higher than P Load pressure. Model 1000HP-1+6 is a single-diaphragm differential construction.
Model 1000HP-1+8 is a double-diaphragm differential construction. A double-diaphragm design prevents the fluid passing through the body from mixing into the loading fluid pressurizing the spring chamber in the event of a diaphragm failure. The design takes advantage of all the features of the basic 1000HP reducing regulator; see Technical Bulletin 1000HP-BASIC-TB. The availability of optional construction and body and trim materials is limited to those indicated in this Technical Bulletin.
