OCV | Digital Electronic Valve Series 22/88

MODEL 22 RATE OF FLOW CONTROL

Protects system from overpressure by exhausting excess pressure. The valve may only have to operate intermittently to prevent pressure surges that might occur

on pump start, pump stop,

or sudden downstream valve closure.

MODEL 22 PRESSURE REDUCING CONTROL

Valve keeps pumping system at a constant pressure by bypassing back to source. Provides accurate pressure control when system demand varies widely.

MODEL 88 LEVEL CONTROL

Valve allows flow when inlet pressure is above the set-point thus preventing inlet pressure from falling too low. Prevents demand from “robbing” the source, or keeps pump “on its curve.”

Operates automatically off line pressure.
Heavy-duty, nylon-reinforced diaphragm.
Rectangular-shaped, soft seat seal provides drip-tight Class VI closure.
Diaphragm assembly Guided top and bottom.
Throttling seat retainer for flow and pressure stability.
Easily maintained without removal from the line.
Replaceable seat ring.
Alignment pins assure proper reassembly after maintenance.
Valves are factory tested.
Valves are serial numbered and registered to facilitate replacement parts and factory support.
