OCV Control Valves has many valve designs to meet the variety of
requirements of water utility systems. By controlling pressure, rate
of flow, surge and pump control, OCV’s valves can help improve
the efficiency of both supply and distribution. OCV also has altitude
control valves to service elevated water tanks and a digital control
valves to interface with high level SCADA systems.
Series 94 Check Valve
The OCV Series 94 check valve is a simple on-off
valve that opens to allow forward flow when inlet
pressure exceeds outlet and closes tightly to prevent
backflow when outlet pressure exceeds inlet pressure.
    SERIES FEATURES

Non-surge opening and/or
closing when equipped with
adjustable opening and/or
closing speed controls

Equipped with valve position
indicator on all models.

Series 108 Pressure Relief Valve
In many liquid piping systems, it is vital that line pressure is
maintained within relatively narrow limits. This is the function of the
108 Pressure Relief / Back Pressure Series of the OCV control
valves. Installed in the main flow line, the standard Model 108-2
acts as a backpressure or pressure sustaining valve. In this
configuration, the valve maintains a constant upstream pressure
regardless of fluctuating downstream demand. When used in a
bypass line, the same model will function as a relief valve,
protecting the system against potentially damaging surges.
            SERIES FEATURES

Relief: Maintains a constant inlet
pressure by relieving excess high
pressure.

Sustaining: Prevents pressure from
dropping below a minimum.

Inlet pressure is accurate over a wide
range of flow.

Inlet pressure is adjustable with a
complete range of control springs.

Quick opening with controlled
closing.

Series 120 Flow Control Valve
The OCV Series 120 Rate of Flow control valve is designed
to control or limit flow to a predetermined rate, regardless of
fluctuations in downstream or upstream pressure.
    SERIES FEATURES

Self contained, including
the differential-sensing
orifice plate and pilot.

Flow rate is field adjustable
(within orifice bore range).

Extra-sensitive-differential
pilot specifically designed
for Rate-of-Flow application.

Works equally well on all
types of clean, non-abrasive
liquids.
