Flow Control

Cla-Val flow control valves prevent excessive flow by limiting to a preselected maximum rate, regardless of changing line pressure. They are hydraulically operated, pilot controlled, diaphragm valve. Other combinations are list below.

Flow Limiting

Flow Limiting

Cla-Val Models 40GE-01/NGE40-01 Flow limiting valves regulate flow to a pre-
selected maximum rate, regardless of changing line pressure.  Find out more

Flow Limiting + Non Return

Flow Limiting + Non Return

Cla-Val Models 41GE-01/NGE41-01 Flow limiting valves regulate flow to a preselected
maximum rate. If a pressure reversal occurs, the downstream pressure is admitted in
the main valve cover chamber closing the valve to prevent return flow.

Flow Limiting + 4-20mA Remote Set-Point

Flow Limiting + 4-20mA Remote Set-Point

CLA-VAL models PCM-40GE-01/PCM-NGE40-01 valves regulate flow to a preselected
maximum rate. The valve uses a CDHS-33 actuated pilot control accepts a remote set-
point command input and makes set-point adjustments to the pilot.

Flow Limiting + Pressure Reducing

Flow Limiting + Pressure Reducing

Cla-Val Models 49GE-01/NGE49-01 combination rate of flow & pressure reducing
valves reduce a higher inlet pressure to a lower downstream pressure when the flow
rate is below a preset maximum.

45-01 Flow Limiting + Pressure Sustaining

45-01 Flow Limiting + Pressure Sustaining

Cla-Val Models 45GE-01/NGE45-01 are designed to limit flow rate to a pre-selected
maximum value to a preselected maximum rate, regardless of changing line pressure
and sustain a minimum upstream pressure.

Flow Limiting + Solenoid Shut-Off

Flow Limiting + Solenoid Shut-Off

Cla-Val Models 43GE-01/NGE43-01 Flow limiting valves regulate flow to a preselected
maximum rate, regardless of changing line pressure. The solenoid is energised or
de-energised (as specified) to close the valve drip tight.

Flow Limiting + Float Over-Ride

Flow Limiting + Float Over-Ride

Cla-Val Models 40GE/CF9/NGE40/CF9 Flow limiting valves, regulates flow to a
preselected maximum rate, regardless of changing line pressure. The valve opens
when the water level reaches a preset low level and closes drip tight when the level
reaches a preset high level.
