40-01/640-01 Rate of Flow Control Valve


Benefits & Features

The Cla-Val Model 40-01/640-01 Rate of Flow Control Valve prevents excessive flow by limiting flow to a preselected maximum rate, regardless of changing line pressure. It is a hydraulically operated, pilot controlled, diaphragm valve. The pilot control responds to the differential pressure produced across an orifice plate installed downstream of the valve.

40-25/640-25Combination Rate of Flow & Pressure Sustaining Valve


Benefits & Features

The Cla-Val Model 40-25/640-25 Rate of Flow and Pressure Sustaining Valve automatically limits the maximum flow rate, regardless of changing line pressure or demand. It also sustains the upstream pressure to a pre-determined minimum.

Install this valve where the water supply to a system must be limited to a preset flow to prevent lowering the supply pressure.

Benefits & Features

The Model 43-01/643-01 includes an orifice plate with a holder that should be installed one to five pipe diameters downstream of the main valve. If the check feature option is added and a pressure reversal occurs, the downstream pressure is admitted into the main valve cover chamber and the valve closes to prevent return flow.

49-01/649-01 Combination Rate of Flow and Pressure Reducing Valve


Benefits & Features

This valve is a hydraulically operated, pilot controlled diaphragm valve. The pilot system includes a direct acting pressure reducing pilot and a rate of flow differential control. The pressure reducing pilot is responsive to slight variations in downstream pressure and immediately controls the main valve to maintain the desired line pressure.

X52E Orifice Plate Assembly


Benefits & Features

The Cla-Val Model X52E Orifice Plate Assembly is typically used with Cla-Val flow control valves. The orifice plate is an essential component used to generate a specific, predictable pressure drop in the system. The X52E uses a wafer design holder which offers a compact lightweight assembly that is easy to install.
