Cla-Val products

The Model CRL-34 Electronic Actuated Pressure Sustaining Pilot Control provides remote set-point adjustment and accurate upstream pressure control on Cla-Val 350 Series Electronic Control Valves. Remote set-point command signals can be from Cla-Val’s VC-22D e-Controller or any SCADA-type control system using an analog 4-20 mA signal, by contact closure for counter-clockwise/clockwise rotation or through Modbus RTU.

The Cla-Val Model CDHS-34 Electronic Actuated Differential Pressure Pilot Control provides remote set-point adjustment and accurate differential pressure control for the rate of flow control on Cla-Val 340 Series Control Valves. Remote set-point command signals can be from any SCADA-type control system using analog 4-20 mA signal, by contact closure for cc/ccw rotation or through Modbus RTU. A precision orifice plate installed with a valve creates differential pressure used for the rate of flow control by the CDHS-34. Operating on 12 to 24 VDC and consuming very little power, it is an ideal control system for remote valve sites that may even be solar-powered.
