CDHS-34 Electronic Actuated
Rate-of-Flow Pilot Control


The Cla-Val Pacific Model CDHS-34 Electronic Actuated Differential Pressure Pilot Control provides remote set-point adjustment and accurate differential pressure control for rate of flow control on Cla-Val Pacific 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 valve creates differential pressure used for 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. 

Product Advantages

Typical Application
The CDHS-34 Is installed on Cla-Val Pacific 340 Series valves to maintain flow rate and allow the flow rate to be changed from a remote location. It is also an effective solution for lowering costs associated with "confined space" requirements by eliminating the need for entry in valve structure for set-point adjustment. Additional pilot controls, hydraulic and/or electronic, are also available to perform multiple functions to fit exact system requirements.
