Cla-Val Pacific Models 340-02 and 3640-02 Electronic Actuated Rate of Flow Control Valvea combine the precise control of our field proven hydraulic pilots and simple remote valve control. Models 340-02 and 3640-02 valve controls flow by limiting flow to a pre-selected maximum rate (within a four to one ratio), regardless of changing line pressure. using the Cla-Val Model CDHS-34 actuated pilot control.
The valves are designed to be used with supervisor control systems (SCADA), having an isolated remote analog set-point output and a process variable flow transmitter input using the VC-22D Electronic Valve Controller as the interface. It is also an effective solution for lowering costs associated with “confined space” requirements by eliminating the need for entry into valve structure for set-point adjustments and system information. Additional pilot controls, hydraulic and/or electronic, can be easily added to perform multiple control functions to fit exact system requirements.
