The Cla-val Model VC-22D is a single valve controller designed to enable remote control of electronic valves in water treatment plants or distributed systems.
It also serves as an interface between a SCADA system and other devices installed on or around the valve, such as flow meters, pressure transmitters, and position indicators. For ease of use, the controller is pre-loaded with a wide variety of typical valve applications (ValvApps™); these include flow control with a flowmeter, pressure control with upstream or downstream feedback, ratio control with two flowmeters, and modulating level control with level and flow feedback.
Additional features of this industry leading packaged solution include standard alarm outputs, logging and totalizer capabilities, local operator interface and graphical display, the ability to handle multiple analog and digital inputs/outputs, and extremely low power consumption. The VC-22D is the culmination of 25+ years of experience in the electronic valve control arena and nearly 80 years of designing and manufacturing automatic control valves.
This controller was developed by controls experts in collaboration with industry experts and municipal operators to provide capabilities well beyond those of traditional water system control valves – highly customized valve applications with local control are now possible.
