Product DescriptionThe Cla-Val Model VC-22D is a controller designed toenable remote control of electronic valves in waterplant or distribution systems. It also serves as aninterface between a SCADA system and other devicesinstalled on or around the valve (such as a meter).
For ease of use, the controller is pre-loaded with awide variety of typical valve applications(ValvApps™). Additional custom ValvApps™ can becreated by Cla-Val to meet any operationalrequirement.
Pre-Loaded Typical ValvApps™ include:• Flow Control with Mag Meter or e-Flowmeter
Feedback• Pressure Control with Upstream or Downstream
Feedback• Position Control with Position Feedback• Modulating Level Control with Level and Position
or Flow Feedback• Metering Valve with Position and DP or P1-P2
Feedback• Ratio Control with 2 Flowmeter feedbacks• Altitude On/Off Level Control with Delayed
Opening and Level Feedback• Pressure Management with CRD-33 and Flow

Controller Applications

VALVE FUNCTIONSPID
PID ControlUsed in maintaining a control valve at setpoint.
Uses a graphical function, allowing the userto make different signal types (for example: flow and pressure). The user also has the abilityto make relationships as a function of time. This is the primary function employed in pressuremanagement/water savings applications.
Control Curves
Retrans
Used to take “action” (or alarms) on an input,output, or variable when a programmablecondition is met.
Actions
Keeps track of total volume as a function of time.Customizable units & reset functionality allow forsimplified set-up and configuration.
Totalizer
Used to retransmit any input signal, variable,or calculation to a SCADA system. Retransmission outputs include analog 4-20mAor digital (contact closure).
Retransmission
Used to return an accurate flow rate without having a flow meter installed. Using a valveposition transmitter & DP transmitter, thisfunction will calculate flow.
