Model VC-22D Valve Controller

Product Description

The Cla-Val Model VC-22D is a controller designed to
enable remote control of electronic valves in water
plant or distribution systems. It also serves as an
interface between a SCADA system and other devices
installed on or around the valve (such as a meter).

For ease of use, the controller is pre-loaded with a
wide variety of typical valve applications
(ValvApps™). Additional custom ValvApps™ can be
created by Cla-Val to meet any operational
requirement.

MODEL

VC-22D

• Provides remote or local set-point control for valves in a

variety of fluid applications

• Highly accurate and stable valve control

• IP-68 Submersible

• Controller is supplied with pre-loaded ValvApps™ for

most common valve functions

• Custom ValvApps™ can be created using Valve Functions

to meet unique application requirements

• Custom ValveApps can be pre-loaded prior to shipping

• Monitors and displays multiple processes with accurate

retransmission of parameters to SCADA systems

• Supplied with Standard Alarm Outputs

• Logging capabilities

• Low power consumption: less than 3 watts

Controller Applications

Pre-Loaded Typical ValvApps™ include:

• Flow Control with Mag Meter or e-Flowmeter

• Pressure Control with Upstream or Downstream

• Position Control with Position Feedback

• Modulating Level Control with Level and Position

• Metering Valve with Position and DP or P1-P2

• Ratio Control with 2 Flowmeter feedbacks

• Altitude On/Off Level Control with Delayed

• Pressure Management with CRD-33 and Flow

VALVE FUNCTIONS

PID Control

Used in maintaining a control valve at setpoint.

Uses a graphical function, allowing the user
to make different signal types (for example:
flow and pressure). The user also has the ability
to make relationships as a function of time.
This is the primary function employed in pressure
management/water savings applications.

Control Curves

Used to take “action” (or alarms) on an input,
output, or variable when a programmable
condition is met.

Actions

Keeps track of total volume as a function of time.
Customizable units & reset functionality allow for
simplified set-up and configuration.

Totalizer

Used to retransmit any input signal, variable,
or calculation to a SCADA system.
Retransmission outputs include analog 4-20mA
or digital (contact closure).

Retransmission

Used to return an accurate flow rate without
having a flow meter installed. Using a valve
position transmitter & DP transmitter, this
function will calculate flow.
