Cla-Val Models 133-01 and 633-01 Metering and Flow Rate Control Valves are completely self-contained and utilize the VC-22D Electronic Valve Controller to accurately meter and/or control flow rate when used on valves with pressure differentials of less than 100 psid. 

Typical applications for 133-01 and 633-01 Metering and Flow Rate Control Valves are in fluid delivery systems where the flow rate is measured and changed from a remote location such as a SCADA system, using the VC-22D Electronic Valve Controller as the interface.
