1. Introduction
The 34 Series electronic actuated pilots offer accurate and reliable control of the valve. 34 Series
pilots are a 4-20 mA standalone actuated controller calibrated via PC through a maintenance
port and able to remotely control any Cla-Val valve. The pilot setting can be adjusted with a
standard 4-20 mA signal, and 4-20 mA position feedback is available to cross check if requested
position is reached.
34 series pilots include:
•CRD-34 & CRA-34 “Electronic Actuated Pressure reducing pilot control”.
•CRL-34 “Electronic Actuated Pressure sustaining pilot control”.
•CDHS-34 “Electronic Actuated rate of flow pilot control”.
The 34 series includes the following features:
•Ideal for Pressure/Flow optimization
•Simplified Remote Valve Set-point Control
•Modbus RTU Communication
•Easy integration with VC-22D Electronic valve controller
•12 to 24 VDC Input Power
•Isolated input
•Reverse Polarity protection
•IP-68 Submersible
•Calibrated Via PC and VC-22D
