CLA-VAL CRL-34 : Remote Set-point Pressure Sustaining Pilot
The Cla-Val Model CRL-34 electronic actuated pressure sustaining pilot control provides remote set-point adjustment and accurate pressure sustaining control on Cla-Val PCM50-01 series pressure sustaining valves. Remote set-point command signals can be from any SCADA-type control system using an analog 4-20 mA signal or by contact closure for cc/ccw rotation. The CRL-34 senses upstream pressure with a remote hydraulic connection. Operating on 12 to 24 VDC and consuming very little power, they are an ideal control system for remote valve sites and can be powered by a compatible Cla-Val turbine.
