The Model CRL-34 Electronic Actuated Pressure Sustaining Pilot Control provides remote set-point adjustment and accurate upstream pressure control on 350 Series Electronic Control Valves. Remote set-point command signals can be from Cla-Val Pacific’s VC-22D e-Controller or any SCADA-type control system using an analog 4-20 mA signal, by contact closure for counter-clockwise / clockwise rotation or through Modbus RTU.
The CRL-34 is an ideal companions to the products listed below, combining to create a highly effective control option for pressure reducing applications, including pressure optimization and water savings.

The CRL-34 is installed on Cla-Val 350 Series valves to maintain constant upstream pressure within close limits and require this pressure to be changed from a remote location. This pilot can be an effective solution for lowering costs associated with "confined space" requirements by eliminating the need for entry in valve structure for set-point adjustment. The 350 Series Valve can also be used for pressure relief, back pressure or unloading functions in a bypass system.
