Watts Stainless Steel Electronic Control Valve (for Electric Valve Positioning) 933GS

Designed to be electrically positioned to control flow, pressure, level or temperature for water applications. By alternately energizing the (2) solenoids, the valve can be positioned to maintain a desired value. The valve is normally interfaced with SCADA systems or Programmable Logic Controllers that compare a Process Variable (PV) to a desired setpoint, and alternately energize the solenoid pilots to throttle the valve open or closed until the PV reaches the desired setpoint. The valve also has provisions for manual operation in the event of power outage.
