Electronic Control Valve for Electric Valve Positioning
Series LFM113-40, LFM1113-40 Electronic Control Valve is designed to be electrically positioned to control flow, pressure, level or temperature for water applications. It is a throttling valve controlled by two 2-way solenoids installed in the pilot control system. By alternately energizing the solenoids, the valve can be positioned to maintain a desired value. The valve also has provisions for manual operation in the event of power outage. The Electronic Control Valve is normally interfaced with SCADA systems or a Programmable Logic Controller that compares a Process Variable (PV) to a desired setpoint, and energizes the solenoid pilots to throttle the valve open or closed until the PV reaches the desired setpoint. The valve is constructed with two normally closed solenoids allowing the valve to hold last position upon power failure. The valve may also be configured to open fully or close drip tight upon power failure if desired.
