Overview

The Metrex Model EAMDF-800MF-3W valve is an 8″ 3-way, electric actuated seawater regulating valve typically used to modulate the cooling water through a condenser in response to a control signal from the condenser. Refrigerant head pressure is maintained over a wide range of operating conditions for a maximum system operating efficiency.

Features

Valves can be mounted in any position without affecting performance. However, consider the accessibility of the electrical connections and the manual hand crank.
The valve features a Rotork MV-1500 Series linear actuator. The MV-1500 Series is a full featured unit with the ability to accept various analog control signals.
The built-in servo drive amplifier controls the stepper motor’s speed and direction. It also controls the actuator end limits, motor torque, deadband and 4-20mA transmitter.
The design offers smooth, highly accurate positioning, with positive position locks when not in motion.
