EACD-250-3W Valve

Overview

The Metrex Model EACD-250-3W is a 2-1/2″ 3-way, electric actuated seawater regulating valve typically used 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 maximum system operating efficiency.

Features

Valves can be mounted in any position without affecting performance.
An orifice cylinder positions proportionally in response to a 4-20mA control signal to the actuator. An opening in the orifice cylinder allows one port to open as it covers the other. Adjustable limit switches in the actuator determine the two extreme positions of the orifice cylinder.
All electrical connections are provided on two MIL-DTL-5015 connectors.
Mechanical stops are provided on the valve actuator as a safety feature to protect the valve from damage due to manual or automatic operation past the limits of the valve.
Electrical limit switches OLS1 and CLS1 provide the means for stopping valve rotation at its endpoints of travel. A visual position indicator on top of the actuator shows an open, closed or interim valve position.
Torque limitation is provided to protect both the motor and the valve (OTS1 and CTS1). The actuator motor contains built-in thermal protection.
The actuator provides remote position indication/feedback via a 4-20mA position output module (loop powered). A visual position indicator on top of the actuator shows an open, closed or interim valve position.
