EHOMDFX-400LNF-3W Valve

Overview

The Metrex Model EHOMDFX-400LNF-3W is a 4″ 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 must be mounted with the valve stem vertical in a horizontal flow line.
The hydraulic unit is bi-directional and incorporates load check valves that prevent drifting after actuation to maintain precise positioning.
A bi-directional differential pressure switch acts as a travel limit switch in both directions of stem travel. It cuts power on an increase in pressure differential between the cylinder high side and low side for each direction of travel when the limit of travel is reached.
The hydraulic unit operates at a nearly constant displacement rate in both directions independent of load and the hydraulic cylinder is sized for full-stroke times of approximately 20 seconds in either direction. A hand pump with handle is provided for manual operation.
