Description
Bermad FP 400E-5X Hydraulically Operated Remote Controlled Monitor Valve
Bermad Remote Controlled On-Off valves replace motor driven valves or actuated quarter turn valves. They are especially suitable for oscillating or remote controlled monitors, and for installation in modern foam systems where a shut-off function is required.
The Hydraulic actuation features boosted local pressure release from the valve’s control chamber, providing maximum safety in systems with long hydraulic remote control piping lines.
Operations
The Model FP 400E-5X is an on/off solenoid controlled valve designed to open and close drip-tight in response to an electric signal, using external pneumatic pressure (see data for minimum air pressure supply). It is a line pressure driven, diaphragm actuated globe valve, which harnesses line pressure to develop maximum hydraulic power. Dry pilot line pneumatic pressure is applied, through a 3-Way Solenoid, to a 3-way Relay Valve (HRV-3), opening it. Through the override cock valve, the HRV-3 applies upstream pressure to the valve’s control chamber closing the main valve.
The Model FP 400E-5X can be supplied in either the standard normally closed (energize to open) or the optional fail safe open (energize to close) configuration. The solenoid can be supplied in various voltages and specifications. The Check Valve [7] traps high pressure peaks, ensuring that the valve remains locked in the closed position to maintain drip-tight sealing
