Bermad FP 400E-4X Pneumatically 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 Pneumatic actuation also provides maximum safety in seawater and foam concentrate applications.
FEATURES & BENEFITS
- 3-Way control system – Avoids continuous releasing
- Smooth opening and closing characteristics – Prevents water surge
- One-piece molded elastomeric moving part – No maintenance required
- Quick cover removal – Minimal downtime
The Model FP 400E-4X is an on/off pneumaticlly remote controlled valve designed to open and close drip-tight in response to an external pneumatic pressure command. 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, 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 drip tight. Under FIRE condition, a dry pilot line pneumatic pressure drop, closes the HRV-3, which then vents the valve’s control chamber allowing the main valve to open. The Check Valve  traps high pressure peaks, ensuring that the valve remains locked in the closed position to maintain drip-tight sealing.
