PRODUCT INFORMATION
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
TECHINCAL DATA
OPERATION
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 [1] to develop maximum hydraulic power. Dry pilot line pneumatic pressure [2] is applied, to a 3-Way Relay Valve (HRV-3) [3] , opening it. Through the override cock valve [4], the HRV-3 applies upstream pressure to the valve’s control chamber [5] 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 [6] traps high pressure peaks, ensuring that the valve remains locked in the closed position to maintain drip-tight sealing.
