PRODUCT INFORMATION
Bermad FC 700E-3X-BO Zero Pressure Solenoid Activated Foam-Concentrate Valve
The Bermad FC 700E-3X-N-BO is a Double Chambered hydraulically powered foam concentrate valve, which is electrically activated by a solenoid valve. The valve is actuated by fire water from the Main, which makes it independent from the foam concentrate line’s pressure. Hence it may operate when line pressure is low or even in nonpressurized systems. This makes it best suited for installation at the discharge of atmospheric tanks.
The valve is Fail-safe Close and designed with an “over the seat flow” opening to ensure drip-tight sealing and safe operation. The FC 700E-3X-N-BO replaces mechanical actuated valves or pilot-operated solenoid valves, providing safer operation of modern foam systems, thus assuring maximum reliability of the entire fire-fighting system.
FEATURES & BENEFITS
- Double chambered Actuation – Zero Line Pressure
- Obstacle free full bore – Uncompromising reliability
- In line serviceable – Minimum downtime and easy maintenance
- Electric Remote Opening – Automatically copntrolled
- 3-Way control system – avoids continuous releasing
TECHINCAL DATA
OPERATION
The BERMAD FC 700E-3X-N-BO is a Water Actuated Foam-concentrate valve, it is double chambered actuated valve, hydraulically powered opening and “over the seat flow” with Fail safe Close feature. The FC-700E-3X-BO is a “Y” pattern, diaphragm actuated, double chambered, water driven valve that required firewater external source, as a priming pressure to be able to activate. The water priming line pressure [1] is connected to both Lower [2] and Upper [3] control cambers. The pressure to the upper chamber is provided trough a manual override valve [4] and trough the 3-Way solenoid valve [5]. The check valve [6] traps high pressure peaks in the main line ensuring that the main valve remains locked in the closed position to maintain a drip tight sealing.
The 3-Way solenoid valve applies water pressure to the upper control chamber balancing the diaphragm and enable the spring to push the seal disc to the seat thus holding the main valve closed and sealed. When the solenoid is energized the valve upper chamber is vented while lower chamber is fully pressurized, the actuator is hydraulically powered, allowing the valve seal disc to open and fluid to flow through the valve discharge to the system.
