A failsafe mechanism designed for critical or sensitive water systems where continuous operation of control valves is crucial. This double safety feature is based on a third control chamber that is integrated into the valve’s regular actuator. The third Control Chamber acts as a hot-backup mechanism for ensuring continuous operation of the control system in the event of malfunction in the valve’s main control loop or diaphragm.
During regular operation the failsafe mechanism is on standby, monitoring the main control loop. Once the operation of the valve deviates from its designated control parameters, the third chamber control loop immediately kicks-in replacing the operation of the faulty one. An optional dry contact switch can be added for triggering an alarm circuit whenever the failsafe mechanism is activated.

BERMAD 700-M5, 24″;DN600 Control Valve is a hydraulically operated, diaphragm actuated globe pattern valve. A unique hydro-dynamic globe valve design with a special Open Plug provide high flow capabilities. The basic valve is available in the standard configuration or with an Independent Flow Check model 700-M5-2S.

BERMAD 24″, 28″, 30″, 32″, 36″, 40″, 42″, 48″ 700  Series large size control valves are hydraulically operated, diaphragm actuated type.

The valve is comprised of two major components: the body assembly and the actuator assembly.
The actuator assembly is removable from the body as an integral unit. It consists of a lower & upper control chamber. It can be converted on-site from single to double chambered actuator and vice-versa according to the required control function.

These valves are designed for large flow applications (On-off valve, pressure reducing, pressure sustaining, pump control, level control, check valve, flow control, burst control, emergency shut-off valve etc.), where precise control is needed.

• Large scale pumping systems
• National and municipal water networks
• Reservoir and dam water level control
• Industrial water systems

The Bermad Model 700-2S Hydraulic Control Valve with independent Life Check is a hydraulically operated, diaphragm actuated control valve with an integra, life type, spring loaded non return valve that opens to allow flow in the required direction and smoothly closes drip tight to prevent back flow.

The Bermad Model 700-C2 Anti-Cavitation Control Valve is designed to operate under high differential pressure conditions without suffering cavitation damage
