"Non-return valves with hydraulic damping system (NVTD)"
AB non-return valves with counter weight can be equipped with hydraulic damping system for adjusting the
closing time. With the damping system the opening and closing time can be reduced, and the water hammer
effect can be prevented by reducing the damping time.
Application: To provide non-slam performance in places where water return through the valve is permitted.
A flow control valve can adjust the opening and closing speed of non-return valve disc.
