The body is full waterflow path design, big flow, small resistance and the water head loss is smaller that of the swing type by 50. It is mountable vertically or horizontally and can be used for cold water, hot water, industrial and living sludge pipe networks, especially suitable for the submersible sludge pump.

Principle:

The heart of this valve is a reinforced rubber ball. The unique design of the valve allows free movement of the ball.

The ball moves to open position when the pump starts & allows free flow of liquid without any interference (See Fig.).

As the pump stops, the ball seats firmly against the metal seat due to its own weight & back pressure of the liquid (Mouse over fig.). This results in DROPLESS sealing.
