NON RETURN VALVES

Normex Valves manufactures Non Return Valves. It is used for backward flow of muddy, sandy and clear water, sewage, waste water, viscous liquid, paper stock, slurry. Principle of operation: 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 and allows free flow of liquid without any interference. As the pump stops the ball seats firmly against the metal seat due to its own weight and back pressure of the liquid.
