Check Valve - Ball type (nonreturn valve) was the first valves at with a unique design. A very simple
but robust design with no critical mechanism involved.
All parts like hinge pin disc mechanism used in conventional valve are eliminated, and has put in a
reinforced rubber coated ball to arrest flow media in return condition.
This ball, moves totally out of the flow path when the pumping is on to give minimum head losses.
The spherical rubber coated ball seals perfectly on the rounded valve seat ensuring a totally leak proof
sealing.
This design offers other advantages like non clogging & self cleaning. In this virtually maintenance free
valves, if required, after prolonged usage, the on-line replacement of the ball is just a minute job.
* Lower power consumption
* Larger solid handling capacity
* Self cleaning, Non-Clogging
* Perfect Sealing
* Low pressure drop
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.
