Medium :  water and weak corrosive fluid 

 

Applications:

Flanged Ball Check Valve uses the rubber covered roller as the disc, when, under the action of the 

medium, can roll up and down along with the integral sliding path inside the valve so as to open or 

close it. 

 

And it features by good tightness, silent close and no production of water hammer. 

 

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. 

 

The medium temperature:0~80℃.

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.

*  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.
