| Body : Cast iron, ductile cast iron ,WCB | ||||
| Bonnet : Cast iron, ductile cast iron, WCB | ||||
| Ball : cast steel coated with neoprene | ||||
| 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.
* 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.

CF8 PN40 Wafer Disco Check Valve For Petroleum Or Vapour , SUS304 Single Disc
Application:
Valve is used for preventing the back-going of medium in pipelines and equipments, and the pressure
of medium will bring the result of opening and closing automatically.
When the medium is back-going, valve disc will automaticaly closed to avoid accidents.
