Brief Description

Rubber Flapper Swing Check Valve, Oil Control Bottom Buffer is a safety device mounted in the pipeline

or pump outlet to prevent the pump from inversed running due to the water hammer’s shock produced in

the sideflow of the medium when the pump stops.


And it features by the light flap, big opening, notable power saving, small fluid resistance, newstyle of

water hammer removal mechanism’s design, stable and reliable seal performance, wearable, long

duration, stable running, without vibration and noise etc.


Suitable for the pipeline related to the systems of water supply and drainage, firefighting, warming etc. or

the pump outlet to prevent both pump and pipeline from being damaged due to the water hammer

produced in medium’s back-flow.

Typical Installation

Wedge Ductile Iron Swing Check Valve DN15 ~ DN600 , Rubber Disc Check Valve


Brief introduction:

Rubber disc check valves consist of body, cover and rubber disc.


Inside of the rubber disc is steel plate, steel bar and reinforced nylon liner and the outside is rubber

and the disc life is more than one million openclose cycles.


The valves is designed with unimpeded bore, so the pressure loss is very little and no sundries pile

up in the body and it is easy to maintain this kind of valves.


The valves is used for feeding system and installed at the outlet of the pump to prevent the fluid

flowing backward and water hammering.


Also it can be installed at the inlet of inlet/outlet's bypass pipe to prevent the water in the cistern

flowing backward into the pipe.
