C.r.i.air valve is connected with delivery pipeline to eliminate the trapped air in the system. Normally in horizontal pipeline, due to un-evenness in ground level, there will be an entry of air into the pipeline it results in pipe damages.
C.r.i. Energy efficient frictionless foot valves and reflux valves are basically swing type non return valves. Foot valves are available in screwed type construction and reflux valves have threaded portions at both the ends.
We are offering non return valves, reflux and non return valves are fitted generally in the delivery pipeline to avoid water hammer, up thrust and backspin effects in the pumping system.
We are offering check valves.Foot valve is placed at the lower end of the suction pipe of a centrifugal end suction pumpset to retain water in the pumpset casing and suction pipe to keep the pumpsets always in priming condition.
