CRI Foot Valves, Color : Black

CRI Foot Valves that we bring forth are engineered to provide a trouble-free performance in the pump industry. These CRI Foot Valves are efficient frictionless foot valves. The reflux valves are basically swing type Non Return valves. CRI Foot Valves are available in screwed type construction and reflux valves have threaded portions at both the ends. They are specially designed to give an unrestricted smooth flow of water and thus reduce the frictional losses to minimum. Our CRI Foot Valves has 'K' value less than 0.8 and 'K' value for reflux valves are less than 0.5. Thereby, they reduce additional load on prime mover and also gives more discharge.
CRI Foot Valves are placed at the lower end of the suction pipe of a centrifugal end suction pump set to retain water in the pump set casing and suction pipe to keep the pump sets always in priming condition. 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. These CRI Foot Valves can also be used anywhere in the suction line of which the bottom end is entered into a bore pipe or tube well. The pressure withstanding capacity of Reflux valve and non-return valve are 1 bar and 15 bar respectively.

Salient Features :

• Sunction patin is almost straight to the pipe and hence frictional loss is very less
• Natural rubber flap totally prevents water leakage
• Ruggedly built with graded cast iron
• Compact design and easy to install
• Metal parts of foot valves are coated with bituminous paint to avoid rust formation
• It increases water discharge up to 20% and reduces energy consumption up to 10%
