Cast Iron Ball Check valve

Cast iron ball check valve is recommended for agriculture irrigation systems as a safety valve to prevent the water hammer and to maintain water column in delivery pipe. It is also used after pumps and boosters, lateral pivots and for long length irrigation distribution pipelines as it reduces pumping time resulting in energy saving.

Features

Simple and robust design by no mechanism involved

MS reinforced NBR coated ball for excellent and over years consistent performance

Minimum Head Loss: Clear passage equal to nominal valve dia gives non interuption to flow, resulting low energy consumption.

Delivers High Volume of water quickly with unrestricted full flow.

Self cleaning by rolling movement of ball avoid scaling inside or on ball.

Ball is the only moving part inside, avoid clogging and maintenance free performance

No drop leakage by installing valve in any direction due to its scaling free Leaded Tin Bronze ring.

Walls inside Check valves are expoxy coated gives free and frictionless movement to water and for longer life of ball.

Body and Cover Plate outside walls are enamel painted (RAL 5015).

½" Female threaded BSP/NPT port at Inlet of valve: Bypass/priming of pump if required.

Very less down time.

Arrow for correct installation of Check valve.
