CI038 Cast Iron Wafer Type Check Valve PN-16 (Wafer Type)

INTRODUCTION
Leader Wafer Check Valves are designed to prevent the reversal of flow in a piping system. Valve is activated by the flowing material in the pipeline. The pressure of the fluid passing through the system opens the valve, while any reversal of flow will close the valve. Closure is accomplished by the weight of the check mechanism, by back pressure. The eccentrically mounted hinge pin in combination with the disc seat guarantees a positive shut-off of the returning media.

• Wafer Type Single Disc design.
• Renewable resilient (EPDM / Nitrile) seats ensure Leakage Class IV (Zero Leakage).
• Very low face-to-face dimensions hence space required for mounting is less than 10% of that conventional Swing Check valves.
• Short wafer body enables mounting the valve with shorter length fasteners of lesser number compared to flanged swing check valve. Approximately 50% saving in cost of fasteners.
• Tightening torque to be applied on the companion flange bolting is lower due to face sealing O-ring.
• Practically maintenance-free due to fewer number of parts and simple construction
• Renewable resilient seat ensure Zero leakage.
• Suitable for insertion between flanges as per BS-10 table
• Less wear and tear of seat surface due to O-Ring type body seat facing.
• The need for flange gaskets during installation is totally eliminated due to the in-built face sealing ‘0’ rings provided on the sealing face.
• Either vertically (only upwards) or horizontally installed.
