CI086A Cast Iron Wafer Type Check Valve PN-16 (Flanged)

INTRODUCTION
Leader Dual Plate Check Valves are automatic, quick-acting valve designed to prevent the reversal of flow in piping system. The two valve discs, eccentrically embedded, have springs which force the valve to close in case no pressure is available. The pressure ofthe fluid passing through the system opens the valve diss, while any reversal of flow we close the valve discs. Closure is accomplished by the spring action and by back pressure

• Design Standard: API 594.
• Retainer-less Construction ensures that they do not drill entirely into the valve body to allow the hinge-pin and the stop-pin to be fitted with a dual-plate check valve, The feature ensures high integrity & tamper-proof design, ensures no leakage from the body.
• Flanged type compact design to take lesser space than the Reflux 41 Swing Check Valve.
• Being light in weight has more rugged construction than the standard Swing Type Check Valve, which needs expensive foundation and special supports.
• Less wear and tear of seat surface due to resilient integrally moulded body seating face.
• Stopper pin prevents the discs from coming into contact with each other and thus prevents disc damage. The stopper pin also prevents spring failure by ensuring that the discs don't travel beyond the full-open position.
• Low cracking pressure design (operable at low pressures).
• Independent spring design features also available which gives less scrubbing of disc & independent movement of discs.
• Inherently non-slamming, no external devices/attachment required.
• Water hammering effect is minimized in this design, since the closing of valve does not depend upon any back pressure or flow.
• Either vertically (only upwards) or horizontally installed.
• Flanged ends as per ASME B16.1 CL-125 (FF).
