CI029 Cast Iron Butterfly Valve PN-16 (Wafer Type)

INTRODUCTION
Leader Butterfly Valves are designed to meet the flow control requirement of plumbing, fire-fighting and HVAC application. The body seat is vulcanised in-situ onto the body and offers 100% bi-directional sealing. The lugged wafer-style body has universal design to fit between flanges of all almost all standards.

• Design Standard: BS 5155, EN 593, API 609 CAT. A.
• Lugged Wafer type design makes it compact and takes lesser space.
• Dynamic sealing of concentric disc is obtained with vulcanised rubber seat at very low torque.
• High-precision disc external profile for smooth operation & tight shut-off sealing with low operating torque.
• Moulded rubber body seat extending on to the contact faces ensures perfect sealing and eliminates the need for separate flange gaskets.
• Notch plate ensures the locking of the hand lever at different positions in addition to open and closed positions.
• Shaft sealing is ensured by double sealing of Bush and ’0’ ring combination.
• Body castings made of superior FG 260 grade cast iron to ensure additional strength.
• Valve disc made of ductile iron with epoxy coating offers high strength against pressure.
• Shaft made of martensitic stainless steel to ensure maximum strength and torsional rigidity.
• Two-piece stem design which is precisely guided between the PTFE bush & Rubber ‘0’ Rings to prevent leakage, corrosion, and stem seizure.
• Taper disc holder pins to ensure shockproof shaft to disc connection & suitability of replacement at field.
• Easy visual control of open/closed position marked on the notch plate.
• Operation mode manual, gear, electric, pneumatic.
• Available with locking arrangement on request.
• Temper Switch / supervisory limit switches option available on request.
• Top flange as per ISO 5211 to suit F Series flanges of Gears and Actuators.
