IVGKN Butterfly Valve

Intervalve’s GKL series valves are designed to meet the demanding requirements of the general utility valve market with the HVAC segment in particular. IVGKL is a truly fit & forget valve, which requires minimal maintenance. The body liner which also functions as the soft seat, comes in an integrally molded (bonded) version and offers 100% bi-directional sealing. The wafer style body has universal design to fit between pipe flanges of almost all popular flange standards.

Key Features:

• Integrally molded seat liner on the body, which ensures excellent dimensional stability & guaranteed seat tightness.
• Seat liner extending on to the contact faces ensures perfect sealing and eliminates the need for separate flange gaskets.
• Unique triple sealing system for shaft sealing ensures zero leakage of the media past the shaft seals.
• Narrow land disc ensures perfect sealing with least operating torque requirements.
• A fully universal body design ensures fitment of the valve between companion flanges of all popular standards (viz: ANSI, BS, DIN, JIS, IS etc. ).
• A ten position notch disc and handlever ensures locking of the valve in 8 intermediate position in addition to closed and open position. Handlever lockable through pad lock for tamper proof positioning.
• Body castings made of superior FG 260 grade cast iron to ensure additional strength.
• Valve disc made of ductile cast iron instead of cast iron to withstand against possible water hammer or pressure surges.
• A truly line size body bore to ensure maximum flow capacity with the lowest pressure drop.
• Shafts made of martensitic stainless steel to ensure maximum strength and torsional rigidity.
• Both top and bottom shaft swiveling are guided by self – lubricated PTFE bearings.
• Fool proof handlever designed to prevent accidental pinching of hand between the handle and locking lever.
