intervalve butterfly valve
Intervalve's GKL series valves are intended to meet the demanding requirements of the overall utility valve market with the HVAC fragment specifically. IVGKL is a genuinely fit and forget valve, which requires minimal maintenance.

The body liner which additionally works as the soft seat, arrives in an integrally molded (fortified) form and offers 100 percent bi-directional fixing. The wafer style body has widespread plans to fit between pipe flanges of practically all well known 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.
