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.

  • 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.
