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 moulded (bonded)
version and offers 100% bi-directional sealing against
vacuum
to rated pressures of PN10.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.
