K600HP E-SEAL KNIFE EDGE GATE VALVE
FEATURE:
K600 HP series Knife Gate Valve is a High Performance bi-directional valve designed for High
Pressure applications. This valve is a 300 class valve will withstand up to 40 bar working pressure.
Rigid body and Seal construction will ensures long life to the valve. UHMW material ring guides the
gate during opening and closing and protects the seal from damage. Free holes provided in the
flange bolting is help full during pipeline commissioning. Both Gland and Gland less packing will
be available on request. Rubber lined and in build ‘O’ Ring provided in the retainer ring will increase
the packing efficiency. The Sleeve are easily replaced without disassembling the valve. The flushing
plate option allows for periodic cleaning of the lower discharge vent and allows flushing as needed.
A cavity free flow path offers minimum pressure drop.

K1500 KONCH KNIFE EDGE GATE VALVE
FEATURE:
K1500 KONCH Knife Gate Valve is a High abrasive resistance bi-directional valve designed for Mining, Mineral
processing and Coal fired power palnt applications. This valve is a ANSI class 150 rated valve and shall withstand
up to 10 bar working pressure. Replaceable highly abrasive resistance premium urethane moulded primary seal
shall withstand up to 120°C and give high resistance to corrosion and erosion. Valves perform extremely well in
both large and fine coarse mineral processing , and are built to withstand the world’s most severe duty abrasive
slurry applications. Purgeless keros valve ensures zero leakage to the atmosphere and provides highest safety
to adjacent costly equipments. Self - flushing design avoids trapping of solid particles in the beveled inner
surface of seal.

Keros field replaceable urethane liner is
superior wear life compared to resilient seats
and sleeves. It is durable, abrasive resistant,
and economical to replace.
Keros extremely thick, robust gates are
guaranteed not to bend, which contributes
to maximum wear life between rebuilds.
System downtime due to premature knife
gate failure is reduced to the absolute
minimum.
