MANUAL KNIFE GATE VALVE

Body: GGG-40
Gate: AISI 304

Working Principle:

Knife gate valves operate by opening and closing the fluid passage with a knife gate that moves perpendicular to the flow direction between two sealing rings. Knife gate valves are generally preferred for fully open or fully closed operation.

Applications and Sealing:

Knife gate valves are particularly suitable for fluids containing fibers and semi-solid materials, such as applications in the paper industry and wastewater lines. They are available with single-piece or two-piece bodies and elastomer or metal seats, including EPDM, NBR, NR, VITON, PTFE and METAL, providing effective sealing according to the selected configuration.

Knife gate valves can be supplied with handwheel, gearbox, chain wheel, pneumatic actuator, hydraulic actuator or electric actuator operation. Available configurations include rising stem, non-rising stem and through-conduit designs.

Advantages:

Very low flow resistance and smooth flow passage when fully open.
Suitable for flow in both directions.
Can be installed in different positions; however, vertical stem installation with the handwheel on top is generally preferred.
Short face-to-face length even in large nominal sizes.
Economical and readily available.
Easy to maintain.

Fluid Type:

Suitable for semi-solid and fiber-containing fluids.

Actuation:

Handwheel, gearbox, chain wheel, pneumatic actuator, hydraulic actuator or electric actuator.

Nominal Sizes:

DN 50 to DN 1800.

Operating Temperature:

Generally -10 °C to +110 °C, depending on the body and knife material selection.

Body Materials:

GGG-40, GS-C25, RG-5, RG-10, AISI 304, AISI 316.

Gate Materials:

AISI 304, AISI 316.

Connection Types:

Connection type is available according to the selected valve configuration.
