Bevel Gear Non-rising Stem Knife Gate Valve

The QA model knife gate is an uni-directional valve designed for general industrial service applications. The design of the body and seat assures non-clogging shut off on suspended solids in industries such as:

·Wastewater treatment plants

·Chemical plants

·Food and Beverage etc.

Body:

Wafer style cast monoblock with raised face, with reinforced ribs in larger diameters for extra body strength. Internal cast-in gate wedges and guides allows for tighter shut-off. Full port design for greater flow capacity and minimal pressure drop.Internal design avoids any build up of solids that would prevent valve from closing.

Gate:

Stainless steel gate as standard.Gate is polished on both sides to avoid jamming and seat damage.Bottom of the gate edge is machined to a bevel to cut through solids for a tighter seal in the closed position. On request: thickness and/or material of the gate can be changed for higher pressure requirement.

Seat: (resilient)

Unique design that mechanically locks the seat in the internal of the valve body with a stainless steel retainer ring. Standard EPDM also available in different materials such as NBR, Viton,etc.

Packing:

Long-life packing with several layers of braided fibre plus an EPDM o-ring,with an easy access packing gland ensuring a tight seal. Long-life braided packing is available in a wide range of materials.

Stem:

The standard stainless steel stem offers a long corrosion resistant life.

Yoke or actuator support:

Made of EPOXY coated steel (stainless steel available on request).Compact design makes it extremely robust even under the most severe conditions.

Epoxy coating:

The epoxy coating on all JCS cast iron and carbon steel valve bodies and components is electrostatically applied making the valves to be corrosion resistant with a high quality finished surface.
