The QB model wafer 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.

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.
