The QU model knife gate slurry valve is a bi-directional valve designed for general industrial service applications. The design of the body and seat assures non-clogging shutoff on suspended solids in industries such as:
Wastewater treatment plants
Chemical plants
Food and Beverage etc.
Body:
Wafer style cast monoblock design internally machined up to DN 600 with reinforced ribs in larger diameters for extra body strength. The design has been developed by a new manufacturing process that machines the inside part of the body, allowing more control in the different dimension tolerances. This allows a perfect adjustment of the body-gate-seal, reducing the torque that keeps the tightness and avoiding any build up of solids that would prevent valve from closing.
Gate:
Stainless steel gate, as standard. Gate is polished on both sides for a greater seal between the gate with both packing and seat. Gate is fully guided in the body allowing for bi-directional service.
Materials:
Body:Cast iron(HT200, HT250), Ductile iron(QT450)
Gate:2Cr13, SS304, SS316
Stem:2Cr13, SS304, SS316
Sealing:EPDM, NBR, Viton
Note: Other materials can be supplied on clients' request.
