Monoblock Slurry Valve 1.Monoblock body Design. 2.Bi-directional flow. 3.Zero Leakage.

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.

Packing:
Long-life braided packing is available in a wide range of materials.

Stem:
DN40-DN400: Non-rising Stem. DN500 and larger:Rising stem.

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 product.

Actuator:
Manual: Handwheel,Bevel Gear,Chainwheel,Lever

Automatic:Double acting pneumatic, single acting pneumatic, electric, hydraulic, electro-hudraylic etc.

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.
