flange knife gate valve with(pneumatic,electric,hydraulic,lever,chainwheel)
The QB model flange knife gate valve 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.
Materials:
Body:WCB,304,316,316L
Gate:2Cr13, 201, 304, 316,316L
Stem:2Cr13, 304, 316
Sealing:EPDM, NBR, Viton,PTFE,Metal,Stellite
Note: Other materials can be supplied on clients’ request.
