○ Valve body material: WCB, CF8, CF8M
○ Gate material: F55, F532205, SS310, SS316L, SS316, SS304
○ Sealing material: NBR, EPDM
○ Packing: aramid, high water-based, PTFE, rubber, graphite
○ Applicable medium: Suitable for solid media such as mud, urban sewage treatment, sugar factories, papermaking, pharmaceuticals, chemical products, etc
○ Design of U-shaped valve seat sealing ring
○ Split valve body design
○ Equipped with PTFE scraper valve body, effectively preventing fluid upward movement when the valve is opened
○ Two type new bracket, increasing the strength of the bracket
○ No groove design to prevent fluid from staying in the valve chamber
○ DN50-DN550 integrated valve seat sealing ring, larger than DN600 is a 2-inch valve seat sealing ring
○ No groove design, bidirectional sealing structure, adopting a split structure including valve body, gate plate, and U-shaped sealing strip. The left and right sides of the valve body and the bottom of the middle chamber are equipped with grooves and elastic U-shaped sealing strips.
○ When closed, the gate moves downwards, and the bottom edge of the gate contacts the sealing strip, compressing the sealing strip into the groove to achieve sealing between the valve body and the gate.
○ When the gate valve is opened, it moves upward and the bottom edge of the gate valve separates from the sealing strip. The sealing strip bounces up and the groove is flat, which can prevent the medium sediment from accumulating in the groove of the valve body during the use of the knife gate valve.
○ Not easy to block, no residue, easy to clean pipeline, thus effectively improving the sealing effect of knife gate valve and preventing leakage when the valve is closed.
○ Double sealed manual isolation valves are required for the maintenance of ash pipelines in power plants
○ High reliability manual gate valve under bi-directional pressure conditions of mine tailings main pipeline
○ Double sealed safety isolation device for chemical toxic slurry storage tank outlet
○ Cut off point for on-site operation of high-risk medium pipelines in hazardous waste treatment systems
○ Paper making white water recovery pipeline requires manual maintenance valves with zero leakage
The movable structure of replaceable rubber sealing ring is mainly achieved through the close contact between the gate and rubber sealing ring to achieve sealing effect.
No groove design, bidirectional sealing structure, adopting an integral structure including valve body, gate plate, and U-shaped sealing strip.
The structural design of replaceable rubber sealing rings mainly relies on the close contact between the gate and the rubber sealing ring to achieve a sealing effect.
