○ Gate material: F55, F532205, SS310, SS316L, SS316, SS304
○ Sealing materials: EPDM, NBR, PTFE,
○ Packing: aramid, high water-based, PTFE, rubber
○ Applicable media: Suitable for solid media such as mud, urban sewage treatment, sugar factories, papermaking, pharmaceuticals, chemical products, etc.
○ Double sealed structure, with a first seal at the packing of the valve, to scrape off dirt on the surface of the gate and prevent debris from flowing up and affecting the opening and closing of the gate in the upper cover.
○ Add a fully sealed upper cover outside the packing to effectively ensure leakage through the packing chamber to the outside. And there is a cleaning port on the upper valve cover, which is a double sealed medium pressure knife gate valve with packing and cover.
○ Unidirectional cut-off control point for sludge or slurry pipelines in sewage treatment plants
○ Equipment for preventing medium backflow and blockage in pulp conveying pipelines in the paper industry
○ Realize one-way sealing and reliable isolation in the tailings discharge system of mines
○ The outlet pipeline of chemical storage tanks needs to be blocked in one direction to prevent backflow pollution
○ The conveying pipeline for thick materials in the food industry meets the hygiene requirement of one-way cutting
One way sealed fully enclosed knife gate valve is a structure in which the gate is fully enclosed in the valve chamber for opening and closing sealing.
Bidirectional self sealing knife gate valve adopts an integral valve body design, with pressure sleeves on both sides of the valve seat to protect the flange surface and increase the service life of the valve.
