○ Gate material: F55, F532205, SS310, SS316L, SS316, SS304
○ Sealing material: EPDM
○ Packing: aramid, high water-based, PTFE, rubber, graphite
○ Applicable medium: Suitable for power plants, slag discharge and other fields
○ The bottom of the gate is designed with a diagonal angle
○ Wedges on both sides of the valve body
○ The above two characteristics ensure that the gate plate plays a limiting role when it is closed, effectively increasing the service life of the sealing ring
○ Two type new bracket, increasing the strength of the bracket
○ The circular sewage pneumatic knife gate valve is sealed between the gate and the sealing surface, mainly with metal sealing. This type of valve is best installed horizontally. It is widely used in power plants and other fields due to its advantages of no material jamming, sturdy structure, and long service life.
○ Remote automatic discharge control of sludge discharge pipeline in sewage treatment plant
○ Power plant desulfurization and denitrification system slurry pipeline regular dredging and cutting device
○ Chemical reaction kettle or storage tank bottom high concentration medium slag discharge isolation valve
○ Quick opening and closing point for the discharge outlet of pulp or white water recovery system in the paper industry
○ Food and pharmaceutical cleaning systems require residue free and easy to clean discharge control valves
Bidirectional sealed knife gate valve, with no groove design, adopts a split structure, and an improved polyurethane lined valve seat sealing ring fully protects the valve body from medium erosion
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.
