○ Applicable media: Suitable for mud, urban sewage treatment, sugar factories, powders, papermaking, pharmaceuticals, chemical and other oil products. Metal seals are suitable for solid media such as coal preparation, slag discharge, mineral powder, slag, and slag in power plants.
○ Steel ring type sealing structure is simple and cost-effective (optional)
○ Standard replaceable sealing ring to protect the valve body, truly achieving no learning cost to replace the sealing ring (optional)
○ PTFE limit block ensures that the gate does not come into contact with the valve body, extending the service life of the gate
○ Two type new bracket, increasing the strength of the bracket
○ Pneumatic multifunctional trapezoidal bracket, sturdy structure, capable of installing travel switches and switch indicator devices
○ The structural design of the replaceable rubber sealing ring mainly relies on the close contact between the gate and the rubber sealing ring to achieve a sealing effect. The main feature of this structure is that the rubber sealing ring is enclosed in the stepped groove on the valve seat, and the sealing ring is locked by a metal spring structure, so that the sealing ring will not fall off during the sealing process with the gate switch. If the sealing ring is damaged, the metal pressure sleeve can be removed and the rubber sealing ring can be replaced at will, greatly improving the efficiency of valve use. It is an economical and effective high-performance product.
○ Automatic cut-off control of high-purity slurry pipelines in the food and pharmaceutical industry
○ Application of acid and alkali resistant pneumatic gate valves in chemical corrosive medium transportation pipelines
○ Corrosion resistant automatic switch device for chlorine containing slurry in papermaking bleaching section
○ Anti rust pneumatic isolation valves for seawater desalination or ship systems
○ Sterility requirements for biopharmaceutical liquid preparation systems - Stainless steel pneumatic gate valves
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 circular sewage pneumatic knife gate valve is mainly sealed with metal between the gate and the sealing surface. This type of valve is best installed horizontally.
