○ Applicable media: Suitable for mud, urban sewage treatment, sugar factories, powders, papermaking, pharmaceuticals, chemicals, food 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
○ The steel ring pressure sleeve sealing form is the most common sealing form for knife gate valves
○ Two type new bracket, increasing the strength of the bracket
PTFE limit block ensures that the gate does not come into contact with the valve body, extending the service life of the gate
○ The movable structure of the replaceable rubber sealing ring is mainly achieved by the close contact between the gate and the rubber sealing ring, thus achieving the sealing effect. The main feature of this structure is that the rubber sealing ring is enclosed in the stepped groove on the valve body, and the sealing ring is fastened by a metal pressure ring, so that the sealing ring will not fall off during the sealing process with the gate switch, and the metal pressure ring can be removed to replace the rubber sealing ring at will. This greatly improves the efficiency of valve usage. It is an economically efficient high-performance product.
