Two-way Sealed Knife Gate Valve

Two-way Sealed Knife Gate Valve

Introduction:

It is a valve with a new structure. Its structure is divided into soft seal and hard seal. The soft seal is composed of movable valve seat and replaceable rubber ring, which can easily replace the damaged seal ring. It can also be made into PTFE seal according to customer requirements, and can well meet the sealing requirements. Completely make up for the previous PTFE difficult to seal and inconvenient processing. The bracket can adopt four column electroplating structure or integral casting forming structure, so that the valve has better firmness and usability. It is a product in the fields of paper making, industry and mining, sewage, chemical industry and food.

Features of two-way sealed knife gate valve:

1. The valve adopts integral design, with small fluid resistance and flexible and convenient operation.
2. The double-plane bearing design is adopted for the screw drive of the two-way sealing knife gate valve, which greatly reduces the transmission friction and makes the valve open easily and smoothly.
3. The seal seat of the knife gate valve adopts a movable seal, and the O-ring preload is used to provide the preload to make the seal seat close to the valve disc, reducing the leakage, and having the automatic compensation function for the wear of the seal pair in long-term use, improving the service life.
4. Fixed guide claw, no groove design, not easy to cause medium accumulation or jamming.
5. The valve seat can choose metal hard seal or soft seal according to the needs of the medium and working conditions: the ram adopts surface chrome plating or ion nitriding treatment to make the ram more wear-resistant and the service life of the sealing surface longer; The soft seal can be PTFE valve seat or reinforced PTFE valve seat or EPDM, NBR, with good sealing performance and corrosion resistance.
6. Wide application range of media: good sealing performance and strong economic practicability, the operation can be manual, pneumatic, electric, and the practical range is very wide.
