Knife gate valve introduction

The knife gate valve is a kind of gate valve, which is a straight-stroke cutting valve. The valve plate head of the knife gate valve has a beveled edge, which has a certain cutting effect on the medium, and is suitable for use in a fiber-containing and solid particle medium and a sewage treatment system. It can be used in manual, pneumatic and electric actuators, and is widely used in process control systems such as papermaking, mining, chemical, and sewage treatment.

 Features

1. The valve adopts integral design, with small fluid resistance and flexible operation.

2. The manual knife gate screw drive adopts the double plane bearing design, which makes the transmission friction force greatly reduced, so that the valve opening is light and smooth.

3. The knife gate seal seat adopts movable seal, and the O-ring pre-tightening provides pre-tightening force to make the seal seat close to the valve flap, and the leakage amount is greatly reduced. The automatic compensation function is improved for the wear of the seal pair in long-term use. The service life.

4, fixed guide claws, no groove design, it is not easy to cause media accumulation or jamming.

5, the valve seat can be selected according to the needs of the medium and working conditions, metal hard seal or soft seal: the ram plate is chrome-plated or ion-nitrided to make the ram more wear-resistant, the sealing surface has a longer service life; soft seal optional PTFE seat or reinforced PTFE seat or EPDM, NBR, good sealing and corrosion resistance.

6, a wide range of media adaptation: good sealing performance and economical and practical, the operation can be manual, pneumatic, electric, practical range is very wide.
