Feature:

1. Knife gate valve opening and closing part is the valve plate, the plate movement direction is perpendicular to the direction of the fluid. Knife gate valve can only be fully open and fully closed, can’t be used for adjusted and the throttle.

2. The valve plate has two sealing surfaces. The two sealing surfaces of the most common gate valve forming the wedge, the wedge angle various according to the valve parameters, usually is 50. Wedge knife gate valve plate can be made into a whole part , called the rigid gate plate; also be made to that can produce small quantities of deformation in order to improve its production process, to make up the sealing surface angle deviations arising during processing, this plate called resilient plate. The seal can only rely on media pressure to seal, which rely on media pressure to ram pressure to the sealing surface of the other side of the seat to ensure the seal, which is self-sealing. 

Product advantages:

1.Stainless steel parts
The inner parts are made of stainless steel to ensure the purity of the medium.

2.Long service life
It overcomes the defect that the traditional valve is easy to rust and corrode, and extends the service life.

3.Reliable, hygienic and anti-corrosion
The inner and outer surface of valve body, cover, battening and connecting plate is sprayed with epoxy resin.

4.Good performance
The valve stem material is stainless steel, the valve stem thread is rolled, the performance is excellent.

5.Simple and compact structure
It is characterized by simple and compact structure, reasonable design, reliable sealing, lightweight material and flexible operation.

6.Easy to install and disassemble
Small volume, smooth passage, small flow resistance, light weight, easy to install, easy to disassemble

Application:

Paper, petrochemical, mining, drainage, food and other industries
