Pneumatic knife gate valve is mainly composed of left and right body, U ring, disc, steel nut, valve stem, stents, cylinder and other parts, valve opening and closing to finish by a cylinder.

Pneumatic knife gate valve structure features:

1, the structure of the wafer, small volume, light weight.

2, completely open channel, can prevent the medium inside the valve deposits.

3, newly developed sealing ring, U can ensure good sealing of the valve.

4, outside of the gate seal, it is through the embedded in the body of elastic sealing strip, and with the aid of screw, clamp to adjust.

5, small flow resistance

6, easy installation and maintenance.

Body:HT250

Disc:Stainless Steel

Saet:PTFE

Norminal diameter:DN50-400MM

The correct use of pneumatic knife gate valve cylinder to note:

(1) the load direction must be consistent with the movement direction of the piston rod, lest produce distortions in the piston rod.

(2) the use of filters, pressure reducer, lubricator combination (F - R - E) to adjust the air quality, increase service life.

(3) choose the output is greater than the actual load of the cylinder, so as to avoid danger when air pressure is insufficient.

(4) pay attention to using the environment temperature, cylinder piston ring and the sealing part within the use of material temperature limit within 5 ℃ - + 60 ℃.

(5) have a corrosive gas environment, the piston in the cylinder and the sealing part of the material, usually adopt PTFE.
