Pneumatic Knife Gate Valve

[Essential information]
        Pneumatic knife gate valve is one of the most important varieties of production process control valve. With the solenoid valve, switch control can be completed, and the electric valve positioner can also be used to complete the adjustment control. Users can choose according to actual needs. The main body adopts cast steel, stainless steel and so on. It is particularly suitable for the paper industry, chemical industry, coal, sewage, sugar and other industries.

[Valve features]
1, the valve adopts integral design, the fluid resistance is small, flexible and convenient operation.
2, manual knife gate valve, screw drive using double plane bearing design, making the transmission friction greatly reduced, so that the valve open easy and smooth.
3, knife gate valve sealing seat by movable sealing, and the use of O ring preload preload to provide sealing seat close to the valve, the amount of leakage is greatly reduced, in the long-term use of seal pair with automatic wear compensation to improve the service life.
4, fixed guide claw, no groove design, not easy to cause dielectric accumulation or blocking.
5, valve seat can according to the needs of medium and condition, choose the metal seal or soft sealing gate: chrome or by surface ion nitriding treatment, the gate sealing surface more wear and longer service life; soft sealing valve seat or optional PTFE enhanced PTFE seat or three yuan, Ding Qing rubber, good sealing, corrosion resistance.
6, medium wide range of adaptation: good sealing performance and economic, practical, operation can be manual, pneumatic, electric, practical range is very wide.

[Adaptive condition]
       Knife type pneumatic valve is the important executive mechanism of industrial automation control system, remote centralized control can meet the needs of computer program; now widely used in petroleum, chemical industry, gas equipment, nuclear power equipment, water treatment, air conditioning, iron and steel metallurgy, industrial furnace, canned equipment, brewing equipment, drying equipment, vacuum equipment, surface treatment, bio pharmaceutical, food machinery, textile, papermaking and other industries, the preferred product is construction of national defense construction, science and technology.
