pneumatic control  Air Operated Knife Gate Valve

pneumatic gate valve  Introduction

Pneumatic knife gate valve is an automatic control instrument is more complex,by a variety of pneumatic components and body composition. Often used for rapid cutting or opening. It is suitable for medium pipes such as sugar, pulp, sewage, coal slurry, ash,dust, slag and water mixture.It can be used as medium cutting and throttling. The knife gate valve is suitable for horizontal installation and inclined installation. Double acting cylinder:two position control for opening and closing of the gate; single acting cylinder: when the circuit and gas path are cut off or malfunction,the gate automatically opens or closes, that is,normally closed or often opened.

Structural Features

1. Small flow resistance.
2. It is labor-saving when opening and closing.
3. High height and long opening and closing time.
4. Water hammer is not easy to occur.
5. The medium can flow freely to both sides, which is easy to install.
6. The structure length is small.

Installation, Use & Maintenance

1. Before Installation, it's necessary to clean the valve and remove possible defects caused in the transportation process.
2.Check carefully whether marks and the nameplate on the valve meet operating requirements.
3. This valve can be insstalled on pipelines at any angle.
4. This valve shall be fully open or fully closed in running and not be used as a throttle valve, or else its sealing surfaces will be washed and get worn faster.
5. For Long term storage, it shall be stored in a dry and ventilated room whth periodic check to avoid rust.
6. Knocking shall be avoided in the transportation process.

Working Principle

When the cylinder drives the gate to move downwards through the valve's stem, sealing surfaces of the valve's gate and body will be engaged to cut off the channel, namely, closing; the other way around is opening.
