Pneumatic Knife Gate Valve: Features, Application Areas and Selection Guide
- Injap DELCO
The Injap Pintu Pisau Pneumatik is a common device in fluid control systems. In this article, DELCO Valve discusses its features, application areas and selection recommendations.
Working Principle of Pneumatic Knife Gate Valve
The working principle of pneumatic knife gate valve is to control the up and down movement of knife plate through pneumatic actuator, so as to control the flow and stop of fluid or gas in pipeline. When the pneumatic actuator receives a signal from the gas source, the gas in the cylinder pushes the pneumatic actuator and the knife plate moves up and down, thus changing the on-off state in the pipeline.
Features of Pneumatic Knife Gate Valves
- Knife Gate Design: Knife gate cuts through fibers and viscous materials for complex media.
- Fast response: Pneumatic operation responds quickly, suitable for frequent opening and closing conditions.
- Strong durability: the valve body material can be selected from stainless steel, cast iron, etc., to adapt to corrosive or highly abrasive media.
Fields of application
- Paper Industry: Control of the flow of fiber suspensions to ensure line stability.
- Mining and slurry transportation: Handling of highly abrasive slurries or ore slurries.
- Wastewater treatment: control the flow of solid particles and liquid mixtures to optimize system efficiency.
How to Choose the Right Pneumatic Knife Gate Valve
- Material: for example, stainless steel is suitable for corrosive media, cast iron is suitable for common working conditions.
- Actuator type: single-acting actuator is suitable for emergency shutdown scenarios, double-acting is suitable for frequent opening and closing operations.
- Seal design: choose metal or elastic seals suitable for working conditions.
Maintenance and care recommendations
- Check actuator sealing: Ensure proper compressed air supply to prevent leakage.
- Clean the knife gate and valve body: Remove accumulated impurities to avoid clogging or jamming.
- Regular lubrication and inspection: Lubricate the cylinder and knife gate parts, and check whether the valve action is smooth.
