Description
Benefits:
- Reliable and efficient flow control: The knife gate design of the valve allows for tight sealing, preventing leakage and ensuring efficient flow control in both directions.
- Versatile application: Pneumatic operated knife gate valves are commonly used in various industries, such as wastewater treatment, mining, pulp and paper, chemical processing, and food processing, due to their ability to handle different types of media, including abrasive and viscous materials.
- Easy automation: The pneumatic actuator allows for remote and automated operation, making it ideal for integration into process control systems.
- Low maintenance: The simple design of the valve with minimal moving parts results in low maintenance requirements, reducing downtime and operational costs.
Technical specifications:
- Size range: Typically available in sizes ranging from 2 inches to 48 inches or larger, depending on the manufacturer.
- Pressure rating: Can handle different pressure ratings, ranging from low to high pressure applications, depending on the design and materials of construction.
- Material of construction: Can be made from various materials, including stainless steel, cast iron, carbon steel, and other alloys, to suit different media and process conditions.
- Actuator type: Pneumatic actuators are commonly used, but electric or hydraulic actuators may also be available.
- Operation: Typically operated by a double-acting or spring-return pneumatic actuator, which opens and closes the gate using compressed air or gas.
Applications:
- Wastewater treatment: Pneumatic operated knife gate valves are commonly used in wastewater treatment plants to control the flow of sludge, sewage, and other fluids.
- Mining: These valves are used in mining operations to handle abrasive slurries, tailings, and other challenging media.
- Pulp and paper: They are used in pulp and paper mills for controlling the flow of wood chips, pulp, and chemicals in various stages of the paper-making process.
- Chemical processing: Pneumatic operated knife gate valves are used in chemical processing plants to handle corrosive and abrasive fluids.
- Food processing: They are used in food processing plants to control the flow of food products, such as slurries, sauces, and purees.
