Stainless Steel Pneumatic Knife Gate Valve

Overview

Stainless Steel Pneumatic Knife Gate Valves are designed for automation in controlling the flow of media in industrial pipelines, particularly in applications involving slurries, fibrous materials, or media with solid particles. The pneumatic actuator provides reliable and efficient remote operation, while the stainless steel construction ensures durability and resistance to corrosion.

Product Features

1. Stainless Steel Construction:
   • Material: The valve body is made from high-quality stainless steel, providing superior resistance to corrosion, rust, and high-temperature conditions.
   • Durability: Ensures long service life in harsh environments, including chemical, petrochemical, and wastewater applications.
2. Pneumatic Actuation:
   • Automation: Equipped with a pneumatic actuator that allows for automated control of the valve. The actuator uses compressed air to open and close the valve quickly and precisely.
   • Efficiency: Reduces the need for manual operation, increasing process efficiency, especially in high-volume and fast-moving operations.
   • Control Options: Supports various control configurations, including double-acting and single-acting (spring return) actuators, to meet different operational needs.
3. Knife Gate Design:
   • Blade: The sharp, knife-like gate is designed to cut through media containing solid particles, slurries, and fibrous materials. It ensures reliable operation even in difficult-to-handle media.
   • Zero Leakage: Provides a tight shutoff to prevent leakage and ensure isolation of the media.
   • Low-Pressure Drop: The valve design minimizes pressure loss when fully open, allowing for smooth flow through the pipeline.
4. Sealing System:
   • Resilient Sealing: Fitted with high-performance seals made of PTFE, EPDM, or other materials depending on the application, providing excellent resistance to abrasion, chemicals, and temperature fluctuations.
   • Self-Cleaning: The design of the knife gate minimizes the buildup of media on the seals, contributing to long-lasting performance and reduced maintenance.
5. Compact and Space-Saving:
   • Slim Profile: The compact, wafer-style design allows for installation in tight spaces, making it suitable for areas with limited room for valve installation.
   • Lightweight: Despite the stainless steel construction, the valve is designed to be lightweight, reducing the overall load on the piping system.
6. Bi-Directional Flow:
   • Flow Control: The valve can be used to control media flow in both directions, offering flexibility in system design and operation.
   • Backflow Prevention: Ensures proper shutoff, preventing backflow in critical systems.

Applications

1. Mining and Minerals Processing:
   • Effective in handling abrasive slurries and other challenging media. The pneumatic operation allows for fast and frequent operation.
2. Pulp and Paper Industry:
   • Suitable for managing pulp and slurry mixtures. The knife gate design prevents clogging and ensures reliable flow control.
3. Wastewater Treatment:
   • Ideal for controlling sludge and waste media. The stainless steel body resists corrosion from harsh chemicals and wastewater.
4. Chemical Processing:
   • Handles corrosive and abrasive chemicals. The pneumatic actuator allows for precise control of media flow in automated systems.
5. Food and Beverage Industry:
   • Used in processing applications where hygiene and corrosion resistance are important. Stainless steel construction ensures compliance with industry standards.
6. Power Generation:
   • Suitable for handling ash slurry, cooling water, and other process media in power plants. The valve’s durable design withstands high pressure and temperature conditions.
