Stainless Steel Non-Rising Stem Knife Gate Valve

Overview

A stainless steel non-rising stem knife gate valve is designed for handling media with solids, slurry, and fibrous materials in corrosive environments. The non-rising stem design makes it compact and suitable for installations where vertical space is limited, while the stainless steel construction ensures high durability and resistance to corrosion.

Product Features:

1. Non-Rising Stem Design:
   • The valve uses a non-rising stem configuration, meaning that the stem does not move vertically when the valve is opened or closed. This makes it ideal for areas with limited space above the valve, as the stem remains inside the valve body during operation.
2. Stainless Steel Construction:
   • The valve body, gate, and internal components are made of corrosion-resistant stainless steel, making it suitable for applications in aggressive and corrosive environments such as chemical processing, marine, and wastewater treatment.
3. Knife-Edge Gate:
   • The sharp-edged gate can cut through media with suspended solids or fibrous materials, preventing blockages and ensuring smooth operation in challenging flow conditions. This design is particularly useful in industries such as pulp and paper, mining, and wastewater.
4. Compact and Space-Saving:
   • The non-rising stem design allows for a more compact installation, reducing the overall height of the valve and making it suitable for tight spaces or areas with height restrictions.
5. Bidirectional Sealing:
   • The valve provides reliable sealing in both directions, ensuring no leakage in either flow direction. This is important in applications where isolation of media is critical.
6. Low Maintenance:
   • The simple design of the knife gate valve with fewer moving parts results in low maintenance requirements. The stainless steel components resist corrosion, reducing wear and extending the valve’s service life.
7. Available in Manual, Electric, and Pneumatic Actuators:
   • The valve can be operated manually, or fitted with electric or pneumatic actuators for automated control, depending on the application’s needs.
8. Resistant to Corrosive Media:
   • Due to its stainless steel construction, the valve can handle corrosive liquids and gases, making it suitable for industries like chemical processing, food and beverage, pharmaceuticals, and wastewater treatment.
9. Smooth Operation in Tough Media:
   • The non-rising stem mechanism combined with a knife-edge gate ensures that the valve performs well even in media with heavy slurry, solids, or fibrous content.

Applications

1. Wastewater Treatment Plants:
   • Ideal for controlling the flow of wastewater, sludge, and slurry, particularly in corrosive environments or systems with limited space.
2. Pulp and Paper Industry:
   • Efficiently handles fibrous materials and pulp, ensuring smooth flow without clogging or blockages in processing pipelines.
3. Mining and Mineral Processing:
   • Suitable for controlling the flow of abrasive slurry and other mining materials where high durability and resistance to corrosion are required.
4. Chemical Processing:
   • Designed for applications involving corrosive chemicals, acids, and aggressive media. The stainless steel body offers enhanced protection in these challenging environments.
5. Food and Beverage Industry:
   • Can be used in applications where hygiene, durability, and resistance to corrosive cleaning agents are essential.
6. Power Generation:
   • Handles ash, slurry, and other solid-laden fluids in power plants, with the non-rising stem design ensuring space-saving installation.

Advantages

• Space-Saving Design:
  The non-rising stem design reduces the overall height of the valve, making it ideal for installations where vertical space is limited.
• Corrosion Resistance:
  Stainless steel construction provides excellent resistance to corrosion and ensures long service life in harsh environments.
• Effective in Challenging Media:
  The sharp-edged gate can easily cut through thick media, fibrous materials, or slurry, ensuring smooth operation even in difficult flow conditions.
• Low Maintenance:
  With fewer moving parts and corrosion-resistant materials, the valve requires minimal maintenance, reducing downtime and operational costs.
• Versatile Actuation Options:
  The valve can be operated manually or automated using electric or pneumatic actuators, offering flexibility for various industrial processes.

The stainless steel non-rising stem knife gate valve is a durable and reliable solution for industries requiring effective flow control in challenging media such as slurry, solids, or corrosive chemicals. Its space-saving design, combined with the corrosion-resistant properties of stainless steel, makes it an ideal choice for various industrial applications where performance and longevity are crucial.
