Knife-type gate design
The gate of the knife style valve is sharp and can cut off impurities such as fibers and particles to prevent clogging.
Suitable for media with high viscosity and containing solid particles—this is a core advantage of ss knife gate valve and other variants.
Excellent sealing performance
Use elastic sealing ring or metal seal to ensure good sealing effect.
Can be sealed in both directions to meet different working conditions, a key feature valued by knife valve manufacturers and knife edge gate valve manufacturers.
Compact structure
The valve body has a simple design, small size, light weight, and is easy to install and maintain—attributes that make china knife gate valve (also known as knife gate valve manufacturer china products) popular in global markets.
Flexible operation
Supports manual, electric, pneumatic or hydraulic drive to meet a variety of operating needs.
Strong wear resistance
The gate and valve seat are made of wear-resistant materials (such as stainless steel or carbon steel with hard chrome plating) to extend the service life, especially critical for ss knife gate valve used in harsh media.
Low flow resistance design
Full-diameter design, low flow resistance, suitable for large flow conditions—another reason knife style valve is favored in industrial applications.
Diameter range: DN50-DN1200 (or larger).
Pressure level: PN6-PN16 (or higher).
Applicable temperature: -20°C to 150°C (varies depending on the sealing material).
Medium type: mud, sewage, pulp, powder, particles, etc.
Connection method: flange connection, butt clamp connection, in line with international standards (GB, ANSI, DIN ect ).
Efficient cutting: The knife-type gate of stainless steel slide gate valve and pneumatic knife edge gate valve can easily cut fibers and particles to prevent clogging.
Wear-resistant and durable: Stainless steel slide gate valve adopts high-strength materials to adapt to harsh working conditions, ensuring long service life alongside other variants like knife valves pneumatic.
Easy maintenance: Pneumatic knife valve features a simple structure, easy to disassemble and repair—this advantage is also shared by pneumatic knife edge gate valve.
Wide range of applications: Can handle a variety of working conditions with high viscosity and solid media.
Mining industry: used for slurry and tailings transportation, with reliable options available from trusted pneumatic knife gate valve manufacturers and pneumatic knife gate valve suppliers.
Wastewater treatment: suitable for sludge and sewage pipes.
Papermaking industry: processing pulp and wastewater, where pneumatic operated knife gate valve (one of the key types of knife gate valves) offers efficient media handling.
Chemical industry: used for corrosive media or fluids containing particles.
Food industry: suitable for media with high viscosity or containing solid components, with pneumatic operated knife gate valve being a safe and durable option among types of knife gate valves.
