knife gate valves are a special type of gate valve designed for rugged and reliable applications where a shutoff mechanism is required to handle thick, viscous or abrasive fluids, slurries or powders.

knife gate valves are essential for reliable shutoff of abrasive, viscous or solids-laden fluids. Their rugged construction, coupled with an effective sealing mechanism, makes them suitable for challenging environments where conventional valves may fail. Proper selection, installation and maintenance are essential to ensure optimal performance and longevity.
Durable Construction: This knife-edge gate valve is crafted from carbon steel, ensuring strong and long-lasting performance in hydraulic engineering applications.

Customization Options: Available in a variety of sizes, including customer-requested sizes, this valve can be tailored to meet specific requirements, making it an ideal choice for businesses with unique needs.

Wide Temperature Range: With an operating temperature range of -10 °C to + 200 °C, this valve can handle a wide range of applications from cryogenic to medium-temperature environments.

Compliance with International Standards: Manufactured in accordance with ISO 9001:2015 standards, this valve meets international quality standards, providing assurance for its reliability and performance.

Comprehensive Support: With OEM and ODM support available, businesses can rely on the manufacturer to provide customized solutions, ensuring the valve integrates seamlessly into their operations.

Ceramic valves are suitable for opening and closing of pipes with high hardness particles, such as ash, slag water, pulverized coal, or soft particles but corrosive media. The sealing surface is made of high-grade toughened industrial ceramics. Its chemical stability and hardness are very high.

It has high wear resistance, corrosion resistance and erosion resistance. It also has good thermal insulation, small thermal expansion, high mechanical strength, low starting load, less ash jamming and ash deposit, and long service life Advantage.The solid valve body design can avoid valve body perforation and leakage caused by high-speed medium erosion.
