knife gate valves can be used for modulating service by modifying the round port to a V-notch port or other shapes. Standard round port valves in the near close position create a crescent shaped opening that can easily be clogged by suspended solids. The addition of a V-port can greatly reduce the change of clogging while also providing a little more linear flow control characteristics.
A V-Port knife gate design, used to limit and control flow, is offered for throttling applications where a more linear flow characteristic is needed.
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.
