    Description

    Lugged Knife Gate Valve is specifically engineered for demanding industrial applications involving slurry, pulp, powder, and wastewater. Its compact structure and sharp-edged gate allow it to cut through thick or solid-laden media, making it ideal for industries such as mining, paper, chemical processing, and sewage treatment.

    This knife gate valve features a one-piece body, corrosion-resistant coating, and a stainless steel or alloy blade for long-lasting durability. Its unidirectional shut-off design minimizes pressure loss while ensuring a tight seal, even under tough flow conditions. The non-clogging structure and low operating torque make it highly suitable for systems with limited maintenance access.

    Available with various actuation options—manual handwheel, pneumatic, or electric—the knife gate valve can be adapted for both remote control and manual operation. It supports installation between flanges using wafer or lug-type connections, depending on system requirements.

    As a trusted valve manufacturer in China, we produce all knife gate valves according to international standards such as DIN, and ISO. They are pressure-tested and inspected before shipment to ensure performance and reliability.

    Choose our knife gate valve to ensure smooth, safe, and efficient flow control in harsh industrial environments. It's a reliable solution for handling abrasive and viscous media with ease.

    Frequently Asked Questions

    QWhat is a Lugged Knife Gate Valve used for?
    A Lugged Knife Gate Valve is specifically designed for handling slurry, pulp, powder, and wastewater in demanding industrial environments. It is widely used in mining, paper manufacturing, chemical processing, and sewage treatment industries where thick or solid-laden media must be controlled.
    QWhat is the difference between a lug-type and a wafer-type knife gate valve?
    A lug-type knife gate valve has threaded inserts (lugs) around its body, allowing it to be bolted directly to the pipeline flanges from both sides independently. This makes it suitable for dead-end service. A wafer-type valve is clamped between two flanges and is not suitable for end-of-line service. Both types are available based on system requirements.
    QWhat actuation options are available for this knife gate valve?
    This knife gate valve is available with manual handwheel, pneumatic actuator, and electric actuator options. This flexibility allows it to be used in both manual operation and remote-control automated systems, depending on your process requirements.
    QWhat materials are the main components made from?
    The valve body is made from Ductile Iron, the disc/gate is made from 316 stainless steel, and sealing components use NBR/EPDM and PTFE materials. The stem is made from 2Cr13 stainless steel, and the handwheel is Ductile Iron. These materials ensure corrosion resistance and long service life in harsh environments.
    QWhat international standards does this knife gate valve comply with?
    Our Lugged Knife Gate Valves are manufactured in accordance with international standards including DIN and ISO. Every valve is pressure-tested and thoroughly inspected before shipment to guarantee performance, safety, and reliability in the field.
    QWhat size range is available for the Lugged Knife Gate Valve?
    The Lugged Knife Gate Valve is available in sizes ranging from DN65 to DN300 (and beyond upon request). Each size has specific dimensional parameters including face-to-face length (L), flange outer diameter (D), bolt circle diameter (D1), and overall height (H and H1), as detailed in the dimensions table above.
