Vanne à opercule
This gate valve adopts a wedge or parallel gate disc structure, with a straight-through design that ensures low flow resistance and reliable sealing. Made of cast steel, stainless steel and ductile iron, it is mainly used for on-off control of pipeline media such as water, oil, gas, steam and mild corrosive fluids. Suitable for medium and high-pressure working conditions, it covers sizes from DN15 to DN600 and pressure ratings from PN16 to PN100, with stable opening and closing performance and no jamming. Widely applied in petroleum, chemical, electric power, water treatment and urban pipeline systems, it features simple structure, easy installation and maintenance, and long service life. Strictly tested for pressure and sealing, it effectively cuts off fluid flow, protecting pipeline equipment and ensuring safe and stable operation of the entire system.
Lug type knife gate valve
The Lug Type Knife Gate Valve is a shut‑off valve with a lug‑type body and a knife‑edge gate. It is designed only for ON‑OFF (open/close) service – not for flow regulation. Unlike flanged knife gate valves, the lug‑type body features threaded lugs around the periphery. Bolts are screwed directly into these lugs to connect with pipeline flanges, requiring no nuts. This design allows the valve to be installed at the end of a pipeline or used as an isolation valve, and facilitates removal from one side for maintenance. The valve is suitable for media containing particles or fibers, such as sewage, pulp,…
Manual knife gate valve
The Manual Knife Gate Valve is a shut‑off valve with a handwheel‑direct‑driven mechanism and a knife‑edge gate. It is designed only for ON‑OFF (open/close) service – not for flow regulation. Compared with electric or pneumatic knife gate valves, the manual version requires no external power source, offers simple construction, reliable operation, and low cost. It is particularly suitable for locations without electricity or compressed air, as well as for infrequent operation.
Non rising stem knife gate valve
The Non-Rising Stem Knife Gate Valve is an advanced valve solution designed for applications where space-saving and ease of installation are essential. Unlike traditional rising stem valves, the non-rising stem knife gate valve features a unique stem design that eliminates the need for the stem to rise during operation, making it an ideal choice for confined spaces. This type of valve is commonly used in industries such as wastewater treatment, chemical processing, mining, and pulp and paper, where reliable isolation of slurries, viscous liquids, and other solid-laden fluids is crucial. The sharp-edged gate design ensures smooth operation, even in the...
Rising stem knife gate valve
The Rising Stem Knife Gate Valve is a robust and reliable valve designed for isolating and regulating the flow of abrasive, viscous, or solid-laden media in various industrial applications. Featuring a rising stem design, this valve ensures clear visual indication of the valve position (open or closed) during operation. The sharp-edged knife gate can easily cut through thick, solid, or slurry-type media, making it an ideal solution for applications such as mining, wastewater treatment, and pulp & paper industries. The rising stem mechanism ensures smooth operation and is particularly advantageous when frequent valve position adjustments are required. This valve is...
Slurry knife gate valve
The Slurry Knife Gate Valve is a knife‑edge gate valve specifically designed for handling high‑concentration, solid‑particle‑laden, and fibrous slurry media. It is intended only for ON‑OFF (open/close) service – not for flow regulation. Compared with standard knife gate valves, the slurry knife gate valve features enhanced seat sealing, gate wear resistance, and anti‑clogging flow path design.
Bevel gear knife gate valve
The Bevel Gear Knife Gate Valve is a robust, reliable, and efficient valve designed for applications that require tight shut-off in demanding environments. It utilizes a bevel gear mechanism for smooth and precise operation, making it ideal for larger sizes and high-pressure applications. The bevel gear is particularly beneficial for knife gate valves in sizes DN400 and above, where manual operation can be difficult without a gear mechanism. This type of valve is commonly used in industries such as water treatment, mining, paper manufacturing, and heavy-duty industrial processes, where the valve needs to handle thick fluids, slurries, and other viscous...
Penetration Knife Gate Valve
The Penetration Knife Gate Valve is designed to provide reliable isolation and control in applications involving challenging media, such as slurries, abrasive solids, and viscous fluids. Its specialized penetration design enables the valve's gate to cut through thick, solid-laden media, ensuring tight sealing and efficient operation in demanding environments. Ideal for industries like wastewater treatment, mining, pulp and paper, and chemical processing, this valve offers exceptional performance, even under harsh operating conditions. This valve combines the performance of a traditional knife gate valve with a penetration blade design, allowing it to handle viscous, abrasive, and slurry-type media while maintaining reliable...
Hydraulic Knife Gate Valve
The Hydraulic Knife Gate Valve is a knife‑edge gate valve driven by a hydraulic actuator. It is designed only for ON‑OFF (open/close) service – not for flow regulation. Compared with manual, electric, or pneumatic knife gate valves, the hydraulic version offers high thrust, fast response, remote hydraulic control, and excellent explosion‑proof performance. It is particularly suitable for large diameters, high operating pressures, frequent cycling, and hazardous (explosive) environments.
Pneumatic Knife Gate Valve
The Pneumatic Knife Gate Valve is engineered to handle challenging media, such as abrasive slurries, viscous fluids, and solid-laden liquids, providing reliable shutoff and flow control. With its sharp-edged gate design, this valve can easily slice through thick and solid materials, making it ideal for applications where efficient isolation is required. The valve is pneumatically actuated for quick and precise operation, making it a perfect choice for automated and remote-controlled systems in industries such as wastewater treatment, mining, pulp and paper, and chemical processing. Available in sizes up to DN1200, this valve is built for large-scale operations and is capable...
Flat gate valve without diversion hole
The Flat Gate Valve without Diversion Hole is a robust and reliable solution designed for high-pressure, high-temperature applications in oil and gas pipelines, water distribution, and industrial processes. Featuring a flat gate design and no diversion hole, it ensures minimal pressure drop, tight sealing, and smooth operation, making it ideal for systems requiring full-bore flow and zero leakage.
Flat gate valve with diversion hole
The Flat Gate Valve with Diversion Hole is a parallel‑type gate valve with a slab gate that has a centrally located diversion hole. It is designed only for ON‑OFF (open/close) service – not for flow regulation. The diversion hole equalizes upstream and downstream pressure when the valve is partially opened, significantly reducing operating torque and making the valve easier to operate. This valve is suitable for clean media such as natural gas, crude oil, and refined products, especially in high‑pressure, large‑diameter applications requiring frequent operation.
