软密封闸阀

暗杆弹性座封闸阀是一种软密封闸阀，采用暗杆设计，闸板完全包覆橡胶。该产品广泛应用于供水、污水、消防、建筑给排水及工业循环水系统。与明杆闸阀相比，暗杆设计所需安装高度更小，特别适用于阀门井或地沟等空间受限的场所。.

The Two-Way Knife Gate Valve is specifically designed for isolation and flow control in systems that handle slurry, viscous liquids, and other media containing solids. It features a robust knife gate that cuts through thick and abrasive materials, ensuring smooth operation even in harsh and challenging environments. This valve is most commonly used in industries such as mining, wastewater treatment, pulp and paper, and chemical processing. Its design allows for bidirectional flow, providing greater versatility in installation and operation.

The Electric Knife Gate Valve is a knife‑edge gate valve driven by an electric actuator, designed only for ON‑OFF (open/close) service – not for flow regulation. It is widely used in automated piping systems in papermaking, wastewater treatment, mining, chemical, and power generation industries for remote shut‑off of media. The sharp knife‑edge gate cuts through hanging fibers, paper, plastic strips, and other materials during closure, preventing clogging.

The Ceramic Knife Gate Valve is designed for applications involving highly abrasive, corrosive, or slurry-type media. The valve features a ceramic-lined seal, providing superior wear and corrosion resistance, making it ideal for industries such as mining, cement, chemical processing, and wastewater treatment. The ceramic seal lining offers excellent protection against abrasive particles and aggressive chemicals. This valve ensures reliable performance and long service life, even in demanding operating conditions. It is suitable for medium to large pipe sizes (typically DN50 to DN800) and handles the toughest flow control tasks in various industries.

The Bonneted Knife Gate Valve is a robust, high-performance valve designed for isolating and controlling the flow of slurries, solids, and other challenging media. It is widely used in industries such as mining, wastewater treatment, pulp and paper, and chemical processing. This valve combines the cutting power of a knife gate with the enhanced sealing capability of a bonneted design, making it ideal for handling aggressive, viscous, or abrasive materials. The bonneted design ensures superior sealing, preventing leakage and protecting the valve internals from harsh external environments. The gate blade is specifically designed to cut through slurries, viscous fluids, and...

The Bonnetless Knife Gate Valve is a high-performance valve designed for isolation applications where efficient cutting of slurries, viscous fluids, and solids is essential. Unlike traditional bonneted knife gate valves, the bonnetless design eliminates the use of a bonnet assembly, offering a more compact and cost-effective solution. This valve is ideal for applications involving low to medium-pressure systems, particularly in industries such as wastewater treatment, mining, pulp and paper, and chemical processing.

The Hard Seal Knife Gate Valve is a knife‑edge gate valve with both the seat and gate sealing faces made of metal (hardfaced with Stellite or other hard alloys). It is designed only for ON‑OFF (open/close) service – not for flow regulation. Compared with soft‑seated (rubber, PTFE) knife gate valves, the hard seal version offers high temperature resistance, high wear resistance, erosion resistance, and long service life.

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,…

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.

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...

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...

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.
