Our hard seal wedge gate valve is engineered for critical service applications requiring metal-to-metal sealing without elastomers. Featuring a precision-machined solid wedge design, it delivers bubble-tight shutoff in high-pressure, high-temperature, and abrasive media applications where soft-seated valves fail prematurely.

The Forged Steel Gate Valve is a high-performance solution designed for extreme pressure and temperature applications in oil and gas, petrochemical, and power generation industries. Manufactured through precision forging, it offers superior strength, durability, and leak-tight sealing, making it ideal for critical isolation tasks in harsh environments. This valve is strictly for on/off service and not suitable for throttling.

The Self-actuated Forged Steel Gate Valve is a high-performance, automated solution designed for critical isolation tasks in oil and gas, petrochemical, and power generation industries. Combining the strength of forged steel construction with self-actuated operation, it ensures reliable, energy-efficient performance in high-pressure and high-temperature environments. This valve is strictly for on/off service and not suitable for throttling.

The Bellows Type Forged Steel Gate Valve is a high-performance solution designed for critical isolation tasks in applications requiring zero leakage and high reliability. Featuring a forged steel body and a bellows seal, it ensures exceptional sealing performance in high-pressure, high-temperature, and hazardous environments. This valve is strictly for on/off service and not suitable for throttling.

In summary, our DN15-DN50 forged steel cryogenic gate valve delivers reliable, leak-proof performance for compact cryogenic systems, featuring space-saving design, -196°C operation, and Class VI sealing - all built with durable ASTM A350 forged steel for long service life in LNG, lab, and gas applications.

The Non‑rising Stem Resilient Seated Gate Valve is a soft‑sealing gate valve with a non‑rising stem and a fully rubber‑encapsulated gate. It is widely used in water supply, sewage, fire protection, building water supply & drainage, and industrial recirculating water systems. Compared with rising stem gate valves, the non‑rising stem design requires less installation height, making it ideal for confined spaces such as valve pits or trenches.

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.
