1. The unique jacket structure design enables the introduction of steam, heat transfer oil or other insulation media, effectively maintaining the fluid temperature inside the pipeline and preventing the medium from solidifying or losing heat.
2. It adopts PTFE (polytetrafluoroethylene) or metal hard sealing valve seats, which are resistant to high temperatures and corrosion, ensuring no leakage during long-term use and meeting the requirements of harsh working conditions.
3. The valve body is forged from high-quality stainless steel or carbon steel and undergoes special heat treatment processes, with a high-temperature resistance of over 300℃, strong pressure-bearing capacity, and suitability for high-pressure pipeline systems.
4. The full-diameter structure design ensures that the fluid passage is consistent with the inner diameter of the pipeline, reducing pressure loss and ensuring smooth fluid flow, suitable for high-viscosity or easily crystallizing fluids.
5. It provides various driving methods such as handles, worm gears, pneumatic or electric, with flexible opening and closing and rapid switching. The modular design is convenient for disassembly and maintenance, reducing usage costs.
6. The surface of the ball is hardened, wear-resistant and corrosion-resistant, and the valve stem has a blowout prevention design, ensuring long-term stable operation, reducing failure rates and replacement frequencies.
7. It is suitable for steam, heat transfer oil, chemical fluids, petroleum, food and other industries, meeting the needs of different media and temperature environments.

When the disc of the lift check valve slides along the vertical center line of the valve body and the medium flows forward, the disc is lifted by the fluid thrust and the medium passes smoothly; When the medium stops flowing or reverse flowing, the valve disc quickly closes under the action of its own gravity and the reverse thrust of the fluid to prevent the medium from flowing back. This valve is usually equipped with a guide sleeve to ensure that the disc remains smooth during lifting and accurately falls back onto the seat.
The Axial Flow Control Valve is a high-performance control valve featuring an advanced structural design. Its straight-through streamlined flow path allows the throttling element to align with the direction of media flow, reducing energy loss and increasing flow capacity by approximately 20%–50%. With a low flow resistance coefficient, robust structure, low maintenance requirements, and high performance, the valve is widely used for the regulation and control of natural gas, crude oil, refined oil, and other non-corrosive gases and liquids.
An energy-saving control valve without external energy supply, used for non-corrosive liquids and gases with a temperature of ≤ 200℃ for differential pressure control devices. The valve opens or closes when the differential pressure increases.
