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.

The Comodity Cast Steel Gate Valve is mainly composed of valve body, valve cover, valve wedge, valve seat and valve stem. The two sealing surfaces are wedge-shaped gate valves. The purpose of the wedge is to improve the auxiliary seal load, to achieve both high medium pressure sealing and low medium pressure sealing. The valve body of the wedge valve is provided with a guide mechanism, which can prevent the gate from rotating when the gate is turned on or closed, ensuring that the seal of the gate on the valve seat is accurate accordingly. At the same time, the wedge valve does not rub with the valve seat before turning off, thereby reducing the wear of the cover and effectively extending the service life of the valve.
The DBB Plug Valve is a high-performance fluid control device. It adopts advanced track-guided technology to achieve low-torque opening and closing and zero-leakage sealing. This valve is specially designed for harsh working conditions and is suitable for key fields such as petroleum, chemical industry, power, ships, and long-distance pipelines. It can meet the complex working conditions such as high pressure, high temperature, corrosive media, and frequent operations.

The globe valve is mainly composed of valve body, valve cover, valve disc, valve stem and valve stem nut. The handwheel applies a certain torque on the upper end of the valve stem, and passes the valve stem to the valve petals to move it along the valve stem axis to achieve full or full-closed motion. The force applied by the handwheel can be obsessed with the valve seat to reach the stagnation state. The two-valve petals are designed to enter the top of the medium from the cover of the valve petals. The force force of the medium is the same as the valve closure direction, so the torque of the valve closure is small; The petals, the medium enters the exit of the valve from the inside, and generates a small amount of balance of the pressure of the pressure on both ends of the valve inlet and export, thereby achieving the effect of reduced the valve opening torque. Therefore, globe valve(double disc) is mainly used in high pressure or large-caliber pipelines. At the same time, the globe valve does not rub with the valve seat before the valve is closed, thereby reducing the wear of the cover surface and effectively extending the service life of the valve.
