Self-acting Temperature Control Valve is an energy-saving control device that does not require external driving energy. It relies on the temperature of the medium being regulated as the power source and the changes in the medium to automatically adjust according to the preset value. It integrates detection, control and execution functions into one valve and forms an independent instrument control system.
1. The Self-acting Temperature Control Valve is developed by absorbing advanced foreign technology. Key components are imported products, featuring superior performance and reliable quality. It belongs to an energy-saving control system.
2. The Self-acting Temperature Control Valve adopts a stainless steel bellows pressure balance valve core to reduce the force on the valve core when the pressure before and after the valve changes. Moreover, it uses an "O" ring sealed valve stem, which has less friction compared to the packing seal form used in similar products, which is conducive to improving control accuracy.
3. The temperature controllers of the heating type (temperature-closed type) temperature control valve and the cooling type (temperature-open type) temperature control valve can be interchanged, demonstrating strong versatility.
The temperature controller adopts a gas bag type over-temperature protection structure, allowing an over-temperature of 100℃, which is far superior to the spring type over-temperature protection (40℃) mostly used both domestically and internationally.

Operator: It relies on the temperature change of the medium being regulated itself as the power source.
Application range: It is applicable to the temperature control of non-corrosive liquids, gases and vapors in industrial sectors such as petrochemical, metallurgy, chemical engineering, energy, papermaking and light industry, as well as urban centralized heating and heating systems, with a temperature range of +80℃ to +300℃.
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 Lifting Plug Valve adopts a unique dual-action design of lifting and rotation. When opening, it first lifts and then rotates to achieve zero-friction operation. It is particularly suitable for high-pressure difference, easily crystallizing and media containing solid particles. The valve body and the plug are both precisely ground, and the self-cleaning sealing surface design ensures reliable sealing performance under harsh conditions. It is widely used in high-parameter working conditions in the petroleum, chemical and power industries.
Designed specifically for deep cold medium working conditions such as LNG, liquid nitrogen, and liquid oxygen, it adopts special stainless steel or low-temperature alloy valve bodies. Through deep cold treatment, it ensures reliable sealing even in an extreme environment of -196℃. The innovative lateral maintenance port structure allows for quick replacement of the sealing components without disassembling the valve, significantly improving maintenance efficiency. The optimized double eccentric butterfly plate, combined with multi-level metal hard seals, achieves zero leakage and long service life under ultra-low temperature conditions. At the same time, it is equipped with a longened valve stem heat insulation structure, effectively blocking the conduction of cold energy.
