Lockup device, manual operation, in order to prevent misoperation, valve can be equipped with padlock device.
Anti-static structure, when a fire break out, the metal seal forms to prevent large leakage of media.
Valve body and stem can finish emergency injection seal, through the grease injection valve, the stop-leak compound can achieve a short-time
seal, therefore buying time handling the scene.

The Bellows Seal Gate Valve is a high-performance valve designed to ensure sealing integrity and prevent medium leakage. It utilizes bellows seal technology to effectively block fluid leaks that could cause environmental pollution or safety hazards. This valve is suitable for use in steam, thermal oil systems, heat exchangers, and other high-temperature, high-pressure fluid control applications. Its compact structure and easy maintenance offer long-term reliable sealing performance.
The Power Station Gate Valve is mainly suitable for the pipelines of various systems of thermal power station, cutting or connecting the pipeline medium. Compared with other valve products, the power station gate valve is characterized by high temperature and high pressure. It is counted as a unique and closely sealed structure. The higher the pressure, the more reliable the sealing performance. Due to the characteristics of performance and technical characteristics and working conditions, the product has also formed the characteristics of other products that cannot be replaced. This type of valve should generally be installed horizontally in the pipeline. The power station gate valve has the design characteristics of ordinary wedge-type gate valves. The valve body has a guide mechanism to prevent rotation when the gate is turned on or closed to ensure that the seal of the gate on the valve seat is correspondingly accurate. 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 cryogenic butterfly body can be provided in two structural forms, namely flange connection and butt. welding connection (both with inspection ports). The body with inspection ports can replace the valve internals online, making maintenance work extremely simple, which is conducive to the rational use of resources and saving maintenance costs. The extended valve cover + drip tray design ensures that the temperature at the stuffing box is above zero degrees, so that the connection between the stuffing and the stem will not freeze and lock. Through the use of three-dimensional simulation optimization design, effective control of material changes under cryogenic conditions, selection of high-quality materials and effective processing technology to meet the stable performance of materials under cryogenic conditions. This series of valves has good sealing performance, high reliability, light weight, compact structure, and no need toworry about abnormal increase in valve cavity pressure. lt isan ideal valve for conveying cryogenic media and can bewidely used in cryogenic conditions in liquefied natural gas,aerospace and other fields.
