Angle Bellows Shut-off Valve

Angle disconnecting valve is suitable for water, steam, oil, gas and corrosive media, widely used in petroleum, chemical, electric power and other systems for installation space is limited or flow direction change requirements of high working conditions. Its structure makes the medium flow direction change 90 °, reducing the use of elbows. Applicable temperature range of -29 ℃ to +550 ℃, depending on the choice of material. The main function is to cut off and regulate the flow, with good sealing and pressure resistance. Valve body commonly used materials are carbon steel, stainless steel, alloy steel, sealing surface can be surfaced carbide, suitable for high temperature and pressure and corrosive environment.

Angle Bellows Shut-off Valve

Subtitle：Zero-leakage globe valve

Our Angle Bellows Globe Valve combines the superior throttling capability of a globe valve with the leak-proof reliability of a bellows seal in a compact 90° design. Designed for critical process applications, it provides gas-tight shutoff in space-constrained installations while optimizing flow dynamics.

Classification:Angle Globe Valve

Working conditions:chemical plant, power plants, Liquefied Natural Gas (LNG), high temperature and pressure

Product Overview

Angle bellows disconnecting valve is a high-performance valve with bellows sealing technology, widely used in petroleum, chemical, electric power, pharmaceutical and natural gas industries, especially for high temperature, high pressure and corrosive media piping system. The valve is suitable for water, steam, oil, gas and some corrosive media, with excellent high temperature, corrosion and pressure resistance.

Angle bellows disconnecting valve can effectively prevent leakage and ensure stable operation of the valve for a long time by replacing the traditional packing seal with bellows seal. Its unique design, compact structure, strong sealing, and can maintain excellent sealing performance under high pressure and high temperature conditions. Product features include flexible opening and closing, easy operation, low fluid resistance, long service life and easy maintenance. The valve is widely used in the cut-off and regulation of fluid media, with efficient and reliable control functions, can ensure the safe and stable operation of the system. Angle bellows disconnecting valve is an indispensable and important valve equipment in industrial piping system.
