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.
