Sandwich valve is a kind of special device connected to the sealing pipe fittings and connectors, when construction work's role is to cut off the hole sealing equipment and piping within the medium.
Design Pressure grades: 1.0, 1.6, 2.5, 4.0, 6.3, 10.0MPA, ASME Class150, 300, 600, etc。
The inner diameter design is larger than the traditional valve inner diameter, easy to open hole plugging equipment through, the overall thickness is reduced by about 60% compared with the traditional valve, the overall safety factor is increased by 40%, the sealing design uses two-way sealing。
Opening type: Manual type and Hydraulic type。
Sandwich valve is suitable for flammable and explosive, toxic and harmful crude oil, chemical, liquefied petroleum gas, gas, natural gas and other liquids, gas transmission pipeline and urban water supply and heating pipeline with pressure continuous transmission construction operations.
