Instrument Valve Group

Instrument valve group refers to a needle valve composed of multiple instrument valves, generally including two valve group, three valve group, five valve group, etc. It is mainly used for various complex multi pipeline equipment, and controls the flow rate, pressure, direction and other functions of the equipment through multiple control units of one valve. The instrument valve group is suitable for various working conditions such as temperature: -20 ℃~+440 ℃ -70 ℃~-240 ℃ ≤ 540 ℃ ≤ 570 ℃. The valve body materials include A105, 304, 304L, 316, 316L, WC6, WC9, etc. The instrument valve group produced by Shanghai Meiyanyi Pump Valve is widely used in the semiconductor industry for precise adjustment of nitrogen purging volume and control of air flow. It has the advantages of easy installation and disassembly, tight connection, high fire prevention, explosion prevention and pressure resistance, and good sealing performance.
