Is a set of production, development, production, assembly, sales, service as one of the science and technology enterprises. It specializes in the research and development of electric valves, pneumatic valves, hydraulic valves, pneumatic actuators and various complete pneumatic valves. The company produces all kinds of pneumatic ball valve, butterfly valve, plug valve, regulating valve, gate valve, globe valve, flat gate valve and other pneumatic devices or valves. (1) Vacuum valve: refers to the valve whose working pressure is lower than the standard atmospheric pressure. (2) Low pressure valve: refers to the valve with nominal pressure PN ≤ 1.6Mpa. (3) Medium pressure valve: refers to the valve with nominal pressure PN of 2.5MPa, 4.0Mpa and 6.4Mpa. (4) High pressure valve: refers to the nominal pressure PN of 10.0MPa to 80.0mpa valve. (5) Ultra high pressure valve: refers to the valve with nominal pressure PN ≥ 100.0mpa. According to the working temperature: (1) ultra low temperature valve: suitable for medium working temperature TLT, - 101 ° C valve. (2) Normal temperature valve: for medium working temperature - 29 ° CLT, TLT, 120 ° C valve. (3) Medium temperature valve: used for medium working temperature of 120 ° CLT, TLT, 425 ° C. (4) High temperature valve: medium working temperature TGT, 425 ℃. According to the driving method: according to the driving mode, it can be divided into automatic valve type, power driven valve type and manual valve type.
