Valve manufacturers to introduce you to the application of the valve several major areas: 1, Petroleum equipment Valves
(1) refining equipment. Most of the valves used in refinery equipment are pipe valves, mainly for gate valves, globe valves, check valves, safety valves, ball valves, butterfly valves, steam traps, of which, gate valve requirements accounted for about 80% of the total number of valves, (valves accounted for 3% to 5% of total equipment investment);
(2) Chemical fiber device. Chemical fiber products are mainly polyester, acrylic, Vinylon three categories. Its required valve ball valve, jacket valve (jacket ball valve, jacket gate valve, jacket cut-off valve);
(3) Acrylic clear device. The device generally needs the size of the valve produced, mainly for the gate valve, globe valve, check valve, ball valve, steam trap, needle-type globe valve, plug valve, which, the gate valve accounted for about 75% of the total valve;
(4) Ammonia plant. Because the ammonia source and purification methods are different, the process is different, the required valve technical functions are also different. At present, the domestic ammonia plant mainly needs gate valve, globe valve, check valve, steam trap, butterfly valve, ball valve, diaphragm valve, regulating valve, needle valve, safety valve, high temperature and low temperature valve.
