Introduction: Using crude oil and natural gas as basic raw materials to produce ethylene, propylene, butene, butadiene, benzene, toluene, xylene, naphthalene and other basic chemical raw materials, and then using basic chemical raw materials to produce a variety of organic chemical raw materials and synthetic materials. All kinds of control valves can be used in petrochemical, refining chemical, ethylene, refining and chemical industry, cracking (cracking), hydrogenation, coking, reforming and separation, sulfur recovery and other processes.

Application type: Medium/high pressure direct stroke control valve; Medium/high pressure cut off ball valve; Axial-flow multistage step-down control valve; Labyrinth-type multistage step-down control valve; Multilayer sleeve type multistage pressure relief regulating valve; Eccentric rotary regulating valve; Gate valve; Three eccentric butterfly valves, plastic-lined regulating valves, plastic-lined cut-off valves, etc.
