First, the scope of use: applicable to negative 50 degrees Celsius to 150 degrees Celsius of various concentrations of aqua king, flow acid, hydrochloric acid, hydrofluoric acid and various organic acids, strong acids, strong oxidants, but also suitable for a variety of concentrations of strong alkali organic solvents and other corrosive gases, liquid medium pipeline use.
Second, the working principle
Globe valve refers to the opening and closing parts (disc) driven by the valve stem and along the axis of the seat to do the lifting of the valve, is a commonly used truncation valve, mainly used to connect or truncate the medium in the pipeline, generally not used for regulating flow. Basic structure: J41 type straight through, J44 type right Angle, J45 type straight flow. The globe valve has the characteristics of compact structure, flexible opening and closing, strong corrosion resistance, short stroke, widely used in chemical industry, petroleum, medicine, food, iron and steel refining, paper making, hydropower, environmental assurance and other corrosive occasions.

Third, product characteristics
◆ Compared with gate valve, the globe valve is simple in structure, convenient in manufacture and maintenance.
◆ Sealing surface is not easy to wear, abrasion, good sealing, long life.
◆ Small free stroke of valve when opening and closing. Shorter opening and closing time, smaller valve height.
● Disc and stem design as a whole structure, compact structure, safe use.
◆ The globe valve has three structural forms: straight through, straight flow, Angle type, among which the straight type is the most commonly used, Angle type can be installed at the corner of the pipeline system, straight flow resistance is the smallest in the globe valve.
◆ Pneumatic and electric devices can be configured according to user needs to meet the needs of remote control and program control replacement parts village materials can be applicable to various media.
