Globe valve, also known as the cut-off valve, is the most widely used type of valve, mainly by the valve body, flap, bonnet, stem and other components. Body, the valve cover for the pressure parts, valve, stem for the internal parts. Shut-off valve is a valve closing the valve (valve) moves along the center line of the valve seat. Depending on the type of movement of the valve disc, the change in valve seat opening is in direct proportion to the valve disc stroke.
Globe valve classification:
Globe valve according to the structure of the valve body is divided into rectangular, direct and DC-type.
1, right angle fluid just change the direction, so that the pressure drop through this valve than the conventional structure of the small valve. More forged body, suitable for smaller through, higher pressure of the globe valve.
2, Straight-through is the most common structure, the media import and export channels in the same direction was 180 & deg ;, but its maximum fluid resistance.
3, DC or Y-shaped shut-off valve, the body of the flow channel and the mainstream into a slash, fluid resistance smaller, and more for solid particles or viscous fluid.
Shut-off valve type:
Press the nominal pressure: vacuum, low pressure, medium pressure, high pressure, high pressure valve;
By working temperature: high temperature, temperature, room temperature, low temperature, ultra-low temperature valves;
By the drive: manual valve, power-driven valve (electromagnetic, pneumatic, hydraulic, electric and all kinds of linkage valve), automatic valves, etc .;
Press body material: cast iron, cast copper, cast steel, carbon steel, titanium, stainless steel valves;
By application department: General valves, power station valves, marine valves, metallurgical valves, pipeline valves, plumbing valves;
By structure: straight-through, angle, DC, etc.;
By the form of connection: internal thread, external thread, flange, welding, the folder, clamp, card sets and other forms;
