Have you known these classifications of stainless steel ball valves? Let Junkai Valve introduce to you below!
1. According to the structural classification, ball valves can be divided into O-type ball valves and V-type ball valves: O-type ball valves use floating balls in structure, the ball core is precision casting, the surface is plated with hard chrome, and the valve seat is made of reinforced PTFE material. The flow opening is the same as the pipe caliber, with large flow capacity, very small flow resistance, and no leakage when closed. It is usually used as an on-off valve; the V-shaped ball valve adopts a fixed structure, and the ball core has a V-shaped cutout, which can realize proportional adjustment. , the flow characteristics are approximately equal percentages.
2. According to the classification of process equipment, the ball valve can be pneumatic or electric, which are composed of pneumatic ball valve and electric ball valve respectively: if the pneumatic ball valve needs to achieve proportional adjustment, it must be equipped with a valve positioner; if the electric ball valve wants to achieve proportional adjustment, it must choose electronic ball valve Type electric actuator or with servo amplifier, etc.
3. According to material classification, ball valves can be divided into carbon steel ball valves, stainless steel 304 ball valves, 316 ball valves and copper ball valves.
4. According to application classification, ball valves can be divided into high-pressure ball valves and low-pressure ball valves: high-pressure ball valves are often used in industries such as petroleum, natural gas, hydraulic oil, and construction machinery; low-pressure ball valves are often used in corrosive pipelines where the medium is water.
The above is the introduction of different classifications of stainless steel ball valves.
