Ball valve has O ball valve and V ball valve.O-ball valve adopts floating structure, ball core for precision castings, the appearance of hard chromium plating treatment, seat reinforced ptfe material, flow mouth and pipe diameter is the same, circulation capacity is great, flow resistance is very small, no leakage when closed, generally used as on-off valve, especially suitable for high viscosity, containing fiber, granular media;V-type ball valve with fixed structure, the ball core is opened with v-notch, can achieve proportional adjustment, flow characteristics for approximately equal percentage.

According to different process equipment can choose pneumatic or electric, respectively composed of pneumatic ball valve and electric ball valve, pneumatic ball valve such as to achieve proportional adjustment must be equipped with valve positioner, electric ball valve such as to achieve proportional adjustment must be selected electronic electric actuator or with servo amplifier, etc.

From the material, can be divided into: carbon steel ball valve, stainless steel 304 ball valve,316 ball valve and copper ball valve

In application, can be divided into: high pressure ball valve and low pressure ball valve

High pressure ball valve: mainly used in oil, natural gas, hydraulic oil, construction machinery and other industries

Low pressure ball valve: mainly used in the medium for water and other non-corrosive pipeline!
