Classification of pneumatic ball valves:

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

Pneumatic ball valve features:

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

According to pressure, can be divided into: high pressure ball valve and low pressure ball valve

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

Low pressure pneumatic ball valve: mainly used in the medium of water and other corrosive pipe!
