Pneumatic classification and characteristics of three type pneumatic ball valve 2)

the classification and features of the three type pneumatic ball valve pneumatic:
pneumatic valves, pneumatic type O pneumatic ball valve and v-shaped ball. O floating ball structure, precision casting, ball core surface hard chromium plating, teflon, the same flow and pipe diameter, flow capacity is big, pneumatic seat materials, little flow resistance, sealed, without leakage switch do you usually do pneumatic valve is especially suitable for high viscosity, fiber, granular media; V-shaped ball has a fixed structure, pneumatic valve, and then open v-notch ball feet can be adjusted, in order to realize the scale, the flow characteristics of similar percentage.
according to the technological equipment of pneumatic or electric actuators, pneumatic valves, pneumatic and electric pneumatic valve components, pneumatic pneumatic valve, including the selection of different, such as assigned to to achieve proportional control pneumatic valve positioner, the electro-hydraulic proportional control pneumatic valve should be through the following ways to realize electronic choose electric actuator or servo amplifier.
from the material, can be divided into: carbon steel ball pneumatic valve, pneumatic valve, stainless steel ball and copper ball, pneumatic valve and application can be divided into: high and low pressure pneumatic ball valve pneumatic high-pressure pneumatic valve, mainly in the oil, gas, hydraulic oil, engineering machinery, such as the low pressure pneumatic pneumatic valve: mainly used in the corrosive medium of tap water pipe.
