Adjust the pneumatic valve type selection of pneumatic valve

regulating pneumatic valve has a variety of pneumatic valve, commonly used is through single-seat, pass-through two-seater, angular, diaphragm, small flow rate, tee, eccentric rotating, butterfly, sleeve, spherical, etc. In specific choices, to do the following consideration:
( Pneumatic valve core shape of
is mainly based on the selected flow characteristic and factors such as unbalanced force.
( Wear resistance
when fluid medium is suspending liquid containing high concentrations of wear particles, the interior of the pneumatic valve material is hard.
( Corrosion resistant
because of the corrosive medium, try to choose simple structure of pneumatic valve.
( Medium temperature, pressure,
when the medium temperature, high pressure and large, should choose pneumatic valve core and pneumatic valve seat materials by temperature, pressure changes small pneumatic valves. k*Rw':~-
( To prevent flash and cavitation
flash and the cavitation makes in liquid medium. In the process of practical production, flash and cavitation will form the vibration and noise, shorten the service life of pneumatic valves, should prevent when choosing pneumatic valve pneumatic control valve produce flash and cavitation.
