Hard seal butterfly worm gear pneumatic valve to the advantages

if after the temporary use of sealing performance, hard seal turbine control pneumatic valve is equipped with sealed adjusting device. Adjustable disc plate sealing ring to be near pneumatic valve seat can restore original sealing performance, greatly improve the service life.
hard seal butterfly worm gear pneumatic valve to the advantages:
forming by high precision machining, hard seal turbine control pneumatic valve seal is to use hard and soft layers of metal layer. Flush mounted on the disc plate with pneumatic valve seat, with metal sealing and elastic sealing the dual advantages of no matter under the condition of low temperature and high temperature, has good sealing property.
have the close tight sealing function. Using three-dimensional structure of eccentric pneumatic seat and disc plate almost no friction.
flexible operation, energy saving, convenient and not affected by medium pressure high, low, unique structure. Reliable sealing performance, long service life.
