High performance Pneumatic triple eccentric butterfly valve feature
(1) Pneumatic hard seal butterfly valve can ensure a variety of temperature range from ultra-low temperature to ultra-high temperature has a higher sealing performance.
(2) Small fluid resistance, large diameter pneumatic flange butterfly valve fully open when the flow area is large, quick opening and closing time labor saving.
(3) Pneumatic hard seal butterfly valve is often used at room temperature environment, not suitable in high temperature.
(4) Pneumatic hard seal butterfly valve can be used in medium and high pressure, etc.
(5) The actuator of Pneumatic hard seal butterfly valve is divided into single action and double action, single action has normally open type and normally closed type two forms, can be reset to the initial state in emergency (open will close).
(6) Pneumatic hard seal butterfly valve has the advantages of good sealing,long service life.
(7) Pneumatic hard seal butterfly valve has a long service life, but the sealing performance is relatively worse than that of the pneumatic soft sealed butterfly valve.
(8)Pneumatic hard seal butterfly valve is suitable for working conditions of water treatment, environmental protection, light industry, chemical industry and other industries at normal temperature and pressure.Pneumatic hard seal butterfly valve also can be used for heating, gas, oil and other high temperature and high pressure environment.
(9) It can realize miniaturization, mechanical self-locking, and different sealing rings can be replaced to meet different working conditions.

High performance Pneumatic triple eccentric butterfly valve actuator parameter
Double acting actuators: switches are driven by air source, ventilation on, ventilation off, and air source failure to maintain the current position.
Single acting actuator: the switch is only on or off is driven by the air source, and the off or on is based on the spring position.
Single-acting normally closed type: ventilation on, air break off, air source fault off.
Single acting normally open type: ventilation closed, air break open, air source fault open.
Cut off accessories: single solenoid valve, double solenoid valve, limit switch back signal
Regulating accessories: electrical, pneumatic and electrical converters
Reply: also known as limit switch, remote feedback switch (explosion-proof)
Solenoid valve: double-acting two five-way, single-acting two three-way (explosion-proof)
Triplet: it can stabilize the air source, filter and add lubricating oil to the cylinder
Air source treatment accessories: air filter pressure reducing valve, air source treatment triplet
Manual mechanism: Turn handwheel mechanism, open valve and close valve manually
