Pneumatic high-performance double eccentric butterfly valve, bidirectional sealing, zero leakage, can simply and quickly replace the valve seat, suitable for liquid, gas, seawater and other media, pressure PN16-PN40, Class 150-300, diameter DN50-1200, material: WCB carbon steel, SS304, SS316, SS316L, 310S, 2205, 2507 duplex steel.

The pneumatic high-performance double eccentric butterfly valve adopts a double eccentric structure design. The arc sealing surface design of the valve plate enables the valve plate to quickly separate from the valve seat when opened, reducing the friction of the sealing surface. When the valve plate is closed, it has excellent sealing performance. Valve seat design: The valve seat of the double eccentric butterfly valve is locked on the valve body by the cover, and the cover is fixed on the valve body by bolts. The sealed valve seat is fixed between the cover and the valve body, and the valve seat is adjustable.

Replaceable valve seat: The replacement of the valve seat sealing ring is simple. Rotate the valve plate to the closed position, remove the retaining ring cover, take out the old valve seat, insert the new valve seat into the groove of the valve body, then press the cover against the valve seat and lock the cover with bolts. The process is completed. The entire process is simple and fast, and does not affect components such as the butterfly plate and valve stem. Under normal circumstances, the valve seat sealing ring can be replaced every 5 minutes.

Travel stopper: The internal travel limit design can prevent the butterfly plate from overturning, thereby extending the service life of the valve seat and reducing the possibility of valve seat damage.

Pneumatic actuators come in two types: double-acting and single-acting (spring return), as well as rack and pinion type and fork type.

The rack and pinion type cylinder housing is generally formed by die-casting aluminum alloy, which is light in weight and beautiful in appearance. The casing of the fork-type cylinder is generally made of cast iron. In addition, there are stainless steel and steel casings available for customers to choose from.

Pneumatic accessories: positioners, limit switches, filter pressure reducers, solenoid valves, HVSD hand-operated mechanisms.
