Design feature:

 

1. Simple and compact construction, quick 90 degrees on-off operation. Mininmized operating torque, energy saving.
2. Bubbles-tight sealing with no leakage under the pressure test.
3. The connection of driven part conforms to ISO5211.
4. Wide selection of materials, applicable for various medium.
5. The valve body and disc are accurately machined which results in low operation torque and long service life and reliability.
6. Can be disassembled, material-specific recycling possible.
7.Can be installed at the end of pipe for lugged type butterfly valve.

A:The bushing can assure the correct connection of the upper shaft and the lower shaft, at the same time, it can make sure
the smooth trunning of the shaft.
B:The upper seal made of NBR or fluorine-rubber helps to prevent the pollution from the outside world.
C:Shaft.
D:The taper pin is used to fix the position of the shaft and the disc in order to guarantee the trunning of them
(it has the same material with the disc).
E:The end face seal can be got through the interference fit between the end of the of the disc and the seat.
F:The seal between the disc and the seat can be got through interference fit.
G:Ductile iron, stainless steel and AI-bronze can be taken according to customer's need.
H:There're two types for the body-the wafer type and lug type. On the surface of the body, epoxy powder is painted.
