Product Description

classification
structural style
Classification by structure
(1) Central sealed butterfly valve
(2) single eccentric seal coal valve
(3) double eccentric seal butterfly valve
(4) three eccentric seal valve
Sealing surface material
Classification according to the cover material
(1) Soft Sealed Butterfly Valve.
1) the sealing pair consists of non-metallic soft materials for non-metallic soft materials.
2) the sealing pair consists of metallic hard materials for non-metallic soft materials.
(2) metal hard seal butterfly valve. The sealing pair consists of metal hard materials for metal hard materials.
ndustrial valve series

Classification by seal
(1) forced sealing butterfly valve
1) elastic seal butterfly valve. The pressure of the valve seat is extruded by the valve when the valve is closed, and the elasticity of the valve seat or valve plate is generated.
2) external torque seal butterfly valve. The torque generated by the external pressure applied to the valve shaft is generated.
(2) pressurized seal butterfly valve. The seal ratio pressure is generated by the pressure of the sealing element on the seat or valve plate.
(3) automatic seal butterfly valve. The pressure of the seal is automatically produced by the pressure of the medium.

Soft Sealed Butterfly Valve

Working pressure

Classification according to work pressure
(1) the vacuum butterfly valve. Butterfly valve whose working pressure is lower than that of the stack atmosphere.
(2) low pressure butterfly valve. The butterfly valve of the nominal pressure PN<1.6MPa.
(3) medium pressure butterfly valve. The nominal pressure PN is a butterfly valve of 2.5--6.4MPa.
(4) high pressure disc valve. The nominal pressure PN is 10. 0--80.0MPa butterfly valve.
(5) ultra high pressure butterfly valve. The butterfly valve of the nominal pressure PN>100MPa.
working temperature
Classification by working temperature
(1) high temperature butterfly valve. Butterfly valve of t>450 C
(2) medium temperature disc valve. Butterfly valve of 120 C
(3) the butterfly valve at normal temperature. One 40C
(4) low temperature butterfly valve. One 100
(E) ultra low temperature butterfly valve. T< a 100 C butterfly valve
Connection mode
Classification by connection
(1) the pinch butterfly valve
(2) flanged butterfly valve
(3) ear type butterfly valve

(4) welding butterfly valve
