(1) vacuum butterfly valve.A butterfly valve whose working pressure is lower than the atmospheric pressure of standard reactor.
(2) low pressure butterfly valve.Butterfly valves with nominal pressure PN<1.6MPa.
(3) intermediate pressure butterfly valve.Butterfly valves with nominal pressure PN of 2.5- 6.4MPa.
(4) high-pressure butterfly valve.Nominal pressure PN is 10.0--80.0MPa butterfly valve.
(5) extra-high pressure butterfly valve.Butterfly valve with nominal pressure PN>100MPa.
1. Clamp butterfly valve
The disc of the clamp butterfly valve is installed in the diameter direction of the pipe.The valve is fully open.
The wafer butterfly valve is simple in structure, small in size and light in weight.Butterfly valve has elastic seal and metal seal two types of seal.Elastomeric sealing valve, sealing ring can be embedded in the body or attached to the disc around.
2. Flanged butterfly valve
The flanged butterfly valve is a vertical plate structure, and the stem is an integral metal hard seal valve seal ring
It is a composite structure of flexible graphite plate and stainless steel plate.The sealing ring of the soft sealing valve is made of nitrile rubber and installed on the disc.
3. Lug butterfly valve
4. Welding butterfly valve
Welded butterfly valve is a kind of closed type butterfly valve, widely used in building material, metallurgy, mining, power production process such as medium temperature 300 ºC or less on the pipe nominal pressure of 0.1 Mpa, to connect and open/close or adjusting medium quality.
By operating temperature:
(1) high temperature.T > 450 ° C of butterfly valve.
(2) moderate temperature butterfly valve.120 C < t < 450 ºC of butterfly valve.
(3) normal temperature butterfly valve.A 40 C < t < 120 ° C of butterfly valve.
(4) low temperature butterfly valve.A 100 < t < 40 ° C butterfly valve.
(5) ultra-low temperature butterfly valve.A 100 ° C t < butterfly valve.
Center line-type butterfly valve is the advance performance for the butterfly valve, the simple structure, The fluid flow,light weight, easy installation and low driving torque, can be use for cut off medium or regulated flow. The motivation can be according to the customer request,we have the handle, pneumatic and electrically operated valve, the difference situation will be match the different material according the function.
