Product Description:

Wafer butterfly butterfly plate installed on the diameter of the pipe direction. Cylindrical channels in butterfly valve body, disc disc around the axis of rotation, rotation Angle for 0 ° and 90 °, can have the effect of flow control, when the butterfly plate rotation to 90 °, the maximum opening of the valve. The wafer butterfly valve has simple structure, small volume, light weight, only by a few parts. And only need to rotate 90 ° can rapid opening and closing, simple operation, at the same time, the valve has good flow control characteristics.

Q:How to connect the signal butterfly valve?
The signal butterfly valve should be the surveillance and alarm of human action. Once it is closed, it will alarm the system.Signal butterfly valve wiring method:1, open the switch box cover, according to the electrical control requirements, the cable core line to the corresponding terminal, and sealed cable imports, while the cable fixed, to prevent external force damage when the cable wiring.2, when the valve in the "closed" position, the clockwise rotation of the following relationship to the cam is just touch micro switch cam (you can hear the clicking sound), and then tighten the screw on the cam cam.3, when the valve in the "fully open" position, counterclockwise turn the upper open cam, with the same method to adjust the open cam.4, adjust the limit screw, when the valve in the "full off" or "open" position, should not make the limit screw just at the top of the worm gear limit plane, and should have a certain gap, and then tighten the lock nut on the screw.5, on the cover of the electrical switch box cover, when the valve in the "off" position, the pointer opening indicator to dial "0" scale, and tighten the screws pointer.
Q:Butterfly valve model D373F-16C, ask God answers
D butterfly valve, 3 turbo rotating, 7 pairs clip type, 3 eccentric F PTFE seal, 16 nominal pressure 1.6MPA, C valve body material, carbon steel
Q:Types of butterfly valves
There are clip on butterfly valves and flanged butterfly valves,Manual, pneumatic, electric,
Q:Butterfly valve is the control valve?
The flow characteristics of butterfly valves can be approximately equal percentage characteristics, with the positioner can do adjust, is mainly used in large caliber, straight stroke control valve more than 200 volume weight will be great, it suggests using the butterfly valve.
Q:What is the national standard for clip butterfly valves?
GB/T 12238-2008 "flange and clip connection elastic seal butterfly valve"GB/T 26144-2010 flanged and clip on steel lined fluoroplastic butterfly valvesJB/T 8527-1997 "metal sealed butterfly valve"
Q:What does the model D373H-16C of butterfly valve mean?
D373H-16C said: D type butterfly valve butterfly valve 3 said, said 7 of the turbine, said clip, 3 said the three eccentric (swash plate), 16 C nominal pressure, said carbon steel. In fact, if you want to understand this, to understand the valve 3.07ghz, later met have to be attached to the valve. 3.07ghzModel for valves, valve number indicates valve type valve should normally be that type, drive type, connection type, structural features, nominal pressure, sealing surface material, body material and other factors. Standardization of the valve type of valve design, selection, distribution, provide more convenient. The type of valve types and materials are more and more more models of the preparation of the valve will become more and more complicated. Although the preparation of our valve type unified standard, but gradually can not meet the needs of the valve industry. At present, the valve manufacturer usually adopt a unified numbering; not uniform numbering, the manufacturer can make out no.methods according to their own situation. Unit two unit three unit four unit five unit six unit seven unit
Q:What's the difference between butterfly valves and check valves?
Butterfly valve is manual, only switch function.The check valve is an automatic valve, which prevents backflow of the pipe medium.
Q:What does "D41X-16" mean?
GB case, D is butterfly valve, 4 is flange connection, 1 refers to the midline structure, X is sealed form for three yuan, ethylene propylene rubber seal, and 16 is the pressure of 16 kg.
Q:How many kinds of butterfly valves are there?
What's the score?There are central butterfly valve, double eccentric butterfly valve, three eccentric butterfly valveAnd according to the materialAnd according to the way of connection
Q:How does PLC control butterfly valves?
PLC output signal, access to the butterfly valve actuator or locator, you can control
