A butterfly valve consists of body ,stem ,disc , actuator (manual actuator, worm-gear actuator , aerodynamic actuator or electric actuator) , and wafer type butterfly valve can implement the process for turning on turning off and regulating the flow by the circumrotation of stem and disc  that is droved by actuators.
 

1.Simple and compact construction. Small in size and light in weight. Easy transportation, installation and maintenance.
2. Quick 90 degrees on-off operation. Minimized operating torque ,energy saving.
3. Excellent sealing performance with no leakage. Long service life.
4. Wide selection of materials ,applicable for various media..
5. Flow curve tending to straight line. Excellent regulation performance.

 

Q: How do you draw the butterfly valve in the engineering drawing?
Butterfly valve there are many kinds of painting, according to the design institute out of the icon, below we together to understand the icon, which has the butterfly drawing.
Q: Not the cold and hot water shut off valves. The one with a tiny handle and it looks like a T. what does it do? should I mess with it?
Well definitely should not mess with it, especially if you do not know exactly what it is and more important what it controls. If not water, then it could possibly be the shut off for a near by gas appliance. It would help if you described the size and color of the pipe. Maybe you could try to trace it , where does it come from and where does it go to ?
Q: What are the advantages of butterfly valves?
Butterfly valve, also known as shutter valve, its advantages are:A. has a large circulation capacity and is about 1.2 times the same size as two seat valves;
Q: How to use the fire butterfly valve properly?
Clamp and groove type and signal butterfly valve, the first two have what requirements of installation, the operating handle can rotate to open and close the valve installation, signal wiring, mouth down, to prevent water and caused a short circuit three line grounding and alarm line for leakage protection and monitoring of the valve open or closed, general are in line with the alarm valve or flow indicator matched with water, indicating the spacing of not less than 300mm, no other special requirements
Q: Butterfly valve switch direction respectively?
First, if the butterfly valve has been installed on the pipe, you can first see the mark on the handwheel. Second, there is a switch indicator on the general worm gear.
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: Fire signal butterfly valve what role?
Signal butterfly valve should be human action monitoring alarm, once closed, that is, to the system alarmYou ask the two time, I answer two times, you give two points
Q: Butterfly valve D71X-1.6C, DN50, there is no difference between C and no C? What do you mean by "concrete"?
D stands for butterfly valve. 71 represents the clamp type, X represents the sealing surface material, and 16 represents the valve to bear the pressure 1.6MPA, C position is the valve body material code, omitted to represent gray cast iron valve; C represents the valve body material is carbon steel.
Q: D what's the meaning of "one 71x one 1 butterfly"?
According to the provisions of the JB/T 308-2004 valve type programming method:D== butterfly valve7== clip typeLinetype in 1==X== sealing surface material: Rubber-1== pressure rating: 1.0MPa
Q: Butterfly valve is generally used in what position?
It can also be used for switch control of low pressure pipeline medium.
