Product Description:

1.Manual Wafer Butterfly Valve Description:
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.

2.Main Features of the Manual Wafer Butterfly Valve

1. Small in size and light in weight, easy instillation and maintenance. It can be mounted wherever needed
2. Simple and compact construction, quick 90 degrees on-off operation
3. Minimized operating torque, energy saving
4. Flow curve teeing to straight line, excellent regulation performance
5. Long service life, standing the test of tens of thousands opening/closing operations

5.FAQ
1. What is manual wafer butterfly valve?
A: Wafer style is the more common of the two and is less expensive than the lug style. The wafer style butterfly valve is just about the standard. It ís so common that no one even bothers to use the word "wafer" when ordering a butterfly valve. It is taken for granted that if a butterfly valve is ordered, a wafer style will be received.
2. What is the working principle of manual wafer butterfly valve?
A: A butterfly valve is from a family of valves called quarter-turn valves. In operation, the valve is fully open or closed when the disc is rotated a quarter turn. The "butterfly" is a metal disc mounted on a rod. When the valve is closed, the disc is turned so that it completely blocks off the passageway. When the valve is fully open, the disc is rotated a quarter turn so that it allows an almost unrestricted passage of the fluid. The valve may also be opened incrementally to throttle flow.

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:What's the difference between electric butterfly valve and electric two way valve?
Below we will be specific to understand the electric two way valve and electric butterfly valve of the difference between.Distinguish one: product performance is different, the electric two way valve is for the central air-conditioning fan coil supporting products; and electric butterfly valve and electric control valve is the same species;Difference two: the product function is different, the electric two way valve is automatic adjustment; and the electric butterfly valve is a variety of adjustment methods.Difference three: product classification is different, the electric two way valve body activities are more piston style structure; and butterfly valve structure is diversified, such as sealed form can be divided into soft sealing and hard sealing type of two.
Q:What's the use of fire butterfly valve?
You should ask the signal butterfly valve, butterfly valve in the fire signal system which is a monitoring alarm signal, its purpose is to ensure that the valve has been opened in the daily state, to prevent misuse operation was closed, thus affecting when accidental fire extinguishing. Therefore, it is necessary to set up the signal valve!
Q:What does butterfly valve nps12cl150d373f4-150lb stand for?
NPS (Nominal, Pipe, Size) abbreviation. Refers to the connection (including flanged and welding end) of the nominal diameter, followed by a digital unit is American Standard inches, 12 inches.NPS12 labeling system.CL is the abbreviation for class, and LB150 means the pressure is 150 poundsD stands for butterfly valves3 is expressed in the form of a turbine drive7 means of connection: to clip3 means sealing: 3 eccentricF4: the sealing material is PTFE
Q:What does the model D373H-16C of butterfly valve mean?
For example: Z543H-16C bevel gear flange plate valve, nominal pressure 1.6MPa, the valve body is made of carbon steel valves valve name according to the mode of transmission, connection form, structure, lining material and type name. But here in the name of the content shall be omitted: (1) the connection form: "flange" (2. Structure: a): valve "rod" and "flexible" and "rigid" and "single gate"; B: "straight" stop valve and throttle valve; C: ball "floating" and "one-stop"; D: butterfly valve "vertical plate type"; E: the diaphragm valve "roof"; F: Cock "filler" and "one-stop"; G: check the "one-stop" and "single"; H: "safety valve is not closed. (3) the valve seat sealing surface material in the material name Said. I have just engaged in the valve industry, mainly to do www.ssfmsh.com traps, but also hope that we learn from each other and make progress together
Q:Do you use the straight stem butterfly valve in the fire fighting engineering?
Bar valve bar, did not hear the bar with butterfly valve, ah, there are pairs of folder and hand wheel type bar
Q:Where is the PCV valve?
top of the manifold
Q:What's the difference between a clip on handle butterfly valve and a turbo butterfly valve? Where are they used?
Just drive differently,Handle butterfly valve is generally small caliber, because generally small caliber torque smaller, can be directly opened and closed by handTurbine butterfly gear box drive stem rotation.The selection principle for when the stem torque is greater than 300N.M when used in gear box drive gear box, and use the handwheel control hand wheel force is not greater than 300 nm.
Q:Three eccentric hard sealing butterfly valve, why not fit in the end of the pipe?
The sealing ring will hold up. It does not fit in with the flange end of the pipeline, this addition is the most common and convenient pipeline after purge and easily add pipeline.
Q:My eletric hot water tank started spraying water out the pressure valve?
If you have replaced the TP valve, more than likely there is a heating element shorted to the tank. This will cause continuous heating and high temp/high pressure...good luck.
