 5.FAQ

1. How about the Installation of the Wafer Style Butterfly Valve?
A: Butterfly valves are installed by inserting the valve between two flanges using bolts or studs and nuts to hold it all together. This type of installation, of course, makes it impossible to disconnect just one side of the piping system from the valve. That benefit is received using the lug style valve.

 

2. 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.

 

3. 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:Butterfly valve D71X-10 and butterfly D371X-10 what is the difference?
Different structure. The handwheel (or handle) of the D71X-10 is mounted directly on the valve stem, and the D371X-10 is operated by means of a bevel gear in combination with the worm, and the handwheel is mounted on the worm.
Q:What is the effect of nylon coating on butterfly valve plate? Thank you
Mainly media will not be contaminated by rust on the body, you should say that the central soft sealing butterfly valve, the central valve is generally cast steel or cast iron material, so useNylon coatingLining up. There are soft seals, sealing performance is relatively high
Q:Can the inlet and outlet of butterfly valve be reversed? Why? What will happen if the reverse gear is installed?
Our factory butterfly valve has two-way sealing, can be installed, and will not leak. If there is an arrow above the butterfly valve is one-way seal, that is, can not be installed. One way sealing will cause leakage. If you have any other questions, you can bring them up. Let me help you with that
Q:What is the difference between the installation and function of a butterfly valve and butterfly valve?
The principle of the valve gate valve is open and close cases, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle. Gate has two sealing surface, the most commonly used mode gate valve of the two sealing surface forming wedge, wedge angle with valve parameters vary, usually 50, medium temperature is not high when 2 degrees 52. Wedge gate valve can be made into a whole, called the rigid gate; can also be made to produce micro deformation of ram, in order to improve its process of deviation, make up the sealing surface angle in the process, the gate is called the flexible gate. Valve closed, the sealing surface can only rely on medium pressure to seal, that is to rely on medium pressure to the gate sealing surface pressure to the other side of the seat to ensure the sealing surface seal, which is self sealing. Most of the valve is forced seal, that is, when the valve closes, to rely on external force to force the gate to the seat, in order to ensure the sealing surface sealing. Gate valve with the stem along with a straight line of motion, called the lift rod gate valve is also known as the bar gate valve. Usually there is a trapezoidal thread on the lifter. The rotating motion is changed into a straight line through the nut at the top of the valve and the guide groove on the valve body. That is to say, the operating torque is changed into the operating thrust. When opening the valve, when the gate lift height is equal to 1:1 times of the valve path, the passage of the fluid is completely unblocked, but at run time, this position is unable to monitor. In actual use, the top of the stem is used as a sign, i.e., the open position, as its fully open position.Temperature changes appear to consider locking phenomenon, usually open to the vertex position, and then rewind 1/2 1 circle, as a fully open valve position.
Q:anti siphon valve?
anti siphon valves are junk. just install regular valves and put in a backflow preventer on your mainline before all the valves, but right after the shut off vavles.
Q:What's the difference between a clip type turbine butterfly valve and a flanged turbine butterfly valve?
The clip type valve bolts are generally longer, in high temperature conditions, bolt expansion may lead to leakage, so the high temperature conditions are not suitable for large diameter.But for the end and downstream pipeline occasions need to remove the clip on butterfly valve is generally not, because when the downstream flange dismounting clamp down, the valve will fall down, it must do in order to remove the nipple, and the flange type butterfly valve does not exist on the surface of the problem, but the cost will be relatively high.
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:Where is the pcv valve in a 2001 ford focus?
Its on the front of a line that looks like a big black t and it is very hard to notice.
Q:What is the electric butterfly valve? Please, great God!
Therefore, this butterfly valve is the best matching product of automatic fire sprinkler system. The structure characteristics and working principle: the top design electrical device the butterfly valve of the worm and the worm gear driving device, and with the stem straight connecting transmission. In the closed precision electromechanical device, opening mechanical instructions and imported electrical components and parts with rust proof valve.
Q:Which is more expensive, gate valve or butterfly valve?
Same diameter, the same material, with the pressure level, the weight of the gate valve is much heavier than the butterfly valve, about 2 times of the butterfly valve!
