1. Manual Wafer Butterfly Valve Description

A butterfly valve is a valve which can be used for isolating or regulating flow. The closing mechanism takes the form of a disk. Operation is similar to that of a ball valve, which allows for quick shut off. Butterfly valves are generally favored because they are lower in cost to other valve designs as well as being lighter in weight, meaning less support is required. The disc is positioned in the center of the pipe, passing through the disc is a rod connected to an actuator on the outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow. Unlike a ball valve, the disc is always present within the flow, therefore a pressure drop is always induced in the flow, regardless of valve position.

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. 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.

 

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:What is the main function of the valve?
Acting on switch control, flow regulation, remote control, etc.
Q:Ketem valve relative to other valve companies in the industry what are the advantages?
Floating seal: electric drive, electric ball valve flange connection floating ball straight, seal form with seal, the sealing surface of the valve seat material for hard alloy, nominal pressure PN16~PN63, nominal size DN15~DN200, suitable temperature of -28~500, the valve body is made of carbon steel or stainless steel. As a result of the use of hard sealing (metal seal), this valve is particularly suitable for particles, solids, slurry and other medium and high temperature and high pressure pipelines.
Q:What's the meaning of the "single valve"?
There are nuts, plants, flush three parts. The pipeline steel or steel ingot forging molding machine fittings, connection form the socket welding and threaded, socket welding steel pipe is inserted into the socket is in welding, so called "socket joint, thread connection pipe is screwed in the screw through connection.
Q:How to carry out the valve strength test and air tightness test?
Refer to the GB/T13927 or ISO5208 standards and need to pass it to you
Q:Excuse me American Standard pressure test valve GB standards are much ~ is how much valve pressure can play much pressure? Thank you
The standard is different, the test is not the same, what kind of valve you, a domestic valve only do stress testing, in fact, the pressure can generally be guaranteed, many are bad at high temperature or life testing above
Q:A kitchen, 2 bathrooms, in addition to the toilet, toilet (only cold water), the rest need hot and cold water supply, and hot water by solar water heaters and gas water heater selection. The kitchen is mainly a sink, each toilet for toilet, shower, washbasin, separate cold water faucet. I don't know how many metal materials I'll use now Thank youThe waterways are all dark!
PP-R ball valve (cold hot water pipe valve): solar water heater 2, gas water heater 2, 2 hot water pipe switching with 1, indoor main water supply valve 1, 2 toilet water supply valve 1, total 8.Eight character valve (angle valve): kitchen, dishes, basins 2, toilet, toilet 2, wash basin 4, total 8.Other: shower water mixing valve 2, water washing machine 2, 2 washbasin faucet, basin faucet dish 1.The water supply of solar water heater and gas water heater is calculated according to the hard connection of PP-R pipe.
Q:What do O and S mean on the valve?
Generally used in process valves, operating conditions required to open and close, especially in the case of pneumatic actuators installed, the loss of power and gas supply valve when the state
Q:Standard and specification for pressure test of valves
(11) when the valve with drive device is tested and its tightness is tested, the sealing test shall be carried out by using the driving device to close the valve. For manual drive units, seal test shall also be done with the actuating closing valve.(12) the by-pass valve installed on the main valve after the strength test and the sealing test. The strength and tightness test of the main valve is carried out. The main valve should be opened when the closing member is opened.(13) iron valve strength test, the application of Pratia tapping valve and valve cover, check whether there is any leakage.(14) the valve test, in addition to the provisions of the plug valve to allow sealing surface oiling, other valves are not allowed in the sealing surface of the oil test.(15) when the valve pressure test, the blind plate on the valve pressure should not be too large, so as to avoid deformation of the valve, affecting the test results (cast iron valve if pressed too tight, will be damaged).(16) after the valve test pressure, should promptly remove the water and clean the valve, should also be prepared for the test record.
Q:Valve difference
That depends on where it is used! No one knows how many kinds of valves. If you have water, you can use gas, food, and so on.
Q:What does the valve "4" mean?
An inch of eight points, home tap, valve is generally 4 points
