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 normal temperature on the valve?
At normal temperatures are below 120 degrees. A lot of valve sealing surface can only reach 120 degrees
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 is the valve?
valveDefinition of scientific and technical termsValveEnglish Name: valvevalveValve is a control component in the fluid delivery system. It has the functions of closing, adjusting, guiding, preventing reverse flow, stabilizing voltage, shunting or overflow and releasing pressure. Valves used in fluid control systems, from the simplest stop valve to a very complex automatic control system used in a variety of valves, a wide range of varieties and specifications. Valves can be used to control air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow.Definition 1: a device used to control flow in a pipe.Subject: electricity (first level discipline); hydraulic construction (two disciplines)Definition 2: equipment installed in a pressure pipe to control the flow of water.Subject: Water Conservancy Science and Technology (first level discipline); hydraulic construction (two disciplines); gate and hoist (three disciplines)Valve historyThe valve is produced with the flow of the pipe. Human valves have been used for nearly 4000 years. In ancient China from the brine well absorb salt brine, once in a bamboo pipe used in cork valve. In the 1800 BC, the ancient Egyptians used similar wooden cocks to control the distribution of water to build large water conservancy projects to prevent the Nile from overflowing. These are the embryonic form of the valve. The extensive use of industrial valves began only after Watt invented the steam engine. In the early twentieth Century, there were valves of cast steel, wrought steel and forged welded joints.
Q: What valve is the FCV?
It's FCU, Fan, Coil, Unit, fan coil valves
Q: Who knows which kind of water valve is good?
Classification of domestic valves:pipeline valveBathroom valves, kitchen valves, etc faucetsPipeline valve is generally sealed with rubber valve is better, rubber sealed valve sealing performance is very good and durable;Bathroom valves, kitchen valves and other faucets will use copper into the Dian valve, copper valve is not rusty, durable. ,Hope to help you.
Q: What does the RF of the valve mean?
The RF of the valve represents the form of the sealing surface, which means: protrusion.
Q: What's the caliber of the valve 1/4?

Q: What valve is the YQZ45X-16Q?
Specifically, YQ usually is the enterprise code, Z valve, 4 representative flange, 5 representatives of the dark bar, X (soft) rubber seal (gate coated with rubber material), nominal pressure 16 representative (PN) 1.6Mpa, Q on behalf of the valve body is made of ductile cast iron. If you add the valve bore (DN), it will be more detailed.
Q: Which valves are installed in a directional manner?
Very simple answer to your valve, in addition to gate valve and butterfly valve (single line up, first closed), such valves are not directional, and other have
Q: What are the key valve enterprises in China? Mainly in those areas?
Chinese valve is mainly produced in Zhejiang, where Wenzhou, Shanghai there are a lot of Zhejiang valve in Wenzhou, but also Shanghai valve production, many are also Zhejiang boss, the key depends on whether you need what valve valve, the valve may be located in different regions is not the same
