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 are mine valves?: You want to see what works on the use of what media, in the choice of what type of valve is more appropriate. Shanghai HuquanValve manufacturers, veteran enterprises, trustworthy.

Q:The difference between fire general valve and fire fighting special valve: Fire fighting valves are mainly signal valves and alarm valves and water indicators, etc., other gate valves, butterfly valves, pressure relief valves and filters are common valves.

Q:How does the valve close?: Rotate it, turn it clockwise. Spherical valve, then hit a cross shaped on the line.Valve (Famen) 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.

Q:Which valves are used in the power station?: Power gate valve, also known as power station valve, is mainly used in various pipelines of fire power plants, cutting off or connecting pipeline medium.Applicable medium: non corrosive media such as water and steam. Compared with other valve products, the valve is characterized by high temperature and high pressure and unique self sealing design. The higher the pressure, the more reliable the seal is. Because of its performance, technical characteristics and special working conditions, the products can not be replaced by other products.Compared with other valve products, the gate valve of the power station is characterized by high temperature and high pressure. If only the pressure is lower than that of the universal valve, the temperature is lower than that of the general valve. Because of its performance, technical characteristics and special working conditions, the products can not be replaced by other products.

Q:How does the valve rust die?: The treatment of valve rust is as follows:1, use corner grinder cut off valve, and then a small mill grinding wheel cutting residual film cut pipe installed in the screw part, when the attention of cutting depth.2, with the amount of hydrochloric acid corrosion and rust of the valve, until the rust completely removed, rinse with water.3, on the newly purchased valve galvanized, can effectively prevent rust.Valve (Famen) is a control component in the fluid delivery system.

Q:What is the diameter of a general pipe valve?: The relation between the common mark and the nominal diameter:1, plastic pipes (U-PVC, water pipes, PPR tubes): Phi 20-DNl5, Phi 25-DN20, Phi 32-DN25, Phi 40-DN32, Phi 50-DN40, Phi 63-DN50, Phi 75-DN65, Phi 90-DN80, Phi 11O-DNl00, Phi 160-DNl1502, seamless pipe: DN15- 22mm DN20- 27mm DN25- phi, Phi Phi Phi Phi 34mm, DN32- 42mm DN40- 48mm DN50- 60mm DN65-, Phi Phi 76 (73) mm, DN80- 89mm DN100- 108mm DN125- phi, Phi Phi 133mm, Phi 159mm, Phi DN150- DN200- 219mm, DN250- 273mm3, DN15---1/2--- four; DN 20---3/4--- six; DN 25---1, DN 32--1 1/4 -- an inch; inch two; DN 40---1 1/2 DN 50--- - an inch and a half; 2 - two inch DN 65---; 2 1/2, two and a half inches; DN 80--- 3 - three inch two; DN 100--- 4 - four inches; DN 125-- 5 - DN 150--- 6 - five inch; six inch 8---- eight inch 200--- DN;

Q:Air compressor out of the gas with what kind of valve control okay, globe valve or other?: Air compressor all copper safety valve (AQ-20) (AQ-25)Air compressor, air release valve and so on. The air compressor rated exhaust pressure is divided into low pressure (0.7~1.0MPa), medium pressure (1.0~10MPa), high pressure (10~100MPa) and ultra high pressure (100MPa or more), to see what kind of installation you are and use

Q:The low pressure in our factory is below 1.6Mpa, medium pressure is 2.5-6.4MPa, high pressure is 10-80MPa.Where's qusetion:1.6-2.5Mpa??? Which section does it belong to?. I think many of them are defined on the Internet But I didn't say, where's 6.4-10Mpa?: According to the GB standard test pressure GB/T13927, "industrial valve pressure test" valve in accordance with the pressure can generally be divided into the following categories:(1) vacuum valve: refers to the working pressure is lower than the standard atmospheric pressure valve.(2): refers to the low pressure valve nominal pressure PN valve is less than 1.6Mpa.(3) medium pressure valve: refers to the nominal pressure of 2.5Mpa, PN, 4.0Mpa, 6.4Mpa valve.(4) high pressure valve: refers to the pressure valve PN 10.0Mpa 80.0Mpa valve.(5) super high pressure valve: nominal pressure PN = 100.0Mpa valve.Normally the stresses are actually pressure (force per unit area). Is generally used to gauge our living environment under 1 standard atmospheric pressure as reference 0 (reference point 0), and the difference between the value of the gauge (pressure gauge usually display is the gauge). But in fact we live in 1 atmospheric environment, coupled with the income of the 1 gauge pressure value is the absolute value of pressure.Standard atmospheric pressure actually has standard engineering atmospheric pressure at (kgf/cm2) and standard physics atmospheric pressure ATM, the former used in the early years, and now generally use the latter. 1atm=1.0332at=1.01325bar (bar) =101.325kPa=0.101325MPa.The valve pressure mainly focus on two parameters: rated working pressure, such as PN16, said the rated working pressure is 16bar (1.6MPa); the maximum permissible pressure difference (this value, the greater the actuator thrust torque required with the larger).

Q:How to better maintain the valve?: We should keep the valve cleanWe should regularly check and maintain the integrity of the valve the other components. As a fixed hand wheel nut fell off, to be filled and can not manage, otherwise it will grind the valve stem upper garden square, gradually lost with the reliability, and even can not startWe do not rely on the valve support other heavy objects, do not stand in the valveThe stem, especially the threaded part, to regular cleaning, the dust has been soiled should be replaced with a new lubricant, because the dust contains hard debris, easy to wear thread and stem surface, affect the service life

Q:Automatic exhaust valve installed in the pipe before and after the installation of other valves need to press it?: In general, the exhaust valve (large diameter) and a maintenance valve, normally open,
