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: Remove the handle and lever the stem rotation with a wrench,
First you know what valve you need, or you know where to use the pipe material, so you do not need to understand the valve material.
Q: What is the difference between valve j941H-40 and j41H-40?
The difference is that one drive is electric, one is transmission, and the other is manual."Valve design manual" showsJ- stop valve9- electric4- connection means flange connection1- through typeH- sealing surface is alloy40- operating pressure is 4.0Mpa (or 40 kg)More than one, 9, 9 fingers, electric, more than an electric.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. The valve according to the material is divided into cast iron valves, cast steel valves, stainless steel valves (201, 304, 316), chrome molybdenum steel, chromium molybdenum vanadium steel valves, valve, dual phase steel valves, plastic valves, non-standard customized valve material etc..
Q: the valve to an electrical signal, with this signal to control other components, ask: what valve?
Online search "air switch", many suppliers.You may choose your pipe according to your pipe diameter.The flow meter can also be used to control the flow of operation
Q: What kind of valve is it? How do you see the status of the switch?
Globe valve, not ball valveClockwise (Bell) needle to reduce the flow to the end of the shutdown, the counter clockwise to open. You can turn the multi circle plate will also lift up and down. The spindle, to the top is open, down to the edge off.The ball valve has a strip handle, the line is connected, and the cross is turned off
Q: What does the RF of the valve mean?
Convex flange, RAISED, FACE,At 150#, 300#, height is 2MMAbove is 7MM,
Q: In the decoration, I do not know where to get the valve, what kind of products should be bought?It is hard to fit the valve in the water inlet of the house. If not, can you? Will it have any effect on future use?
Common valve position is few, 1 or 2 wash basin faucet pipe toilet pool 3 4 water heater 5 water washing machineThese positions require only simple ball valves or globe valves. Gas valves need not be considered, provided by gas installation companies (specific standards).The main valve can achieve the above water source control, the installation of the branch valve is to take into account the maintenance is convenient, does not affect other water.
Q: What are the technical requirements of valves, such as "Z15W-25T"?
The first Z represents the gate valve;The second bit is omitted, indicating the handle or handwheel;Third bit 1, indicating internal thread connection;Fourth bit 5, indicating dark wedge rigid single gate;Fifth W, which means the sealing materials are the main body material of the valve;The second paragraphThe first 25, said the nominal pressure is 2.5MPa (valve used in accordance with the pressure level of GB/ 1048, the use of GB/T 1048 standard 10 times the unit of MPa (MPa) value, otherwise the unit value is MPa. If it is a power station valve, the unit value is MPa.)Second bit T indicating copper and copper alloy for the valve body.
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: What is the diameter of a general pipe valve?
In fact, the essence of the problem is the corresponding relationship between the nominal diameter and other dimensioning methods. Valves are generally marked with nominal diameter (DN***), such as DN150, DN100 and so on. There are many kinds of marking methods for pipes, such as outer diameter, inch inch, nominal diameter, etc.. Only when the other dimensioning is converted to nominal diameter, the valve and the pipe correspond to each other.
Q: Is there any difference between the valve and the water valve?
It doesn't make any difference. The valve can pass through the water or the oil
