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 use of each brand in the super high-rise, commercial complex, hotel? Price comparison of each brand? In the general valve, balance valve, electric valve, who did the best? Any knowledge about the valve, please ~ ~ thank you for your generous with your criticism
- Johnson, SIEMENS, Honeywell is mainly in the electric valve inside, because they themselves do automatic control system, so the electric valve matching is strong, but also manufacturers own production, other types of valves they several brands are generally looking for OEM agents do, is not recommended.
- Q: Where is the filling portion of the valve?
- The valve stem and the body of the valve at the junction of the pressure cap, the pressure cap is filled inside.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.
- Q: Which industries need valves?
- 3., the other side of energy development is energy conservation, so from the perspective of energy conservation, it is necessary to develop steam traps, and to sub critical and supercritical high parameter development;4., the construction of power stations to large-scale development, so the use of large diameter and high pressure safety valve and relief valve, but also need to quickly open and close the valve;5., for the needs of complete sets of projects, the supply of valves from a single species to more varieties and specifications. The valve required for an engineering project is growing with the full availability of a valve manufacturer.In the next few years, the overall trend in demand for the valve for the upward trend, the valve of this large volume of industrial supplies, its demand in steady growth. Among them, the demand for a larger number of valves in turn are: ball valve (15.5%), cut-off valve (12.9%), safety valve (12.5%), gate valve (12.5%), butterfly valve (10.6%), regulating valve (8%) and check valve (6.1%).
- 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: Is the filter also valve?
- Filters are generally used in the pipeline, are ancillary products, strictly divided, it does not belong to the valve category
- Q: I'm going to put a solar energy and an electric water heater installed in the same hot water pipe, a valve, a valve open and close the valve B and vice versa the installation of solar and electric water heater, there can be no linkage valve?
- In industry, you say this, such as using two butterfly linkage and composition of the three-way valve to use. But civilian should be few, demand is very little ah. It is estimated that you can only install two valves and then use both hands at the same time to perform linkage.
- Q: What valve does the high pressure by-pass valve DN254 * 800 belong to?
- High pressure bypass valve DN254 * 800 belongs to bypass valve.Function of bypass systemThe turbine by-pass device mainly has three functions of starting and overflowing:1 in the cold, warm and hot, the bypass system can realize the optimal unit start-up and shut-down in turbine operating conditions, start and stop curve can meet the requirements, two types of automatic and manual operation, with the establishment of the boiler steam temperature and steam turbine components. To shorten the start-up time.2. when the turbine is tripped, the bypass system can operate at a high speed and reach full open position.3., when the turbine load changes, the by-pass system has the regulating function, and the safety valve action can be avoided and the operation stability of the boiler can be improved when the instantaneous change of the moving state.The function of the bypass control valve:The main function of steam turbine bypass system is high pressure steam adjusting throttling and superheated steam cooling. The bypass valve to perform these functions at the same time and in low noise, small vibration, valve resistance to achieve its goal of temperature and pressure loss under the condition of touch.
- Q: What do letters represent in the QF-2 and PX-32 valve models?
- Other letters of the valve indicate explanations and regulations! You never ask again when you ask again!
- Q: Valve pressure grade division
- Valves are classified by pressure:Vacuum valve - valve with operating pressure below standard atmospheric pressure.Low pressure valve - nominal pressure PN is less than 1.6MPa valve.Medium pressure valve - nominal pressure PN 2.5~6.4MPa valve.High pressure valve - nominal pressure PN10.0~80.0MPa valve.Ultra high pressure valve - nominal pressure PN greater than 100MPa valve.
- Q: What is the difference between a stop valve (a power station valve) and other valves?
- High pressure, special material, complex structure, seldom manual operation.
