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.
2.Main Features of the Manual Wafer Butterfly Valve

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 do letters represent in the QF-2 and PX-32 valve models?
- You check it on the national standard! One is accurate!
- Q:How does the valve open?
- The general water switch valve and valve is counterclockwise, but there are some special components are clockwise off, specific can correct the switch travel around open to see, do not be too fierce force damage to the switch, you can switch with a wrench
- Q:Valve connections - two how do different connections work?
- The connection of two different connection forms is achieved by a transition conversion connector

- Q:How about leaking water pipe valve?
- What specific circumstances, I teach you repair what valve, how big, which seal leaks
- Q:High and low pressure valve is how to distinguish?
- Ultra high pressure valve nominal pressure PN = 100MPa; high pressure valve nominal pressure PN10.0MPa ~ 80.0MPa; medium pressure valve, nominal pressure of PN2.5MPa ~ 6.4MPa; low pressure valve, nominal pressure PN is less than or equal to 1.6MPa
- Q:What does the whole copper valve mean?
- Except the handwheel, all the material of the valve body is copper
- Q:How can you replace the other valve when the main valve is not closed and no water is stopped?
- Not recommended against the flood to repair the valve, first you have to be repaired, second may be more complex, it is not easy. I have a bad experience this, take the valve, because it is plastic, and aging, the thread is broken, the new is not on do not have to flow out of the water, get it is. To find the valve, the mess!
- Q:G what's the meaning of the valve?
- Valve with other function or with other special mechanism, fill in a Chinese language before the valve type code number
- 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.
