1. Manual Wafer Ball Valve Description：
A ball 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 butterfly valve, which allows for quick shut off. Ball 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 Ball Valve
a)Cast hole. Flange connection meet ANSI 125/150# DIN PN10/16 BS4504 PN10/16 in the meanwhile.
b)Soft seat. Replaceable. Increase of service life.
c)Double half shaft without pin.
d) Square and short neck. Easy to stick scutcheon and cost saving.

5.FAQ
1. What is manual wafer ball valve?
A: Wafer style is the more common of the two and is less expensive than the lug style. The wafer style ball valve is just about the standard. It ís so common that no one even bothers to use the word "wafer" when ordering a ball valve. It is taken for granted that if a ball valve is ordered, a wafer style will be received.
2. How about the Installation of the Wafer Style Ball 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 ball valve?
A: A ball 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 "ball" 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: the rest are hot, the living room outside all the heating pipe valve closed, the living room heating is still not hot, after the water for a while hot, and cold
- It is loaded against the supply and return water pipe is not underground do in next time if it is to see if there is any water on the side of the baffle remember from the baffle recently if it is normal that is motivated next must put off the baffle
- Q: Standard and specification for pressure test of valves
- (11) when the valve with drive device is tested and its tightness is tested, the sealing test shall be carried out by using the driving device to close the valve. For manual drive units, seal test shall also be done with the actuating closing valve.(12) the by-pass valve installed on the main valve after the strength test and the sealing test. The strength and tightness test of the main valve is carried out. The main valve should be opened when the closing member is opened.(13) iron valve strength test, the application of Pratia tapping valve and valve cover, check whether there is any leakage.(14) the valve test, in addition to the provisions of the plug valve to allow sealing surface oiling, other valves are not allowed in the sealing surface of the oil test.(15) when the valve pressure test, the blind plate on the valve pressure should not be too large, so as to avoid deformation of the valve, affecting the test results (cast iron valve if pressed too tight, will be damaged).(16) after the valve test pressure, should promptly remove the water and clean the valve, should also be prepared for the test record.
- Q: What are the valves at home?
- Valve used in the family is commonly used, the following are several:On the water pipe are: total table of the ball valve (32mm), in charge of the (25mm), as well as for the toilet, washbasin, water heater angle valve (20mm).Other commonly used gas pipelines, valves, pressure reducing valves and the like.

- Q: I used to do pumps, and now feel the future of the valve better, looking for a valve to do proxy, but my own economic strength is not good, I do not know if there is no possible to do?
- As the two floor said, looking for agents depends on your targeted customer base is better sign is the price of comparative advantage of the brand. Now the valve on the market in Fujian, Wenzhou. Especially, these valves are faced with the market price, the quality of course needless to say. Maybe these valves would sell large the early recovery of funds, is also rich. But for a long time, the problem appeared, quality problems will make you sleepy fishing, I suggest you. You can't do anything sales quality and good reputation of the valve.In the few I know better. Now the best reputation is Guanlong, but the price comparative advantage or spring.
