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
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 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: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: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?
- 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.Pressure values are the only indicators that distinguish these valves.
- Q:What does the "Z45T-16" valve mean?
- Z - gate valve4 - flange connection5 - Dark pole, stem non lifting (gate valve structure)T - copper alloy, valve sealing face code16 - pressure code, 1.6MPaMaterial code for grey cast iron valves of nominal pressure less than or equal to PN16 shall be omitted in model preparation.May refer to JB/T 308 valve model compilation method
- Q:What valve is the DN 25?
- That is, the inner diameter of the valve is 25 millimeters
- Q:Where is it installed, what is the role, what is the material, and are there other alternatives instead of this effect?
- Valve packing in the valve under the gland to prevent leakage, you can use ordinary asbestos rope and butter emergency replacement
- Q:What valve should be used to test the water valve?
- 1, ball valve.2, the water test valve can be ball valve, gate valve, stop valve, installed in the fire sprinkler system at each level of the end of the pipe.
- Q:What are the other valves used for the control of dual-use items?
- This is the export licence for dual-use items and technologies.The electronic key issued by Beijing is only qualified for this certificate.We can do that
- Q:What items and detailed procedures should be inspected for valve size inspection?
- The American Standard (American Society of mechanical engineers ASME B 16.10-2000). Internet access can be downloaded, such as free standards to share and download sites. If you need any other valve standard, send me the mailbox.
- Q:Standard and specification for pressure test of valves
- Welcome to Beijing Shan'er pipeline control components Co. Ltd. consulting
- 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,
