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:Which valves are installed in a directional manner?
Depends on the specific valve is one-way seal or two-way seal?
Q:How about leaking water pipe valve?
It depends on where the place is leaking.1, if it is household valveA, the valve and pipe connections at the leakage, in the connection, do not rub tape (the best counter clockwise direction, so that when the valve is connected, the more twisted the more tight) ;B, if the valve itself in the leak, there are ways, it is necessary to open the valve, in which to add sealed or O ring, but it is recommended to replace a more convenient.2, if it is industrial valvesA, industrial valves leaking, if not the valve itself in the leak, then in the valve and pipe connections to join the sealing ring,B, if the valve itself is leaking, it is best to return to the manufacturer for maintenance, if not convenient, then only the manufacturers to come here for maintenance.
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:Is the valve galvanized?
Butterfly valve gate, some hot-dip galvanized, and other valves are not.
Q:How to suppress the valve?
Valve pressure is generally divided into 2 parts. One is shell pressure test, one is sealing test pressureShell pressure test is 1.5 times the pressure of the valve. For example, the pressure on your valve is 16 pressure. Then the shell test pressure will reach 24 pressureThe pressure on the seal is 1.1 times the pressure of the valve. For example, the pressure on your valve is 16 pressure. Then the pressure test on the seal will reach 17.6 pressure. That's all right.
Q:Which industries need valves?
Valve as a general component, widely used in various industries, but there are three main purpose of application in various industries:1, routine inspection needs;2, new projects supporting;3, emergency reserves.Valve market trendsDue to changes in user demand, the market trend of valve products will also change accordingly. In the future, the main trends are as follows:1 with the transfer of oil development to the mainland oil fields and offshore oil fields, and the power industry under the 300 thousand kilowatts of thermal power to more than 300 thousand kilowatts of thermal power and hydropower and nuclear power development, and valves should be changed based on device applications and the corresponding changes in its performance and parameters;2 urban systems generally use a large number of low-pressure valve, and to the development of environmentally friendly and energy-saving, low iron gate that is used in the past gradually shifted the environment-friendly plastic sheet valve, balance valve, metal sealed butterfly valve and the center line butterfly valve seal transition, oil and gas pipeline projects to develop in the direction, which in turn requires a large number of flat gate valve and ball valve the;

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 are the specifications of the valves PN25, DN50?
Upstairs professional level can be seen very solid.... Clap your hands... Popular speaking, that is, the valve bore is 50, resistance to pressure is below 25, is no problem.
Q:What is a lift rod valve?
Lever valve stem nut in the valve plate, it with the disc (hand wheel) to open the turn, its stem pull the valve head and higher than the valve disk, also known as the bar valve. It is different from the dark rod valve, dark rod valve stem nut in the valve body, when the disc rotates, the stem will not rise.
