Product Description:

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's the advantage of using three way valves?
The principle of three way valve:The most obvious three valves and other valves is the difference in appearance, three way valve has three channels, mainly used to change the medium to flow through valve three, which in addition to import A, B, C and reversing port of export, common valve is not capable of changing the flow direction of medium function. The flow direction of the medium can be determined according to requirements.
Q:Why use the pump outlet valve to adjust the flow rate?
This is the most widely used method of regulating flow, while protecting pumps and motors. The general classical installation method is as follows: the pump outlet is equipped with a vibration reduction joint, and then a gate valve control switch, and then install a multi-function water pump valve to adjust the flow.
Q:What is the flow medium of the valve?
What is the valve. If the water through the valve, the medium is water. I hope I can help you.
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.
Q:What is the normal temperature on the valve?
At normal temperatures are below 120 degrees. A lot of valve sealing surface can only reach 120 degrees
Q:What is the valve before and after the pump?
General pump should be installed before and after the pressure regulating valve, pump installed before the pressure drop valve, pump installed after the pressure regulator valve!
Q:What is the term "Z41H-16C" on the line?
The ram of the Z41H-16C is linear with the stem, called (also known as the bar gate valve). Usually there is a trapezoidal thread on the lifter. The rotating motion is changed into a straight line through the nut at the top of the valve and the guide groove on the valve body. That is to say, the operating torque is changed into the operating thrust.
Q:How to better maintain the valve?
Use and maintenanceThe maintenance of the aim is to extend valve life and ensure reliable opening and closingThe stem threads, often with the stem nut friction, to a little yellow dry coating oil, molybdenum disulfide or graphite, lubricationWe do not often open and close the valve, but also on a regular basis handwheel on the stem threads to add lubricant to prevent bitingThe outdoor valve, to increase the protection sleeve on the stem, to rain, snow, dust and rustIf the mechanical valve system to be fixed, to add time to the gearbox oil
Q:Mechanical valve
I think it's the filter. The valve unit you know, you know, or Baidu. Then contact.
Q:Where is the Hefei valve market?
At the intersection of Mingguang Road and Shengli Road, the southwest side is all made of valves
