Main classification and service conditions of valve sealing materials
Valve sealing is an important part of the whole valve, its main purpose is to prevent leakage, the valve sealing seat is also called sealing ring, it is an organization that is directly in contact with the medium in the pipeline and prevents the medium from flowing. When the valve is in use, ther...Read more -
What should we do if the butterfly valve leaks? Check out these 5 aspects!
In the daily use of butterfly valves, various failures are often encountered. The leakage of the valve body and bonnet of the butterfly valve is one of the many failures. What is the reason for this phenomenon? Are there any other glitches to be aware of? The TWS Valve summarizes the following si...Read more -
Installation environment and maintenance precautions of butterfly valve
TWS Valve Reminder Butterfly valve installation environment Installation environment: Butterfly valves can be used indoors or outdoors, but in corrosive media and places that are prone to rust, the corresponding material combination should be used. For special working conditions, please consult Z...Read more -
Precautions for installing and using butterfly valves
Butterfly valves are mainly used for the adjustment and switch control of various types of pipelines. They can cut off and throttle in pipelines. In addition, butterfly valves have the advantages of no mechanical wear and zero leakage. However, butterfly valves need to know some precautions for i...Read more -
What are the commonly used sealing materials for valves?
There are many types of valves, but the basic function is the same, that is, to connect or cut off the medium flow. Therefore, the sealing problem of the valve is very prominent. To ensure that the valve can cut off the medium flow well without leakage, it is necessary to ensure that the v...Read more -
What are the options for butterfly valve surface coating? What are the characteristics of each?
Corrosion is one of the important elements that cause butterfly valve damage. In butterfly valve protection, butterfly valve corrosion protection is an important issue to consider. For metal butterfly valves, surface coating treatment is the best cost-effective protection method. The role ...Read more -
The working principle and maintenance and debugging method of pneumatic butterfly valve
The pneumatic butterfly valve is composed of a pneumatic actuator and a butterfly valve. The pneumatic butterfly valve uses a circular butterfly plate that rotates with the valve stem for opening and closing, so as to realize the activation action. The pneumatic valve is mainly used as a shut-off...Read more -
Butterfly valve installation precautions
1. Clean the sealing surface of the butterfly valve and the dirt in the pipeline. 2. The inner port of the flange on the pipeline must be aligned and press the rubber sealing ring of the butterfly valve without using a sealing gasket. Note: If the inner port of the flange deviates from the rubber...Read more -
How to prolong the service life of fluorine-lined butterfly valve
Fluoroplastic lined corrosion-resistant butterfly valve is to place polytetrafluoroethylene resin (or profile processed) on the inner wall of steel or iron butterfly valve pressure-bearing parts or the outer surface of butterfly valve inner parts by molding (or inlay) method. The unique propertie...Read more -
How does the air release valve work?
Air release valves are used in pipeline air of independent heating systems, central heating systems, heating boilers, central air release conditioning, floor heating and solar heating systems. Working principle: When there is gas overflow in the system, the gas will climb up the pipeline a...Read more -
Differences and commonalities between gate valves, ball valves, and butterfly valves
The difference between gate valve, ball valve and butterfly valve: 1. Gate valve There is a flat plate in the valve body which is perpendicular to the flow direction of the medium, and the flat plate is lifted and lowered to realize opening and closing. Features: good airtightness, small fluid re...Read more -
What is the difference between handle lever butterfly valve and worm gear butterfly valve? How should choose?
Both the handle lever butterfly valve and the worm gear butterfly valve are valves that need to be operated manually, commonly known as manual butterfly valves, but they are still different in use. 1. The handle lever rod of the handle lever butterfly valve directly drives the valve plate, and th...Read more
