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 -
Valve as a tool has been born for thousands of years
The valve is a tool used in the transmission and control of gas and liquid with at least a thousand years of history. At present, in the fluid pipeline system, the regulating valve is the control element, and its main function is to isolate the equipment and the pipeline system, regulate the flow...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 -
Difference between soft seal butterfly valve and hard seal butterfly valve
Hard seal butterfly valve Hard sealing of butterfly valve refers to that both sides of the sealing pair are made of metal materials or other hard materials. The sealing performance of this kind of seal is poor, but it has high temperature resistance, wear resistance and good mechanical performanc...Read more -
Applicable occasions for butterfly valve
Butterfly valves are suitable for pipelines that transport various corrosive and non-corrosive fluid media in engineering systems such as coal gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, chemical smelting, power generation and environmental protection, and are used to a...Read more -
Introduction to the application, main material and structural characteristics of the wafer dual plate check valve
Wafer dual plate check valve refers to the valve that automatically opens and closes the valve flap by relying on the flow of the medium itself to prevent the backflow of the medium, also known as check valve, one-way valve, reverse flow valve and back pressure valve. Wafer dual plate check valve...Read more
