What is wafer type check valve?
Butterfly check valve is also called wafer type check valve or double plate check valve, it is a simple structure, convenient installation of check valve, also known as quick installation check valve. It is composed of valve bodies and spring valve cores. It is usually made of stainless steel, ductile iron, and other materials. The two ends of the valve are equipped with sealing rings and clamps.
Wafer type butterfly check valve is a kind of energy saving product, it is based on foreign advanced technologies and is produced in accordance with relevant international standards. This product has excellent interception performance, high safety and reliability, and small flow resistance. It is mainly used in some small diameter, low-pressure pipeline systems, such as petrochemical food processing, medicine, textile, paper, water supply, drainage, metallurgy, energy, light industry, and other industries of the system. It is used as a one-way check valve.
Advantages of cast iron butterfly check valve:
1. Design compact
Due to the gasket is used as the sealing element, there is no need to increase the coordination surface, making the whole valve structure more simple and compact.
2. Easy to install and maintain
The installation and disassembly are convenient and fast. Just the two ends of the valve are stuck on both sides of the outer side of the pipeline to complete the installation. There is no need to disassemble and weld the pipeline, which is very convenient for on-site maintenance and replacement.
3. Use flexibly
The valve is automatically opened and closed, without human intervention, convenient and fast to use.
4. Strong resistance to backflow
When the medium flow direction is opposite to the requirements of the valve, the valve is automatically closed to avoid the occurrence of backflow phenomenon.
5. Low fluid resistance
When the medium flows normally, the wafer type check valve automatically opens, which will not cause resistance to the flow and pressure of the fluid.
6. Wide range of application
The wafer type check valve is widely used in a variety of liquid, gas and steam pipeline systems, suitable for a variety of different industrial environments.
