We know that the use of the four-way ball valve is still in place for many pipeline controls, but we also need to be prepared to prevent leakage during use. We should also be familiar with the common methods, so everyone knows that the four-way ball valve prevents leakage. …

There are different types of eccentric sealing butterfly valves, and the fields of application and their characteristics are naturally different. But fundamentally, the basic principle of eccentric sealing butterfly valve has the same purpose. Our company produces eccentric sealing butterfly valves of various materials. There are single eccentric sealing butterfly valve, double eccentric sealing b…

The valve or pipeline flange cover cannot be disassembled. If it is not prepared to connect with the pipeline, the temperature difference and foreign matter will cause the surface of the PTFE flange to be bumped, scratched, deformed or affect the performance of the insulation valve.…

The electric angle control valve usually adopts the flow direction of the open type (that is, the bottom enters and the side exits), and the electric actuator contains the feeding function, which accepts a unified 4-20mA or 1-5V·DC standard signal, and converts the current signal into phase. The corresponding linear displacement automatically controls the opening of the regulating valve to achieve…

As we all know, the corrosion damage of metal has a considerable impact on the service life and reliability of the valve. The influence of mechanical and corrosive factors on metals greatly increases the total wear of the contact surfaces. The total amount of wear on the friction surfaces of the valve during operation. During valve operation, friction surfaces can wear and be damaged due to simult…

What are the three types of swing check valves? A valve that opens and closes with the force of the medium flow to prevent the backflow of the medium is called a check valve. Check valves belong to the category of automatic valves. Mainly used in pipelines where the medium flows in one direction, allowing the medium to flow in only one direction to prevent accidents.…

This type of globe valve is designed in strict accordance with the ASMEB16.34 standard; the connection between the valve body and the bonnet, the installation of the stuffing box, the valve stem nut, and the upper seal are all designed in strict accordance with API600. The valve material selection fully complies with API600 requirements. The structural length conforms to ASMEB16.10; the flange con…

The silent check valve belongs to the automatic valve category. Its function is to prevent the backflow of the medium in the pipeline. It is mainly used in the pipeline where the medium flows in one direction, and only allows the medium to flow in one direction to prevent accidents.…
