Monel alloys, cast nickel alloys, Hastelloy, etc. are all materials used to manufacture special purpose valves. Nickel Alloy: Also known as Monel alloy, it is an alloy made of metal nickel as a matrix by adding copper, iron, manganese and other elements. Monel is a high nickel-copper alloy with good corrosion resistance. Monel alloy is a Ni-Cu alloy in nickel-based corrosion-resistant alloys. …

The safety valve is a special valve that is in a normally closed state under the action of external force. When the pressure of the medium in the equipment or pipeline rises beyond the specified value, it discharges the medium to the outside of the system to prevent the medium pressure in the pipeline or equipment from exceeding the specified value. . Safety valves are automatic valves, mainly use…

The sealing surface leaks 1. There are sundries in the butterfly plate and sealing surface 2. The closing position of the butterfly plate and the sealing surface is not properly matched…

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…
