7 Types of Wear Produced During Valve Operation
Due to frequent opening and closing and erosion of the fluid medium, the wear of sanitary valves is generally classified into the following types. Adhesive wear Adhesive wear is usually caused by sliding between metals. As the two pieces of metal are pressed together, the uneven surfaces come into contact with each other to form contact […]
Read moreThe Maintenance of Valve Stuffing
1. Stuffing is a key sealing member that is directly related to whether there’s a leakage when the valve opens or closes. If the stuffing is no longer functional and causes leakage, the valve is in effect no longer functional. Especially the urea pipeline valve, because of its relatively high temperature and corrosion, stuffing is […]
Read moreThe Mechanism and Structure of Solenoid Valve
What are the types of solenoid valves? Tracing the history of the development of the solenoid valve, so far, it can be divided into three categories according to its mechanism. These are direct-acting type, distributed direct-acting type, and pilot type. And according to the differences in the structure of the valve flap, materials, and mechanism, they […]
Read moreWhat are the Effects of the Coating on the Valve Surface?
Generally speaking, cast iron and carbon steel valves are usually painted with different types and thicknesses of paint for good protection. Sanitary valves are generally used for the transportation of water, oil, steam, etc., and are in direct contact with the metal surface, thus prone to serious corrosion under the action of oxygen. Coatings are generally […]
