Due to the functions of sealing elements on the valve channel, such as cutting and connecting, adjusting and distributing, separating and mixing media, the sealing surface is often corroded, eroded, and worn by the media, making it highly susceptible to damage. There are two reasons for damage to the sealing surface: artificial damage and natural damage. Human damage is caused by factors such as p...

Check valves may be the most misunderstood valve in history. If you mention check valves to most factory personnel, the typical reaction is' they don't work '. In fact, these personnel are likely to have removed internal components or refurbished the system to avoid the use of check valves. In other words, these valves may be the least popular valves currently in use. This article will explore the...

1.To prevent reverse flow of the medium, check valves should be installed on equipment, devices, and pipelines; 2. Check valves are generally suitable for cleaning media and should not be used in media containing solid particles and high viscosity; 3. Generally, vertical lift check valves should be used on horizontal pipelines with a nominal diameter of 50mm; 4. The straight lift check valve can b...

First of all, we need to know what mesh size means: it refers to the particle size or thickness of the material, which is generally defined as within 1 inch × 1 inch (25.4mm × The number of mesh holes in an area of 25.4mm is defined as the number of mesh holes in the sieve, and the number of mesh holes that the material can pass through is defined as the number of mesh holes. This type of filter i...

Bellows globe valves, also known as bellows sealed globe valves, form a metal barrier between the fluid medium and the atmosphere through automatic roll welding, ensuring a zero leakage design of the valve stem. The interior of the bellows stop valve adopts a bellows structure, and the lower end of the stainless steel bellows is welded to the valve stem to prevent process fluid from corroding the ...

Steam trap refers to a water trap, a water trap, a water trap, or a steam trap. Its basic function is to quickly discharge condensate, air, and carbon dioxide gas from the steam system; Simultaneously, it automatically prevents steam leakage to the maximum extent possible. There are many types of steam traps, which can be classified into mechanical, float ball, open up float, open down float, and ...

What is the difference between forged valves and cast valves? Why should it be divided into two types of lectures? Next, this article will explain how to distinguish between forged valves and cast valves. Forged valves Forged valves are forged and usually used on high-grade pipelines, with a relatively small diameter, usually below DN50. 1. Forging: It is a processing method that uses forging mach...
