Hard sealed ball valves are much more stringent in operating conditions than soft sealed ball valves. High temperature, strong corrosion, and media such as dust, particles, and mud pose significant obstacles to the continuous use of hard sealed ball valves. During the use of hard sealed ball valves, valve failures often occur due to operating conditions or human factors, forcing maintenance. Under...

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...

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...

1. The filter screen of the Y-type filter is generally made of stainless steel; 2. The general definition of filter mesh size refers to the number of mesh holes within an area of 1 inch * 1 inch (25.4mm), that is, the number of mesh holes in the screen; 3. The number of mesh used for general waterways is 8-30 mesh; 4. The filter mesh size of the chiller host is generally 16-20 mesh. Corresponding ...
