In a fire protection system, a jockey pump foot valve plays a crucial yet often under-the-radar role. To understand its significance, we need to first look at the context of the jockey pump itself. A jockey pump is an essential component within a fire protection system. Its primary function is to maintain the required pressure…
In a pipeline system, valves are basic control components. Their main functions are to isolate equipment and the pipeline system, regulate the flow rate, prevent backflow, and regulate and discharge pressure. They can be used to control the flow of various types of fluids, such as air, water, steam, various corrosive media, slurries, oils, liquid…
Gate valves shall be of the OS&Y or IS&Y type. OS&Y stands for Outside Screw and Yoke. When the handwheel of the OS&Y gate valve is rotated to open the valve, the valve stem will rise.Here are some examples of OS&Y gate valve specification parameters: ASME B16.10, API 602, ASTM A182-F304, TRIM.15-HF, CL150, BB and…
What is a pressure reducing valve? Do I really need a pressure reducing valve? Pressure reducing valve, its abbreviation is PRV. The pressure reducing valve, also known as a regulator valve, is a device widely used in the industrial field to regulate the pressure of fluids. It is mainly used to reduce the high pressure…
In industrial product procurement, both swing check valves and wafer check valves play important roles, but there are significant differences between them. The main differences between swing check valves and wafer check valves are as follows: Structure. Swing check valves: They have a hinged disc that swings open to allow forward flow and closes under…
In the world of industrial valves, the floating ball valve and the trunnion ball valve stand out as two widely-used types. These valves are essential for regulating fluid flow in industries such as oil and gas, chemical processing, and water treatment. Understanding their differences in detail is import for one to make the best decisions…
A inch and a half ball valve, that is a 1-1/2” ball valve refers to a ball valve with a pipeline diameter of 1and 1/2 inches, which is commonly used in household water pipes and air conditioners systems. I. The size of the 1-1/2” ball valve The 1-1/2” ball valve, actually means that the pipeline…
As two essential types of valve in industrial and civil pipeline systems, globe valves and gate valves both play a crucial role in controlling the flow of fluids. However, they have their own characteristics in regards of structure, operating principle, and applicable scenarios. Analysis of the similarities and differences between the two will provide us…
The slient check valve belongs to the category of automatic valves. Its function is to prevent the medium in the pipeline from flowing backwards. It is mainly used on pipelines where the medium flows on one way, allowing the medium to flow in only one direction to prevent accidents. The maintenance of slient check valves…
A check valve, also known as a non return valve or one way valve, is a valve allows the fluid to flow in only one direction, while automatically closing to prevent the backflow of the fluid in the opposite direction. The types of check valves are various and complex. Commonly used check valves according to…
For valves working in corrosive media conditions, corrosion prevention is the most crucial job. If the metal materials of chemical valves is not correctly selected, very esily it may damage the equipment at best, and at worst, it may lead to accidents or even disasters. According to some relevant statistics, about 60% of the chemical…
The check valve is used when the medium is required to flows only in one direction. It can prevent backflow. In terms of structure, the check valve can be classified into three types: lift check valve, swing check valve and butterfly check valve. Topwells here will introduce the differences between the lift check valve and…
A three way ball valve is a valve used to control the flow of media between three pipelines. Its working principle and structural characteristics have led to its wide application in many industrial fields. The following is a detailed introduction to three way ball valves: I. What is a three way valve and its types?…

A non slam check valve is a special type of check valve that can prevent the slam or water hammer when the valve closes. Because the non slam check valve is equipped with a special pressure reducing device. Before the valve closes, it can quickly reduce the liquid pressure inside the pipeline to below the…
What is Industrial Flange Gate Valves? An industrial flange gate valve is a type of valve used to control the flow of fluids in industrial pipeline systems.
