1. Selection of gate valve In general, gate valves should be preferred. Gate valves are not only suitable for steam, oil and other media, but also for medium containing granular solids and large viscosity, and suitable for vent and low vacuum system valves. For media...Read more -
Wide range of uses of butterfly valves
Butterfly valve is a kind of valve, which is installed on the pipeline to control the flow of medium in the pipeline. The butterfly valve is characterized by simple structure and light weight. Its components include transmission device, valve body, valve plate, valve ste...Read more -
The characteristics and working principle of butterfly check valve
Butterfly check valve is also called butterfly check valve. HH77X butterfly check valve is an automatic valve that works according to the flow state of the medium in the pipeline. It can effectively prevent the pipeline medium from flowing back and prevent the pumps and ...Read more -
What is the difference between butterfly valve handle drive and worm gear drive? How should I choose?
Both the handle butterfly valve and the worm gear butterfly valve are valves that require manual operation. They are commonly referred to as manual butterfly valves, but there are still differences in the use of the two. 1. Handle butterfly valve The handle rod directly drives the valve plate...Read more -
About the use of check valves
Usage of check valve 1. Swing check valve: The disc of the swing check valve is disc-shaped, and it rotates around the shaft of the valve seat passage. Because the inner passage of the valve is streamlined, the flow resistance ratio increases. The drop check valve is small, suitable for low flo...Read more -
Classification of valves
In fluid piping system, valve is the control element, its main function is to isolate equipment and piping system, regulate flow, prevent backflow, regulate and discharge pressure. Valves can be used to control the flow of air, water, steam, various corrosive media, mud, oil, liquid metal and rad...Read more -
What is the CV value of the foot valve?
CV value is Circulation Volume Flow volume shorthand, flow coefficient abbreviation, originated in the western fluid engineering control field for the valve flow coefficient definition. The flow coefficient represents the ability of the element to flow medium, specifically in the case of a foot v...Read more -
What conditions need to be met when stainless steel valves are sealed
Valves are used as a complete set of air separation equipment in chemical systems, and most of their sealing surfaces are made of stainless steel. In the grinding process, due to improper selection of grinding materials and incorrect grinding methods, not only the production efficiency of the val...Read more -
Precautions for installation and use of butterfly valves
Butterfly valves are mainly used for the adjustment and switch control of various types of pipelines. They can cut off and throttle in the pipeline. In addition, butterfly valves have the advantages of no mechanical wear and zero leakage. But butterfly valves need to understand some precautions f...Read more -

Regulations and requirements for pipeline valve installation
1. When installing, pay attention to the direction of medium flow should be consistent with the direction of the arrow voted by the valve body. 2. Install a check valve before the condensate after the trap enters the recovery main pipe to prevent the condensate from returning. 3. Rising stem valv...Read more -
Selection principles and applicable occasions of butterfly valves
1.Where the butterfly valve is applicable Butterfly valves are suitable for flow regulation. Since the pressure loss of the butterfly valve in the pipeline is relatively large, it is about three times that of the gate valve. Therefore, when selecting the butterfly valve, the influence of the pres...Read more
