How to choose the material of WCB/LCB/LCC/WC6/WC for the valve?
W means write, cast; C-CARBON STEEL carbon steel, A, b, and C indicate the strength value of the steel type from low to high. WCA, WCB, WCC represents carbon steel, which has good welding performance and mechanical strength. ABC represents strength level, commonly used WCB. The pipe material corr...Read more -
Causes and solutions to water hammer
1/Concept Water hammer is also called water hammer. During the transportation of water (or other liquids), due to sudden opening or closing of Api Butterfly Valve, gate valves, check vavles and ball valves. sudden stops of water pumps, sudden opening and closing of guide vanes, etc., the flow ra...Read more -
How to convert Valve Pressure PSI, BAR and MPA?

Flow characteristics of regulating valve
The flow characteristics of the control valve mainly include four flow characteristics: straight line, equal percentage, quick opening and parabola. When installed in the actual control process, the differential pressure of the valve will change with the change of the flow rate. That is, when the...Read more -
How regulating valves, globe valves, gate valves and check valves work
Regulating valve , also called control valve, is used to control the size of fluid. When the regulating part of the valve receives a regulating signal, the valve stem will automatically control the opening and closing of the valve according to the signal, thereby regulating the fluid flow rate an...Read more -
What is the difference between gate valve and butterfly valve?
Gate valves and butterfly valves are two very commonly used valves. They are very different in terms of their own structures, usage methods, and adaptability to working conditions. This article will help users better understand the differences between gate valves and butterfly valves. Better help...Read more -
The main difference between pressure reducing valve and safety valve
1. The pressure reducing valve is a valve that reduces the inlet pressure to a certain required outlet pressure through adjustment, and relies on the energy of the medium itself to automatically maintain a stable outlet pressure. From the point of view of fluid mechanics, the pressure reducing va...Read more -
Summary of the differences between globe valves, ball valves and gate valves
Suppose there is a water supply pipe with a cover. Water is injected from the bottom of the pipe and discharged toward the pipe mouth. The cover of the water outlet pipe is equivalent to the closing member of the stop valve. If you lift the pipe cover upward with your hand, the water will be disc...Read more -
What is the CV value of a valve?
CV value is the English word Circulation Volume The abbreviation of flow volume and flow coefficient originated from the definition of valve flow coefficient in the field of fluid engineering control in the West. The flow coefficient represents the flow capacity of the element to the medium, spec...Read more
