Structural features of ball check valve
The ball check valve is also called the ball sewage check valve. The valve body is made of nodular cast iron. The paint surface of the valve body is made of non-toxic epoxy paint after high temperature baking. The paint surface is flat, smooth and bright in color. The rubber-covered metal rolling...Read more -
H71W stainless steel wafer lift check valve working principle and characteristics
Stainless steel wafer lift check valve H71W/stainless steel one-way valve/wafer lift non-return valve adopts short structure size and single disc design. Compared with traditional swing check valve, this series of valves has no external Leakage, can be installed in any position, good sealing perf...Read more -
Diaphragm Valve
Diaphragm valve is a shut-off valve that uses a diaphragm as an opening and closing part to close the flow channel, cut off the fluid, and separate the inner cavity of the valve body from the inner cavity of the valve cover. The diaphragm is usually made of rubber, plastic and other elastic, corr...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 -
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 -
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 -
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 -
The difference between rising stem gate valve and non-rising stem gate valve
The difference on the stem The rising stem gate valve is a lift type, while the non-rising stem gate valve is not a lift type. The difference in transmission mode Rising stem gate valve is a handwheel that drives the nut to rotate in place, and the valve stem is linearly raised and lowered to com...Read more -
What does the valve arrow on the body mean?
The arrow marked on the valve body indicates the recommended bearing direction of the valve, not the flow direction of the medium in the pipeline. The valve with bi-directional sealing function can not be marked with the indicating arrow, but also marked with the arrow, because the valve arrow re...Read more
