Its main feature is manual operation. The valve stem is manually rotated by the handwheel, and the stem drives the ball to…
1.What is valve nominal pressure? Valve nominal pressure refers to the pressure level specified by the valve size and design standards. It is one of the important size parameters of the valve and is usually marked as PN. Rated operating pressure refers to the pressure range of the valve during normal operation and is also…
What is a check valve? A check valve, also known as a non-return valve or one-way valve, is an important type of valve in fluid systems. The following is a detailed introduction: 1.Structure In terms of structure, the check valve can be devided into three types: lift check valve, swing check valve and butterfly check…
What is a globe valve? A globe valve is a type of valve used in various fluid control systems. Here is a detailed introduction: 1.Structure 2.Working Principle 3.Advantages and disadvantages Globe valves have the following advantages: The disadvantages of globe valves are as follows: The applications of globe valves. There are mainly the following fields:
Valves are used differently in many environments, so there are many different types of valves produced in the market. Stainless steel ball valves, as one of the types, have achieved the representative of high quality valves by virtue of four advantages. What are the five advantages? 1.Strong wear resistance The primary advantage of stainless steel…

What is a gate valve? A gate valve is a crucial type of valve in the fluid control field. Here is an introduction to it: 1.Structure Valve body: It is the main part of the gate valve, which is used to connect pipes and accommodate other components. Usually, it is made of materials like cast…
If you have learnt the introductions of ball valves and butterfly valves earlier in our blog, you will have a basic knowledge about them. Now we can take a look at the differences between these two types of valves. The differences between ball valves and butterfly valves can be distinguished from the following aspects: 1.Different…
What is a butterfly valve? A butterfly valve is a type of valve widely used in fluid control systems. Here is a detailed introduction: 1.Structure Disc: The disc is the core component of the butterfly valve, which is usually a circular plate. It is located in the center of the pipe and rotates around the…
What is a ball valve? A ball valve is a type of ball shutoff valve that is widely used in various industries for fluid control. Here is a detailed introduction: 1.Diagram of a ball valve 2.Working principle 3.Advantages and disadvantages Positive features: Negative features: What are the applications of ball valves. There are mainly the…
Trunnion Mounted Ball Valve is suitable for cutting off or connecting the medium in the pipeline. Using different materials, the forged steel Trunnion Mounted Ball Valve of Topwells can be applied to water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea, and other media. Trunnion Mounted Ball Valve is driven by manual, worm gear…
The relationship between regenerative turbine pumps and valves is mainly reflected in their interdependence and coordination in industrial applications. The regenerative turbine pump is a high efficiency vacuum pump that accelerates gas molecules out of the vacuum chamber through a high speed rotating turbine to achieve a high vacuum effect. This pump is usually…
Ball valve and gate valve are two of the most commonly used valves for controlling the flow of fluid in plumbing or gas systems. These valves have similarities in application, but have different strengths to offer. This guide reviews the key differences between ball valves vs. gate valves, giving you the reference to choose the…
Among the usual structural designs of single-gate, double-gate, wedge, parallel and so on, the wedge double-gate and the wedge elastic gate are the most widely used ones. The former’s gate automatically coincides with the two sides of the seat, while the latter relies on the elastic groove in the middle of the gate wedge to…
Gate valve，for its low fluid resistance, a minor pressure differential, the flow direction maintenance ability, erosion endured sealing surface and flow noninterference, can be applied with a wide range of pressure and temperature. As a common block valve, it is widely used in the oil media of petroleum, chemical, fossil-fuel power plants and in the…
How does a ball valve work? A ball valve is a shut-off device that regulates the flow of a liquid or gas using a rotating ball with a hole. By turning the ball a quarter turn (90 degrees) around its axis, the valve either opens or closes, allowing the medium to pass through or blocking…
The double cut-off slab gate valve with diversion hole is mainly used to cut off the medium.
