Introduction of Check Valves via Pictures and Check Valve Diagram

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…

lift check valve

Differences Between Swing Check Valve and Lift Check Valve

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…

high pressure flange gate valve

The Main Application Scenarios and Materials of Industrial Flange Gate Valves

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. It opens or closes the passage by the vertical movement of the gates. When the gate is fully raised, the fluid can pass through the valve unobstructed; when…

Why is a Trunnion Ball Valve More Suitable for a Sludge Discharge Pipeline?

Why is a Trunnion Ball Valve More Suitable for a Sludge Discharge Pipeline?

According to relevant information, within a certain period, a trunnion ball valve can replace gate valves, globe valves, and regulating valves as a tool for transporting fluids. It has good corrosion resistance, wear resistance, and pressure-bearing capacity. In recent years, more and more people inquire about products that are of high quality and low price….

Triple Offset Butterfly Valve

What are Three Eccentricities of Triple Offset Butterfly Valve

The traditional hard sealing butterfly valve has no guarantee of sealing performance and may have a large leakage. In order to improve this situation, the hard sealing butterfly valve has been reformed many times, and the triple offset butterfly valve has been born. The characteristic of triple offset butterfly valve is that the alloy material with high temperature and corrosion resistance…
