Fusion 4000 Independent Channel Syringe Pump Using Check Valves for Continuous Flow
A check valve is a valve that normally allows fluid (liquid or gas) to flow through it in only one direction. Check valves are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave. Utilizing a check valve with a syringe, you can run a continuous cycle experiment at Chemyx Fusion 4000 syringe pump. See the picture below for the ...

Sanitary Check Valves Astonishing Features
Sanitary check valves are mainly used to prevent the backflow of fluids. These valves only allow the flow in one direction. They are usually very small and simple. As the name suggests, they are designed to maintain a high level of hygiene while maintaining a continuous flow of the medium. These valves are mainly used for highly viscous liquids such as gels and ice cream. Sanitary check valves ...

Don’t Just Replace a Check Valve, Upgrade It!
Just over 300 miles northwest of Santa Monica, CA, where the world’s first marine outfall was installed in 1910, check valves are being re-designed and engineered for outfalls all over the world. Outfalls – which are essentially discharge points of a waste stream into rivers, drains, sewers, or other bodies of water – are located in thousands of places across the planet. Many of ...

Fascinating Features of Sanitary Check Valves
Sanitary check valves are mainly used to prevent the backflow of fluids. These valves only allow the flow in one direction. As a matter of fact, they are one of the few valves that have been self-automated to open and close with no assistance. Unlike other types of valves, check valves continue to work even after the plant has lost air, electricity or manual control from the operation team. They ...

Sanitary Check Valves Principles and Parameters
The sanitary check valve will open when the media flows forward and will close when the medium returns to flow. These are mainly automatic valves, whose main function is to prevent the backflow of the means, as well as to avoid the inversion of the pump and the drive motor and the release of the container means. It is also used for safety protection in auxiliary systems where the pressure can ...

Swing Check Valve vs. Spring Check Valve
Valves are versatile devices used for controlling the flow of liquids or gases. They play an important role in countless piping and process systems, typically serving to regulate flow and pressure, start or stop flow, or prevent the occurrence of back flow within a system. Swing check and spring check valves are two relatively common valve types that have broad applications. Swing check valves ...

How to eliminate water hammer when pumping at high velocities
The Importance of Check Valves Check valves are common throughout industries where fluids are pumped through piping systems. These are passive, one-way valves, ensuring the forward flow of fluids before closing to prevent backflow conditions. Check valves are available in a wide range of sizes, materials and styles including swing, double-door, ball, diaphragm and duckbill types. They are ...

How to prevent standing water with unique new check valve
What is a Check Valve and Why is it Useful? Check valves are used in all stormwater and wastewater systems. They allow the forward flow of fluids before closing to prevent backflow conditions. These valves come in a variety of diameters and designs, including swing, ball, diaphragm and duckbill check valves. They are simply designed, passive devices that rely on flow velocity and pressure to ...

Learining how to Choose Materials for Gas Valves
The materials and the quality of gas valves are so important that their disqualification will lead to leakage in-or-outside the body of the valve. If the strength, rigidity and overall performance of the components of the valve body cannot meet the requirements or even break, it will result in the spillage of gas and explosion. Therefore, material and quality are the most critical part during the ...
