Nozzle Check Valve for Non-Slam Flow Control
1. Quick Overview Our nozzle check valve, also known as a non slam check valve or axial flow check valve, is designed to prevent reverse flow while eliminating water hammer in pipelines. Unlike traditional swing or lift check valves, nozzle check valves use a spring-assisted axial disc that closes instantly and smoothly. This makes them […]
Tilting Disc vs Silent Check Valve Comparison
Quick Summary Comparing tilting disc vs silent check valve is not simply a matter of preference. Each design behaves very differently under real operating conditions such as flow velocity, pressure fluctuation, and pump shutdown. At Vcore Valve, we often help engineers avoid costly mistakes by understanding how these check valves truly perform in service, not just […]
Lift Check Valve Structure, Working Principle & Applications
Quick Summary A lift check valve is one of the most reliable solutions for preventing reverse flow in pressurised pipeline systems. Unlike swing-type designs, it operates through vertical disc movement driven purely by flow dynamics and gravity. In this guide, Vcore Valve explains the structure, operating behaviour, performance characteristics and real-world applications of lift check […]
Sump Pump Check Valves: Types, Benefits & Applications
🔍 Quick Overview Sump pump check valves play a critical role in preventing backflow, protecting pumps, and improving drainage efficiency. Without a properly selected check valve, sump systems suffer from short cycling, water hammer, and premature pump failure. In this guide, Vcore Valve explains the main types of sump pump check valves, how they work, […]
Vacuum Breaker vs Check Valve: Key Differences Explained
Quick Overview In fluid systems, backflow is not just inconvenient—it can be dangerous. Two common devices used to prevent it are vacuum breakers and check valves. While they often appear to serve the same purpose, their working principles, applications, and limitations are very different. At Vcore Valve, we regularly help customers choose between these two […]
What is swing check valve
Quick Summary A swing check valve is a type of backflow prevention device used in pipelines to ensure unidirectional flow. The valve has a hinged disc that swings to allow flow in one direction, and swings back to close when flow reverses. This simple yet effective mechanism prevents backflow and protects systems from potential damage […]
