Valve Pressure Units Explained: MPa vs Bar vs PSI
Quick Overview Understanding valve pressure units is critical when selecting, specifying, or operating industrial valves. MPa, bar, PSI, and kg/cm² are often used interchangeably, yet incorrect conversion can lead to undersized valves, safety risks, or compliance failures. This guide from Vcore Valve clearly explains how these pressure units relate, how to convert them accurately, and […]
Butterfly Valve Disc Material Selection Guide
Compare common butterfly valve disc materials—including epoxy-coated ductile iron, stainless steel, aluminum bronze, and coated discs—by corrosion resistance, mechanical strength, operating torque, temperature capability, cost, and media compatibility. Epoxy-coated ductile iron suits water and HVAC systems, stainless steel is preferred for chemical and hygienic service, and aluminum bronze provides strong seawater resistance for marine and offshore applications
Tilting Disc vs Silent Check Valve Comparison
Compare tilting disc and silent check valves by closing mechanism, pressure loss, water-hammer control, installation space, noise level, and application. Tilting disc check valves provide low flow resistance for large, steady-flow pipelines, while spring-assisted silent check valves close rapidly to reduce reverse flow, noise, and pressure surges in pump discharge systems.
