Frequently Asked Questions
Ductile Iron QT450-10 offers 20% higher strength than carbon steel (ASTM A216 WCB) and superior ductility, which prevents cracking under pressure fluctuations and extreme temperatures down to -10°C.
Unlike swing check valves that use a single large disc, our design uses multiple smaller balls in a porous cone. This allows fluid to flow through multiple channels simultaneously, reducing turbulence and hydraulic loss by 35%.
Yes. The balanced multi-ball design ensures the valve functions reliably in both horizontal and vertical orientations, eliminating the gravity-based restrictions found in traditional swing check valves.
We provide EPDM and NBR rubber coatings for the balls. EPDM is typically used for water and steam applications, while NBR is preferred for oil and chemical media to ensure a watertight seal.
Our flanged ball check valves are designed to handle working pressures up to 2.5MPa (PN25), with shell tests conducted at 1.5x the rated pressure to ensure absolute safety.
The multi-channel porous structure is specifically engineered to resist clogging. It handles moderate slurries and particle-laden fluids far more effectively than single-disc valves, reducing the risk of operational failure.
