The Aggroball valve from YGROS has been specially engineered for handling aggressive materials with increased chemical resistance. Featuring the springless technology meaning it is maintenance free, this check valve is suitable for horizontal, vertical up and down installation (even in vertical pipes with flow down).
YGROS patented technology sets new standards in the world of plant design, thanks to a patented magnetic principle replacing the conventional spring in non-return valves and is suitable for fluids and steam.
