In the current check valves, it is common that, because of the usage of the support where the clapper shaft goes, it is produced a constant wear and a short useful life. On the other hand, as it is manufactured in gray casting and not in ductile, it is damaged as a result of the frequent clapper hammers against the body. In some cases the clapper can even be broken, reaching pieces of it to the pump blades and producing irreparable damages.
• As it incorporates bronze bearings and stainless steel shafts, it is avoided the friction against the body, which extends the useful life of the valve.
• Its body is made in ductile casting, allowing to support a higher traction and flexibility, making it more resistant to clapper hammers.
