Flomatic® Corporation has introduced their new Model 508S6 Ball Check Valve; a simple, yet reliable 316 stainless steel check valve. Among others, it features a full-ported valve seat uniquely designed to allow a strong phenolic ball to seat on a Nitrile (Buna-N) seat. For vacuum or anti-flooding valve applications, an optional floating rather than sinking ball is used.
Due to its simple flow efficient design, the valve is virtually maintenance-free. This valve is commonly used in submersible wastewater lift station applications. The optional vacuum breaker mounted on the access port reduces hydraulic shocks (water hammer).
