Flomatic Corporation introduces their new Model 508S6 Ball Check Valve; a simple, yet reliable 316 stainless steel check valve.

The valve 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, the company said in a press release. 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).

“It was our goal to deliver a longer service life ball check valve; the Model 508S6 does just that,” Bo Andersson, Flomatic’s president, of the new valve, which can be installed both vertically and horizontally. The manufacturer offers an optional Auto-Vac Model 77 vacuum breaker.

Rated at 150 PSI and a maximum 180 F, Model 508S6 may be ordered in 1-1/4 in., 1-1/2 in., and 2 in. sizes.
