Ball valve

Hayward’s new plastic, corrosion resistant lateral three-way ball valves simplify piping system layouts by replacing conventional valve/tee connection combinations. The new valve can also be used to replace zero dead-leg valves. The valves are available from 1/2" to 6" made of PVC or CPVC with a choice of FPM or EPDM seals. The valves feature a specially designed ball that permits the flow to be diverted from the center port to either the left or right ports without a shutoff position.

Odor control

Altivia offers Nitrazyme™ Plus, a proprietary (Patent pending) blend containing sodium nitrate. The product is a safe, natural biological approach to controlling odors and corrosion produced from reduced sulfur compounds in wastewater. Nitrate provides a source of bound oxygen (nitrate-oxygen) to naturally occurring facultative anaerobic denitrifying bacteria present in wastewater, which these bacteria metabolize preferentially over alternative sources of oxygen such as sulfate, preventing the formation of H2S gas.
