The S-1100NL no lead full port ball valve features a sweat end configuration and a waste drain, making line maintenance more convenient than conventional means. It also utilizes the blowout-proof Viton dual o-ring stem design, complete with a tamper-evident locking seal. The Dyneon TFM PTFE seats reduce actuation torque, providing a smoother experience when paired with the self-cleaning chrome-plated ball. The S-1100NL also has a corrosion-resistant Dacromet-coated steel handle.
