335-SS-3-FFF-L-015 Flo-Tite 1/2 Stainless Steel 3 Piece Ball Valves, Multi-Choice Weld-In-Place 335SS

The Flo-Tite 325 / 335 Series is designed as a split body, three-piece construction, to allow ease of access for maintenance of the valve ball and seat without special tools. This line of valves utilizes the "free floating" ball principle. The ball is not fixed but is free to move with the line pressure. As a result, these valves are capable of tight shut off with the flow in either direction or dead-ended, regardless of the position of the valve in the line. The downstream seat, which is opposite the pressurized side of a closed valve, must carry the load exerted by the line pressure on the ball, while the upstream seat is subject to little load or wear. For this reason, it is sometimes possible to increase useful seat life by turning the valve end to end in the pipeline.Features:Safer InstallationReduced LiabilitySave Valuable TimeReduce Labor CostAssures Fool-Proof Installation
