MPF155-SS-L-FFG-L-100-M14 Flo-Tite 4" Stainless Steel Multi-port Ball Valves, Bottom Entry Series MPF 155

The Flo-Tite Flanged Series are designed as one-piece body. 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-for-end in the pipeline.

Flo-Tite’s Bottom Entry Series provides piping system engineers greater design flexibility. Making the fl o-tite valve a valuable choice for a multitude of unique applications.

Design Features:

Flo-Tite's Bottom Entry Series 3-way ball valves feature a floating ball design with the valve stem in the center between the flanged ends. This valve is ideal to replace plug valves. The compact size, lower weight, ease of maintenance, and reduced cost of these ball valves offer an excellent alternative to the traditional plug valve. The one-piece bodies are constructed of high-quality Carbon Steel or Stainless Steel as standard. Special body alloys are also available upon request.

Other features include replaceable seats and seals, and an optional Media Containment unit. Live-loaded, self-adjusting stem seals automatically adjust to compensate for changes in temperature and wear.

Available Fire Safe Design. All Bottom Entry Series valves can meet fire safe standards for external leakage only. Additional safety features include internally loaded blow-out proof stems and locking devices to prevent accidental movement of ball position.
