Solids-handling diverter valve has new features
The second generation of the PT45 Diverter Valve (photo) introduces new features, such as adjustable alignment stops located in the housing, position indication from the tunnel itself, additional actuation options and external tunnel-position indication. A positive food-grade rubber silicone seal at each port is designed to help prevent contamination. Additional features include 45-deg port-to-port rotation, a two-way switching capability for either dilute-phase or dense-phase conveying applications, cast iron or aluminum housing, tunnel, and end plates with a 316 stainless-steel actuator and arm assembly, and inlet and outlet ports flanged to mate 150# ANSI flange patterns. Also included are a pneumatic actuator providing a 2–4-s actuation time between ports, a four-way double solenoid air control valve with a NEMA 4 enclosure and a NEMA 4/4X position proof switch with two DPDT switch elements. High-temperature designs, electric actuators and cast 316 stainless steel housing, tunnel and end plates are also available options with the new version of the PT45 Diverter Valve. — Schenck Process, Whitewater, Wis.
