The 2nd generation of the Schenck Process PT45 Diverter Valve 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-degree 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. The housing and tunnel on the aluminum valve are hard anodized for wear resistance. To complete the unit, a pneumatic actuator providing a 2 to 4 second actuation time between ports, a 4-way double solenoid air control valve with a NEMA 4 enclosure, and a NEMA 4/4X position proof switch with 2 DPDT switch elements are included. 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.
