A Simple Dependable Way to Divert Flow to Two Pipe Lines with Tight Shut-off to Either Line.
D51 diverter valves are designed to accept media through a bottom inlet port and direct it out either of two outlet ports. They are commonly used for alternately diverting flow from a single source to two different lines; for example, dumping operations in which one outlet permits media to flow from a common source to the process while the other outlet alternately dumps or recirculates excess media.
Ball porting for D51 diverter valves is referred to as Vl for 90o valve operation. Flow from the bottom inlet port cannot be shut off, only diverted to either of the two outlet ports. At either end of the valve stroke, however, one port is wide open and the other is shut off bubble-tight. Patented relief slots assist in sealing and reduce torque. The ball is forced into the seat of the blocked port under pressure to affect and maintain a tight seal.
Series D51 Options
V2 porting for 180o full shut-off operations and T51 3-way valves for
bi-directional flow applications are available through Custom Products.
Automation
D51 flanged diverter valves may be automated with Series 75 electric actuators
or Series 39 double piston pneumatic actuators. Both actuators may be used in on/off or
modulating applications. Limit switches, feedback potentiometers, 4-20 mA circuit boards providing remote indication of valve position and other accessories including a full line of advanced positioners are available.
