Application
VB-9313 series 3-Way mixing valves control hot or chilled water in heating or air
conditioning systems. These valves must be piped with two inlets (“A” and “B” ports)
and one outlet (“AB” port). They are used for two-position or proportional control
applications. Valve assemblies require an actuator and a valve linkage that may be
factory or field assembled.
Features
• Valve sizes 2½”…6”.
• 125 psig pressure rating per ANSI Standards (B16.1–1993) for flanged cast iron
bodies.
• Spring-loaded TFE & EPDM packing.
