VB-F Three-Way Mixing & Diverting Valves FEATRES SPECIFICATION DATA Mixing or diverting models Bronze body with female, screwed-end connections or cast iron body with flanged-end connections Stainless steel stem and replaceable seats Spring loaded, self-adjusting packing Constant total flow throughout full plug travel inear flow characteristic for each port Suitable for pneumatic or electric/electronic actuation Repacking kits available for field servicing RC GENERA V Series Three-Way Mixing and Diverting Valves ( Valves ) provide proportional or two-position control of hot or cold water in heating or cooling systems. They can be used for mixing service (VB, D, and F) to direct flow from one of two inlets to a common outlet or for diverting service (VC and E) to direct flow from a common inlet to one of two outlets. Mixing and diverting Valves are not interchangeable. Copyright 99 Honeywell Inc. All Rights Reserved --
