Resideo Braukmann vp526a1068 Three-way Unitary Pneumatic Mixing Valve 3/8 Inches 1.0 Cv

Product Description

The Resideo Braukmann VP526A1068 is a 3/8 inches three-way unitary pneumatic mixing valve with a flow capacity (Cv) of 1.0. It is designed for proportional control of hot and cold water in unit air conditioners and fan coil systems. HVAC technicians and building automation professionals rely on this type of mixing valve to regulate water flow and maintain precise temperature control across hydronic systems. The VP526A1068 uses a direct-acting, rolling diaphragm actuator that responds to pneumatic signal changes within a spring range of 3 psi to 10 psi. This actuator includes an integral high-temperature plastic air connector sized for 1/4 inches O.D. plastic tubing, making field connections straightforward and reliable. The valve body is a three-way configuration, which allows it to blend or divert flow between two inlets and one outlet, or one inlet and two outlets depending on system design. This makes it well suited for fan coil units and other terminal HVAC equipment where water mixing and zone-level temperature control are required. The VP526A1068 features brass seats, including an integral lower seat and a removable upper seat, paired with a contoured plug that provides metal-to-metal seating for reliable shutoff and long service life. The stainless steel stem adds durability in wet hydronic environments. Packing is a spring-loaded, self-adjusting Buna-N V-ring type that is field replaceable, reducing downtime during maintenance. The valve delivers linear and constant total flow throughout full plug travel, which supports accurate and consistent control performance. It handles fluid temperatures from 35F to 250F, making it compatible with both chilled water and hot water systems. The compact 3/8 inches body size allows installation in tight mechanical spaces where larger valves would not fit. This valve also serves as a direct replacement for units from Johnson, Powers, Robertshaw, Barber-Colman, and older Honeywell devices, making it a practical retrofit solution for existing pneumatic control systems.
