VG1600 Series 270° Six - Way Valves Product Bulletin 1 VG1600 Series 270° Six-Way Ball Valves Product Bulletin Code No. LIT-12012567 Issued August 2017 VG1600 Series 270° Six-Way Ball Valves are designed to regulate the flow in an easy and most efficient way of both hot and chilled water in response to the demand of a controller in HVAC systems. The 270° Six-Way Valve substitutes either four through valves or two through valves and one change-over valve. The VG1600 is supplied with control flow disk providing the right flow rate for a wide range of applications. Available in sizes ½’’ and ¾’’ inches, the valve is operated by a 270° rotary proportional actuator non spring return. The coupling between valve and actuator is designed as a fool-proof mounting system in order to ensure quick installation reducing the risk of installation mistakes. Benefits National Pipe Thread (NPT), British Standard Pipe Parallel (BSPP) and Sweat Union Fittings Provide the right valve for a broad range of applications, reduce installation time while reducing the need for adapters, and increase system reliability Forged Brass Body Provides PN16 (300 psi) static pressure rating 350kPa (50 psi) Closeoff Pressure Rating Provides tight shutoff Stainless Steel Ball and Stem Assembly Tolerates high temperature water where a higher degree of corrosion protection is desired Ethylene Propylene Diene Monomer (EPDM) Double O-Ring Stem Seal Provides a leak-free seal; the packing has been tested and is leak-free after 100,00 cycles in iron-oxide contaminated water Graphite-Reinforced Polytetrafluoroethylene (PTFE) Seats Include 15% graphite-reinforced ball seats, providing better wear resistance Maintenance – Free Design Performs without failure in excess of 100,00 full stroke cycles in iron-oxide contaminated water Wide Selection of Styles for a Variety of Applications Offers various valve configurations with just one valve size Factory- Mounted VA9905 Series Electric Actuator Reduce installation time, thus reducing overall installation cost VG1600 Series 270° Six - Way Valves Product Bulletin 2 PRODUCT OVERVIEW APPLICATION VG1600 Series 270° Six-Way Ball Valve is the easiest and the most efficient way to control both heating and cooling operational modes. The true close-off feature, which is internal to the valve, isolates the heating circuit from the cooling circuit. This eliminates up to four valves and two actuators or three valves and two actuators depending upon the terminal equipment system installation. Eliminating these components leads to lower installation costs for terminal equipment systems using this new technology.

Heating and cooling flow rates are different due to their different ΔT project. The VG1600 is supplied with control flow disks which involves 4 couples of changeable disks made by PSU. The available control flow disks have a color code (red for heating operational mode and blue for cooling one) that provides intuitive indications for use with the respective side of valve. Each disk has clearly marked its corresponding Kv/Cv value. The final user can select the suitable Kv/Cv for each side by installing the appropriate disk. They are installed or removed using the ring nut provided in the kit. It is recommended to put the disks for Kv/Cv management on the return ways. Once the appropriate disk is fitted in the valve, the rest of the flow control disks can be retained on the actuator or valve if at any time in the future any change is required. There is just one item per valve size, and then with the different disks the combinations can cover any customer need, simplifying the valve choice and reducing the operational cost. The disk is hold by a ring nut with the provided tool of the set. The flow control disk is available as separated accessory.

Use this diagram as a guide on how to attach a VG1600 Series Valve to your system. Note: Valve port 2 must only be used as coil supply. Valve port 3 must only be used as coil return. VG1600 Series 270° Six - Way Valves Product Bulletin 7 • Over Pressure System: The 270° Six - Way Control Valve is designed to prevent any damage in the terminal unit circuit. When the valve is in close position (for both cooling and heating operating modes) the trapped fluid may varies its pressure due to changes in ambient temperature. The pressure compensation system has to relieve such pressure changes. In order to connect the terminal unit circuit with either the sequence 1 or 2 circuit (expansion vessel), the upper valve is designed with no gasket need, while the lower valve provides a true close off. When the valve is in closed position the water flows inside the upper ball, going inside the inlet of the terminal unit since there is no gasket that prevents it.
