Electronic Pressure Independent Valves (ePIV)
Applications Water-side control of heating and cooling systems for AHUs and heat pumps. Equal Percentage: Heating / cooling applications. Linear Characteristic: Bypass control. Mode of Operation The Electronic Pressure Independent Control Valve is a two-way valve which is unaffected by pressure variations in a system. Product Features Constant flow regardless of pressure variations in the system. Maximizes chiller ?T, preventing energizing additional chillers due to low ?-T. Simplifi ed valve sizing and selection, no Cv calculations required. | 1. | Pressure independent valves compensate for pressure variations, performing a continual balancing function to maintain system performance at varying loads. | | 2. | Precise flow control eliminates over-pumping and provides favorable energy savings. | | 3. | Equal percentage flow characteristics leads to system controllability. | | 4. | Pressure independent valve prevent energizing additional chillers by maintaining desirable Delta T. | | 5. | Constant flow performance significantly reduces actuator movement, providing less hunting and wear on the valve assembly. | | 6. | Pressure independent valves are selected based on coil flow rate and no Cv calculations are needed. |
