The 9707R Pressure Independent Control Valve (PICV) is engineered for precision flow regulation in dynamic HVAC environments. Manufactured with dezincification-resistant (DZR) brass, this valve ensures long-term durability and exceptional corrosion resistance in hydronic systems.
Designed to maintain constant flow regardless of pressure fluctuations, the 9707R integrates a flow regulation assembly, diaphragm mechanism, and presettable dial—delivering +/-5% flow accuracy and 100% full stroke modulation. This valve supports manual presetting and is actuator-ready with M30x1.5 threads, ensuring seamless integration with building automation systems.
Ideal for commercial and residential HVAC balancing, the 9707R helps optimize energy efficiency, comfort, and system performance.
Key Features:
- Pressure-Independent Design: Maintains constant flow under varying system pressures
- Full Stroke Modulation: 100% actuator stroke regardless of preset flow rate
- Accurate Flow Control: ±5% of max flow or ±10% of set flow, whichever is greater
- Dial-Based Presetting: Quick and secure flow rate adjustment
- Threaded M/M Ends (NPSM): ASME B1.20.1 compliant for easy installation
- Actuator-Ready: Compatible with M30x1.5 threaded linear actuators
- With Test Points: For fast and accurate differential pressure readings
- 300 WOG Rated: Suitable for demanding applications
- Temperature Range: 15°F to 260°F (with antifreeze/anti-boil additives)
