Pressure Independent Control Valve | 9707R Series | DZR Brass
Pressure Independent Control Valve | 9707R Series | Threaded M/M with Test Points | 300 PSI WOG
9707R Pressure Independent Control Valves (PICVs) ensure precise flow control and system balance in dynamic HVAC and hydronic environments. Built from dezincification-resistant (DZR) brass, this valve delivers exceptional corrosion resistance and long-term reliability in heating and cooling systems.
Engineered for constant flow performance regardless of pressure fluctuations, the 9707R integrates a dynamic flow regulation assembly, diaphragm mechanism, and presettable dial to maintain ±5% accuracy and full-stroke modulation. Each valve includes test points for pressure verification and supports actuator mounting via M30x1.5 threads.
Key Features & Benefits
- Pressure-Independent Operation — Maintains constant flow despite differential pressure changes.
- 100% Stroke-Independent Modulation — Full actuator stroke range regardless of presetting.
- Flow Accuracy ±5% — Ensures stable performance and efficient hydronic balancing.
- Manual Presetting Dial — Simple push-and-rotate scale allows quick, tool-free flow adjustment.
- Test Points Included — Red and blue color-coded ports for fast and accurate system measurement.
- Threaded M/M Ends — NPSM threads per ASME B1.20.1 standard ensure reliable connection.
- Actuator Ready — Compatible with standard M30x1.5 linear actuators for automated control.
