Flow Control Valve
NU-TECH Flow Control Valves are designed to limit flow rate to an adjustable maximum, maintaining consistent performance across varying conditions.
Automatic Control Valve
Feature
- Easily maintained without removal from the line.
- Replaceable seat ring.
- Heavy-duty, nylon-reinforced diaphragm.
- Operates automatically off line pressure.
- Used in water distribution systems.
- Suitable for filter backwash control.
- Diaphragm assembly guided top and bottom.
Combine Features
- Solenoid (On–Off)
- Pressure reducing
- Hydraulic check
- Pressure sustaining
Operation
- Controls/limits flow to a constant, preset rate regardless of upstream/downstream pressure fluctuations.
- If differential pressure across the orifice plate is below the pilot setting, the valve remains open.
- The pilot and main valve remain closed until manually reset (for break protection scenarios).
- Protects against downstream pipe breaks by isolating flow.
- Senses differential pressure across a factory-calibrated orifice plate, throttling to maintain the field-adjustable flow rate.
- Orifice plate can be installed upstream or downstream—ideal for pressurized pipeline or open-reservoir blending applications.
