Flow Control valve
NU-TECH Flow Control Valves are designed to limit flow rate to an adjustable maximum.
- Easily maintained without removal from the line.
- Replaceable seat ring.
- Heavy-duty, nylon-reinforced diaphragm.
- Operates automatically off line pressure.
- Used at water distribution system
- Used at filter backwash control.
- Diaphragm assembly Guided top and bottom.
- It is designed to control or limit flow to a constant, predetermined rate regardless of fluctuation in upstream and downstream pressure.
- Differential pressure across the orifice plate is less than the pilot setting , the valve remains open.
- The pilot and main valve remain closed until manually reset.
- It protecting against a break in the downstream pipe
- Senses differential pressure across a factory-calibrated orifice plate, then accurately throttles to maintain field-adjustable flow rate
- Orifice plate can be installed downstream or upstream, making it ideal for pressurized pipeline or open reservoir water-blending applications
- Solenoid (On-Off)
- Pressure reducing
- Hydraulic check
- Pressure sustaining
