Oil Return Pressure Stabilizing Nozzle

Oil Return Pressure Stabilizing Nozzle is a single-fluid pressure atomizing oil spray nozzle that incorporates an internal oil return channel to precisely regulate spray flow and maintain stable fuel pressure. By returning a portion of the oil back to the tank while keeping inlet pressure nearly constant, it delivers consistent atomization performance even when output flow changes. With adjustable spray angles and a wide flow range (20–750 kg/h), this nozzle offers stable oil supply, controlled spray capacity, and reliable mist quality for industrial fuel-spray, heating, and combustion applications.

Application features:

1. The nozzle allows precise flow control through return oil pressure adjustment, enabling accurate regulation of fuel delivery under varying operating conditions

2. Oil Return Pressure Stabilizing Nozzle maintains a relatively stable spray angle with minimal variation, ensuring consistent spray coverage and predictable performance.

3. With stable supply pressure and adjustable flow rate, it delivers consistent atomization quality, maintaining uniform droplet formation across different operating ranges.

4. Multiple flow rate options are available, providing flexibility to meet different system requirements and application needs.

5. The return flow structure improves control accuracy and system efficiency, making it suitable for applications requiring fine adjustment of fuel input.

6. Its optimized internal design supports stable operation under high-pressure conditions, ensuring reliable performance in continuous industrial use.

7. It supports a high turndown ratio (typically 1:3 to 1:5), allowing significant flow variation without compromising atomization quality, which improves system flexibility and control accuracy.
