Pilot Regulator
Model No. NRV-802
- Ideal as a pilot regulator, such as a large-diameter air-controlled regulator with the ability to maintain the set pressure with high precision.
- The constant bleed system quickly responds to pressure fluctuations on the OUT side to maintain the set pressure.
- The steel ball (SUS) valve prevents long-term changes of characteristics.

Model No. NRV-802D, Model No. NRV-502JD
- Detects the secondary pressure of the main regulator with the feedback circuit to control the pilot pressure.
- Used in combination with a precision regulator (high relief type) with high relief flow rate performance to precisely maintain the set pressure on lines where the flow rate largely fluctuates and an excessive pressure is likely to occur.
