Self-Operated Low Pressure Relief Valve

Category:Nitrogen Sealing Valve

        The RJ5000 series self-operated low-pressure relief valve is a pressure relief valve with direct spring action. It is ideal for micro-pressure control of various gases, particularly in micro-pressure nitrogen sealing systems. The valve uses an internal pressure extraction method for fast pressure response and is characterized by high precision, zero leakage, and resistance to pressure differences.

Product Description:

Design features    >>>

1. Safety overload protection: Effectively unloads overload pressure under abnormal conditions, preventing valve damag;

2. Stainless steel actuator: This option enhances the valve's appearance, prevents rust, and improves its stability and longevity;

3. Suitable for corrosion-resistant environments;

4. Modular design: Versatile and easy to replace parts;

5. Special valve body: The valve body features a balanced design to achieve more stable control;

6. High precision: the lowest control pressure is 0.5 KPa;

7. It is suitable for micro-pressure control in front of the valve.
