This internal setting design is a significant departure from traditional pilot-operated pressure regulating valves, offering much better control stability. It features an integrated commander and eliminates the need for the primary pressure reduction and throttling devices commonly found in pilot-operated valves. Pressure adjustment is simplified with a single regulating nut, making it easier to set and maintain.
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. Packing-free design: The valve body and bonnet structure are compact, reducing the overall size of the valve;
4. Modular design: Versatile and easy to replace parts;
5. Special valve body: The internal structure adopts a balanced design for high precision and stable control;
6. High precision: The set pressure-reducing valve and the main control valve operate independently, ensuring stable control without interference. The spring action during high-pressure control generates only a minimal fixed net difference relative to the control pressure, resulting in high control accuracy;
7. Internal setting design: No external pipe design pressure is needed. The valve connects directly to the pipeline and is ready for use;
8. Visual stroke: The design features scale lines on the top of the membrane head so that the opening and closing travel of the valve core can be observed directly;
9. High pressure difference design: The balanced main valve core allows the valve to handle high-pressure differentials effectively;
10. Single setting nut: A single nut on the main control valve allows for easy pressure regulation through a screw adjustment mechanism, making the process faster and more convenient.

Structural characteristics >>>
1. Single setting nut design: It is only necessary to adjust the nut to set the pressure, eliminating the need for throttle valve and primary pressure-reducing valve. This makes the setup and adjustment process quick and convenient.
2. Diaphragm actuator: The high-pressure diaphragm actuator offers less friction and a longer service life compared to piston actuators.
3. Travel indicator: It shows the working status of the pressure regulating valve and helps analyze the responsiveness, sensitivity or fluctuation.
4. Stability control: The set pressure-reducing valve and the main control valve work independently, ensuring stable control without interference.
Notes >>>
When installing the pressure regulating valve, the medium flow direction must align with the arrow on the valve body.
The valve should be installed in a horizontal pipeline, with the actuator positioned vertically upwards.
