The RJ3000/4000 series self-operated regulating valve is a versatile pressure-regulating valve with direct spring action. It can be used for control before or after the valve and is widely applied in low-corrosive gas and low-viscosity liquid environments. It is a high-precision, long-life valve.
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. Sliding friction-free design: The valve stem incorporates a long bellows structure, and is supplemented with a backup seal, ensuring reliable sealing at the valve stem and greatly improving the valve's sensitivity;
4. Modular design: Versatile and easy to replace parts;
5. High precision: The bellows valve stem reduces friction compared to traditional packing structures. Optimized spring and actuator designs enables the best combination that guarantees the best performance for precise pressure control.
