The ZPL630F (ZZYVP) pilot-controlled self-acting pressure regulator requires no external energy supply. It utilizes the energy of the controlled medium itself as the source, introducing it into the valve's pilot to control the position of the main valve plug, thereby changing the throttling area. This adjusts the medium flow rate through the regulating valve and stabilizes the downstream pressure.
Pressure setting is achieved by adjusting the spring on the pilot, making the process convenient, quick,labor-saving, and time-efficient. It allows continuous setting during operation, with a simple structure and minimal maintenance workload. Boasting a pressure reduction ratio of <4000:1, high control precision, sensitive action, and excellent sealing performance, it is widely applied in automatic pressure reduction and stabilization control of gases in various industrial equipment, and is particularly suitable for nitrogen blanketing systems of storage tanks. A globe valve is included as an accessory. Before the valve operates, this globe valve must be closed to prevent overpressure and impurities from entering the actuator, thus protecting the diaphragms and seals inside the actuator and avoiding damage to the entire valve due to overpressure.

| Features | Description |
| Power-Free & Auto-Regulation | No need for external energy input, utilizing the energy of the controlled medium itself as the power source. Through a pilot that detects and controls the actuator, it precisely adjusts the valve plug position to modulate the medium flow rate, thereby maintaining constant downstream pressure. |
| Adjustable Operation | The pressure setpoint can be conveniently adjusted directly on the pilot valve, allowing for continuous in-process calibration without system shutdown |
| Modular Structure Design | This regulator features an innovative compact design with fast response. It eliminates the need for downstream pressure tapping (optional tapping ports are available if required), ensuring easy installation, wide pressure adjustment range, and positive shutoff |
| Micro-Pressure Sensing Capability | The ZPL630 Self-operated Pressure Regulating Valve (Nitrogen Supply Valve) delivers highly responsive actuation and precise control. Its oversized pressure-sensing diaphragm and low-stiffness setting spring ensure exceptional sensitivity. The packing-free design minimizes stem friction, enabling fast response and high-precision regulation |
