The spring loaded safety valve uses spring force to balance medium pressure. When pipeline pressure exceeds the set value, the disc lifts automatically to discharge excess medium and reduce system pressure. When pressure returns to normal, the valve closes automatically. Products are available with full lift and low lift designs. Various materials and sealing options are offered to adapt to different temperature, pressure and medium conditions. Widely used for overpressure protection in petroleum, chemical, natural gas, power and boiler systems.

The pilot operated safety valve consists of a main valve and a pilot valve. System pressure controls the opening and closing of the main valve through the pilot valve. It features high set pressure accuracy, stable performance, excellent tightness under normal working pressure and small blowdown. Suitable for large-diameter and high-pressure working conditions. Multiple structural and material options are available to adapt to various media. Widely adopted for overpressure protection of pressure vessels and pipelines in petroleum, chemical, natural gas and power industries.
