Product features

A full-lift safety valve is designed so that the disc lifts sufficiently to ensure that the curtain area no longer affects the discharge area. The discharge area, and consequently the valve's capacity, is determined by the bore area. This configuration is achieved when the disc lifts a distance of at least a quarter of the bore diameter. For general steam applications, a full-lift conventional safety valve is often the optimal choice. The opening height of a full-lift safety valve is more than one-fourth of the flow diameter, which significantly enhances its discharge capacity. This feature provides a substantial advantage in terms of efficient and rapid release of pressure.
