Hangzhou valve focuses on scientific and technological innovation and cooperation in production, learning and research. Currently, it has more than 70 national patents, including temperature reduction and pressure reducing devices, safety valves, among which, 8 patents are invention.
LARGE SIZE SAFETY VALVE
HFAs48Y is especially designed with large size from DN250 (10") up to DN600 (24"), the valve is suitable for low and medium set pressure saturated steam applications. Its set pressure range is <2.5 MPa, maximal working temperature <427 DegreeC, suitable for most power plant LP steam line service with larger capacity where needed.
Types: Coventional safety valve
Large orifice is adoptive for larger capacity purpose.
