    Description

    API 526 Pressure Relief Valves


    Performance:

    The allowable tolerance of the set pressure: <+/-3% of the set pressure
    Overpressure:<10% of the set pressure
    Blowdown:<15% of the set pressure
    Tightness: the valves have good seat tightness, conforms to API527

    Features:

    1)The solid nozzle screws into the body. its maintenance is easy
    2)The shape of the disc holder has been designed to enhance the effect of the fluid thrust for an instant lift of the disc
    3)Blowdown control is provided with adjustable nozzle ring only
    4)The adequate materials and clearance between disc holder and guide, spindle and adjusting screw assures disc to lift successfully.
    5)The surface of both the disc and the nozle seat is depsited with STL. Excellent flatnes and surface finish of the seating surfaces by precision machining and lapping assure safety valve to have high degree of seal tightness and long usage
    6)The bllows of balanced bellows safety valve not only can avoid and effect of variable back pressure in the system, but also can protect spring and other trim components from corrosive media
    7) The choice of material is careful. The manufacture of the spring and the bellows has strict technological process. Each of them is tesed and checked strictly.
