Being based on quality, strengthening management, continuous improvement, and customer first.
Performance:
1. The allowable tolerance of the set pressure:≤±3% of the set pressure.
2. Overpressure:≤±10% of the set pressure.
3. Blowdown:≤±15% of the set pressure.
4. Tightness: The valves have good seat tightness, conforms to API STD 527.
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 woth 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 nozzle seat is deposited with Stellite. Excellent flatness and surface finish of the seating surfaces by precision machining and lapping assure safety valve to have high degree of seat tightness and long using life.
6. The bellows of balanced bellows safety valves 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 materials is careful. The manufacture of the spring and the bellows has strict technological process. Each of them is tested and checked strictly.
