ZHEJIANG SHANGFENG SPECIAL BLOWER INDUSTRIAL CO.LTD
Safety-level regulating valve
Main Use and Application Range:
Used in ventilation and air conditioning systems related to nuclear safety in nuclear power plants (not applicable to ventilation systems operating under water loss conditions inside the containment). Controls temperature or humidity by adjusting the valve opening; maintains system pressure difference or pressure; adjusts system flow rate; and acts as an isolation and shut-off function at the inlet and outlet of air conditioning units and air purification units.
Drive Type: Electric adjustment.
Product Parameters:
Specifications: 1600×1250 mm
Design Pressure: 5000 Pa
Accumulated Radiation Dose: 2×104 Gy
Nuclear Safety Level: Safety Level 3
Seismic Category: SSE
Valve Fully Open Resistance Coefficient: ≤1
External Leakage Rate: ≤1.7 m3/h.m2 (under 250Pa pressure)
Internal Leakage Rate: ≤115.7 m3/h.m2 (under 2500Pa pressure)
