Safety-grade pneumatic quick isolation valve
Main Use and Scope This series of pneumatic quick-closing valves isolates the ventilation system of rooms with potential radioactive contamination in the event of a pollutant leakage accident. In the event of an accident, it cuts off the ventilation system where the isolation valve is located to prevent the spread of fission products. This valve is a device with safety functions. This valve features a reasonable structure, reliable performance, and low leakage.
Main Performance Parameters
Operating Pressure: 380 daPa
Applicable Medium: Air
Medium Temperature: 60°C
Relative Humidity: ≤100%
Valve Size: 800×1400
Valve Leakage Rate: Under 400 daPa, the internal leakage rate of the valve does not exceed 15 m³/h.m²; the external leakage rate is 0.
Fully Open Valve Resistance Coefficient ≤1
Drive Type: Pneumatic
Radiation Resistance Accumulated Dose: 1 × 10⁴ Gy
Nuclear Safety Level: LS
Quality Assurance Level: Q2
Seismic Resistance Level: 1A
