Zero-leakage closed isolation valve
Main Uses and Applications:
Electrically-actuated airtight isolation valves are used in the ventilation systems of nuclear power plants, where they serve to isolate airflow. They are characterized by their light weight, low flow resistance coefficient, and short operating time.
Main Performance Parameters:
Design Pressure: ≤4000Pa
Applicable Medium: Air
Medium Temperature: ≤107℃
Valve Size: 1250×1250
Internal Leakage Rate of Valve: At ΔP=4000Pa, internal leakage is zero; external leakage is zero.
Resistance Coefficient of Fully Opened Valve: ζ≤1
Drive Type: Electric
Nuclear Safety Level: F-SC1
Quality Assurance Level: Q2
Seismic Resistance Level: SSE1
