ZHEJIANG SHANGFENG SPECIAL BLOWER INDUSTRIAL CO.LTD
Safety check valve
Main Use and Application Range:
The check valve is installed at the outlet of the fan. When the fan is running, the positive pressure formed before the valve opens the valve plate; when the fan stops, due to the loss of positive pressure and the action of the counterweight and the weight of the valve plate, the valve automatically closes to prevent backflow in the system.
Product Parameters:
Design Pressure: 5000 Pa
Accumulated irradiation dose: 5×104 Gy
Nuclear Safety Level: LS Seismic Category: 1A
Valve fully open resistance coefficient: ≤1
External leakage rate: ≤0.01 m3/h.m2 (under 4000Pa pressure)
Internal leakage rate: ≤200 m3/h.m2 (under 2000Pa pressure)
