Explosion-proof valve

FB series-pipe explosion-proof valve

1.Structure and symbol

1								2								3								4
Spool								Hole pin								Spring								Valve body

2. Operation

Under pressure,the fluid flows from 1 to 2.After the valve core is closed,the fluid passes through the damping hole,resulting in a rapid decrease in flow rate.
