Excess Flow Valve Operations

The spring loaded poppet remains in the open position during normal system operation. Should an excess flow condition occur downstream, the poppet rapidly moves to the tripped position stopping uncontrolled release of system media. When pressure equalizes through the bleed vent, the spring automatically resets the poppet and opens the valve.
