Excess Flow Valves

Introduction

If downstream line ruptures, the excess flow valve can stop uncontrolled release of system media. When the system is

functioning normally, the working element remains in the open position. If the excess flow occurs downstream, the working

element quickly moves to the tripped position to stop bleeding. When system pressure reaches balance through the bleed vent,

the spring resets the working element to the open position automatically. The flow which goes through the bleed vent should

be lower than one percent of the flow rate in the trip range.
