Closing Flow Rates

The clsoing flow rate of the excess flow valve is dependent on the order that the valve guide and spacer components are inserted in the excess flow valve during the assembly / maintenance.

500 MACFD

Placing the spacer prior to placing the valve guide in the excess flow valve maximizes the travel distance of the poppet head to the valve seat, thus yielding a closing flow of 500 MACFD

300 MACFD

Placing the spacer prior to placing the valve guide in the excess flow valve maximizes the travel distance of the poppet head to the valve seat, thus yielding a closing flow of 300 MACFD
