Specifications & product details

REGIONS SUPPLY BUYING GUIDE

Product details & buying advice

Excess-flow selection depends on how the valve and downstream piping work together, including the flow available during a line break.

Product type	Excess flow valves
Part / SKU	A7537P4F

What to check before ordering

Match the service medium, connection, mounting orientation and liquid or vapor closing-flow rating.
Confirm that normal demand stays below the closing rate and that the intended break condition can produce enough flow to close the valve.
Have qualified personnel follow the manufacturer’s installation and functional-test procedure.

Service reminder: Small leaks or restricted downstream flow may not trigger closure. Keep the required shutoff protection and leak-detection provisions in the system design.

Have gas-system installation and service completed by qualified personnel. Use the current instructions for the exact model and the requirements that apply at the installation location.
