Product Description

REGIONS SUPPLY BUYING GUIDE

Product details & buying advice

Select container relief equipment from the tank requirements, including the discharge setting and relieving capacity.

Product type	Tank pressure relief valves
Part / SKU	3131G

What to check before ordering

Check the container type, service medium, connection and required start-to-discharge setting.
Confirm sufficient relieving capacity and the outlet protection or discharge arrangement specified for the model.
Use qualified service personnel for inspection and replacement, with both the tank and valve instructions available.

Service reminder: Keep tank relief and trapped-liquid line relief separate in your parts selection. A matching thread does not make those valves interchangeable.

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.
