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	A8574AG

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.

Product Description

RegO A8574AG 4″ Multiport Pressure Relief Valve Manifold with (4) A3149G ASME Relief Valves – 250 PSIG

This RegO A8574AG Multiport pressure relief valve manifold is designed for use as a primary pressure-relief assembly on large stationary pressurized storage containers.

The assembly includes four A3149G pressure relief valves, each with a 2-1/2″ male NPT inlet, and is designed for connection to a 4″–300# container flange. The manifold allows one relief valve to be isolated for service or replacement while the remaining relief valves continue providing pressure protection for the container.
