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	1519A2

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.

Overview

Engineered Controls 1519A2 – 1" NPT Excess Flow Valve (25 GPM, LP Gas Liquid/Vapor)The Engineered Controls 1519A2 is a heavy-duty 1" NPT excess flow valve designed for liquid or vapor service in propane (LP gas) and other compatible industrial gases. Ideal for long piping runs or branch lines where tank-mounted excess flow valves are not sufficient, this precision-machined brass valve provides superior flow protection and long-term reliability.

Rated at 25 GPM (propane liquid), this valve features large internal flow channels designed to minimize pressure drop while delivering fast, reliable excess flow closure. A cotter pin secures the spring retainer against vibration, making this unit suitable for transport, bulk plants, cylinder filling, and high-duty industrial applications.

The stainless steel spring ensures consistent closing characteristics and extended service life, even under demanding flow or vibration conditions. Wrench flats (1-3/4") provide secure installation in any orientation — vertical, horizontal, or inverted.
