Rego LV404Y9 & Compact LV404Y39 2PSI Regulator

The LV404Y9 / LV404Y39 is a twin-stage propane regulator designed to reduce high container pressure down to 2 PSI delivery pressure. Ideal for “2-pound” systems or other setups where 2 PSI is the intermediate stage before a final appliance regulator. It handles high flow and is built for safety, ventilation, and durability.

Key Features

• Special twin-stage design for 2 PSI delivery pressure

• Integral relief valve in the 2 PSI (second) stage for over-pressure protection

• Engineered so no more than 5 PSIG will pass downstream if the seat disc is removed

• Large vent (¾″ F.NPT) on the second stage to help prevent blockage and allow vent piping

• Built-in pressure taps on both the 10 PSIG first-stage regulator section and the 2 PSI second stage; plugs removable using a 3⁄16″ hex Allen wrench

• Compact design for easier installation in tight spaces

• Blue finish to clearly designate 2 PSI delivery pressure specification

Specifications

Applications

• Systems requiring a stable 2 PSI delivery pressure (e.g. “2-lb systems”)

• Large propane containers, vapor service, or high flow rate installations

• Where a downstream line pressure regulator will reduce from 2 PSI to burner/appliance pressure

• Commercial and heavy residential propane applications
