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 A3500V6

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

The REGO A3500V6 Excess Flow Valve is a heavy-duty, flange-mounted safety valve designed for use in propane and LP gas tank systems. Featuring a 3-inch NPT inlet connection, this valve is engineered for high flow capacity with minimal pressure drop, helping reduce pump inlet cavitation during filling and withdrawal operations.This excess flow valve is intended for mounting in flanged tank connections with internal threads and may be used in filling, liquid withdrawal, or vapor equalizing applications. Because there is no direct connection between the external piping and the valve, stresses imposed on piping do not affect valve operation. The valve remains fully enclosed and protected in the event of fire, and is easily accessible for servicing.Key Features & Benefits:Genuine REGO OEM excess flow valve3″ NPT inlet connectionHigh flow capacity / low pressure drop designAutomatically shuts off excess flow conditionsEnclosed, fire-protected flange-mounted constructionDesigned for propane & LP gas serviceTypical

Applications

Bulk propane storage tanksLP gas filling and withdrawal systemsVapor equalization linesIndustrial propane installationsImportant Note:If a riser pipe to the vapor space is used with this valve, the minimum inside diameter of the riser pipe must be at least twice the valve thread size to prevent restriction to the side inlet ports.
