Maxitrol RV111-2 1/2 Gas Pressure Regulator 2-1/2 Inch NPT 17 Million BTU

The Maxitrol RV111-2 1/2 is a 2-1/2 inch NPT straight-thru-flow gas pressure regulator designed for high-capacity commercial and industrial gas-fired appliances. This non-lockup regulator features Maxitrol's cone principal design that allows gas to flow straight through without changing directions, reducing frictional resistance and providing greater capacity with accurate, sensitive regulation at low pressure differentials.

Key Features:

• 2-1/2 inch NPT threaded connections for straight-thru-flow design
• 17,000,000 BTU capacity rating for high-demand applications
• Maximum inlet pressure: 1 PSI
• Outlet pressure range: 3-6 inches water column (adjustable)
• Includes 3-6 inch WC spring (compatible with R11110 spring)
• Brass construction with Buna-N diaphragm
• CSA design certified for 1/2 PSI rated pressure under ANSI standards
• CSA listed for compliance with national safety and performance standards

Application Notes:

• Main burner only, non-lockup type regulator
• Designed for single appliance applications
• Should not be used as line gas pressure regulator ahead of low pressure controls
• Use only where downstream controls can operate at line pressure
• Recommended for horizontal mounting position only
• Suitable for natural gas and manufactured gases

This regulator is ideal for residential, commercial, and industrial gas-fired equipment used on low or medium pressure gas supplies. The straight-thru-flow design offers a definite advantage for handling large capacity appliances with limited supply pressure. Professional installation by a licensed gas fitter is required.
