Maxitrol M511B-3/4 3/4 Inch Modulating Gas Valve with Vent Tap

The Maxitrol M511B-3/4 Selectra Modulating Valve is a 3/4 inch gas valve with vent taps on both sides, designed to deliver precise temperature control for industrial heating applications. As the heart of the Selectra Electronic Gas Flame Modulating System, this valve provides precise, non-fluctuating, instantaneous temperature control without requiring a motor or mechanically driven butterfly valve.

Key Features:

• Designed exclusively for negative pressure (pull through) applications
• Counter spring keeps the valve in the closed position despite the downward pull of negative pressure
• Set for applications up to 1.5 inch w.c. and is not adjustable
• 3/4 inch inlet and outlet size, 0.5A current draw, compatible with Series 14, 24, 44, 94, SC11, and DFM controllers
• Operating temperature range of -40°F to 125°F
• Maximum inlet pressure of 1/2 psi, CSA Listed
• Suitable for natural, manufactured, mixed, liquefied petroleum, and liquefied petroleum gas-air mixtures
• Vent taps on both sides for convenient pressure testing and system monitoring

A separate upstream pressure regulator is required for the M511 valve. This modulating valve is ideal for applications requiring stabilized area heating, consistent baking or drying temperatures, elevated heating, and various industrial process applications where maintaining precise, consistent temperatures is critical.
