Maxitrol RV53-3/4 Regulator

When you're outfitting a high-capacity system, the Maxitrol RV53-3/4 remains the industry standard for appliance gas regulators. Featuring a straight-thru flow design, this 3/4" NPT unit utilizes a precise conical valve to minimize frictional resistance, delivering superior performance at low inlet pressures. Rated for a maximum inlet pressure of 1/2 PSI, it effectively manages natural gas and LP gas applications with a factory-set outlet pressure range of 3-6" w.c.

For a veteran contractor, the multi-positional mounting capability of the aluminum housing provides the necessary flexibility for tight mechanical rooms or specific equipment orientations. This non-lockup regulator is engineered for a maximum capacity of 1,300,000 BTU/hr, providing stable pressure for residential and commercial gas-fired appliances. The improved flow pattern ensures sensitive regulation even at low pressure differentials, preventing common pilot or burner fluctuation issues on the job site.

• Straight-Thru Flow Design: Conical valve geometry allows gas to pass without changing direction, maximizing capacity and minimizing drop.
• Superior Heat Tolerance: Reliable operation in ambient temperatures ranging from -40° to 205° F.
• Versatile Fuel Compatibility: Fully certified for use with natural, manufactured, and mixed gases, as well as liquefied petroleum (LP).
• Heavy-Duty Construction: High-strength pressure cast aluminum housing ensures structural integrity in demanding environments.

Common Questions

Can I use the RV53 as a line pressure regulator?
No, this is a main burner appliance regulator. It should only be used where the downstream controls are rated to handle the potential line pressure, as it is a non-lockup type.

Is this regulator suitable for outdoor installation?
Yes, the Maxitrol RV53-3/4 is designed for multi-positional mounting and wide temperature ranges, though it should be protected from direct water ingress or ice accumulation.

What is the lockup capability of this model?
The RV series consists of non-lockup regulators. For applications requiring positive shut-off at zero flow, a dedicated lockup-style regulator must be selected.
