How to Size a Maxitrol RV Series Poppet Gas Regulator
When sizing a poppet regulator, you need to know the following factors:
- Gas Type
- Available Inlet Pressure
- Desired Outlet Pressure
- Zero Governor Application (indicated by model number ending in “Z”)
- Will the regulator control the main burner and pilot load OR the main burner only?
- Required minimum and maximum flow rate in cfh or m3/h or Btu/h
- Pipe Size
In most cases, the manifold pipe size has already been selected on the basis of good engineering practice, and the regulator pipe size should conform to this size.
Sizing Example for Rubber Seat Poppet Gas Regulators
Known: Single 150,000 Btu/h main burner; pipe size 1/2”; inlet pressure 7” w.c.; outlet pressure 4” w.c.
Solution: The RV48 (1/2”) has a maximum capacity of 230,000 Bth/h and a maximum individual load of 160,000 Btu/h. The pressure drop at a flow rate of 150,000 Btu/h is 0.4” w.c., well below the available differential of 3” w.c. The RV48 (without “L” fixed orifice) is the correct regulator to use for the application.
Installation and Maintenance
Maxitrol RV series poppet regulators have the advantage of being able to be mounted in several positions, except for those bearing the suffix “D”. However, it is important to note that positions other than vertical may result in minor variations in outlet pressure. Models bearing the “D” suffix, as well as those fitted with a ball vent limiting device, must be mounted in the vertical position to ensure correct operation and compliance with safety standards. This consideration is essential for optimum performance of your Maxitrol gas regulator.
However, it is important to mention that installing the Maxitrol RV Series poppet regulators requires adherence to stringent safety standards. As per the manufacturer’s guidelines, service and installation must be conducted by trained, experienced technicians, ensuring compliance with all applicable OEM instructions and government codes, including plumbing, mechanical, and electrical regulations. Maxitrol emphasizes the importance of installing and operating their products strictly according to their safety warning instructions.
Regular maintenance, including periodic inspections for wear, particularly of the rubber seat, and keeping the regulator clean and free from debris, is crucial. This diligent approach not only extends the lifespan of the regulator but also ensures its safe and efficient operation.
In Summary
