Regulates gas pressure within a connected fuel supply system by reducing incoming pressure and controlling the gas passage toward downstream in HVAC systems. The Itron-Actaris B42R-1 Gas Regulator uses an internal regulating mechanism that responds to pressure changes and adjusts the passage to maintain the required outlet condition. Its 1" connect to the physical interface with the gas piping, while the 6-16" WC range defines the pressure range controlled by the regulator. The 1/2" X 9/16" orifice forms the internal opening through which gas passes during regulation. It is used in gas-fired equipment where controlled pressure and gas flow are required for proper operation.

Pressure Reduction:
Reduces the incoming gas pressure to the controlled pressure required by the connected equipment. The regulator’s internal mechanism responds to pressure changes and adjusts the gas passage to maintain the designated outlet pressure range. This regulated pressure supports a consistent gas supply through the downstream system while keeping the pressure relationship within the specified operating range.

Gas Flow Control:
Controls the movement of gas through the regulator by adjusting the available internal flow passage. The regulating mechanism responds to downstream demand and maintains the required gas flow relationship between the inlet and outlet sides. This controlled passage supports consistent gas delivery to the connected equipment throughout normal operating conditions.

Replacement Guidelines:
Replacement of the Itron-Actaris B42R-1 1" Gas Regulator 6-16" WC 1/2" X 9/16" Orifice requires matching the regulator’s connection size, pressure range, orifice configuration, gas-flow requirements, equipment specifications, and piping arrangement. The replacement should also suit the existing gas supply system and designated operating conditions.

Common Failure Symptoms:

  • Inconsistent outlet pressure.
  • Irregular gas flow.
  • Unstable regulator response.
  • Delayed pressure adjustment.
  • Variable downstream pressure.
  • Inconsistent flow regulation.
  • Irregular operating response.
  • Unstable gas-supply conditions.

Equipment Compatibility:
The Itron-Actaris B42R-1 Gas Regulator is intended for compatible gas-fired equipment requiring the corresponding regulator configuration. Verify the equipment model, connection arrangement, pressure requirements, orifice configuration, and manufacturer’s documentation before purchasing.

Product Questions (7)
Customer Questions
What maintenance is required for the Itron-Actaris B42R-1 Gas Regulator?

Regularly inspect the regulator for leaks, corrosion, and debris. Clean the inlet and outlet ports, and check that the internal relief valve operates smoothly. Always shut off gas supply before servicing. Routine maintenance ensures accurate pressure control and prevents unsafe gas flow.

What are common issues with the Itron-Actaris B42R-1 Gas Regulator?

  • Inconsistent outlet gas pressure.
  • Regulator failing to maintain proper pressure control.
  • Gas flow restriction or reduced output.
  • Internal diaphragm wear affecting regulation.
  • Debris buildup causing unstable performance.

What role does the B42R-1 perform in the connected gas circuit?

The B42R-1 functions as the regulating component that manages gas pressure and controlled movement through the connected pathway.

How does pressure variation affect regulator operation?

Changes in pressure act on the regulating mechanism, producing an adjustment that maintains the required pressure relationship through the assembly.

How does the regulator control gas movement between its inlet and outlet?

The regulating mechanism varies the available internal passage, controlling gas movement between the inlet and outlet sides.

How does the regulator maintain the designated downstream pressure?

Its internal regulating mechanism responds to pressure changes and adjusts the gas passage to maintain the designated downstream pressure.

What path does gas follow through the regulator assembly?

Gas follows the internal passage from the inlet toward the outlet while the regulating mechanism manages the available flow path.

Installation Steps

Step1: Turn off the gas supply and ensure all downstream appliances are off.

Step2: Remove the old regulator and disconnect gas lines.

Step3: Install the new regulator in correct flow direction, tightening fittings securely.

Step4: Check vent orientation and reconnect gas piping per code.

Step5: Pressurize system, check for leaks, then restore gas and test regulator function.
