Antunes Controls 803113401 Pressure Switch

The Antunes Controls 803113401 (Model RHGP-H) is a rugged, industrial-grade high gas pressure switch designed for critical monitoring in industrial combustion systems and commercial burner applications. Operating with a field-adjustable range of 1-7 PSI, this SPDT gas pressure switch ensures system safety by breaking the electrical circuit when gas pressure exceeds the setpoint. Built with a durable die-cast aluminum housing, it is engineered to withstand demanding boiler room environments and high-vibration settings. The auto reset pressure switch functionality allows for seamless operation, automatically restoring the circuit once gas pressure falls back to safe operating levels without requiring manual intervention.

For streamlined installation, the 803113401 features a standard 1/4" NPT gas inlet and a 1/8" NPT vent connection. This OEM-quality component is essential for protecting downstream gas valves and burner components from over-pressure events. Whether you are performing maintenance on a process heater or configuring a new gas train, the RHGP-H 1-7 PSI switch provides the precision and reliability required for UL, FM, and CSA compliant installations.

Key Benefits:

• Precise Pressure Monitoring: Field-adjustable 1-7 PSI range allows for exact setpoint calibration tailored to specific equipment requirements.
• Automatic Reset Logic: Eliminates the need for manual resets, reducing downtime in non-critical safety shutdown scenarios.
• Rugged Housing: Die-cast aluminum construction protects internal SPDT switch components from harsh industrial conditions.
• Standard Connections: 1/4" NPT bottom inlet and 1/8" NPT vent simplify integration into existing gas pressure control manifolds.
• High Surge Tolerance: Designed to handle maximum surge pressures up to 35 PSI, ensuring durability during system fluctuations.

Common Questions:

What is the difference between the HGP-H and the RHGP-H models?
The RHGP-H (like this 803113401) features an auto-reset mechanism, while the standard HGP-H model typically requires a manual reset after a high-pressure trip event.

Does this switch require specific mounting orientations?
While these switches are robust, they are typically designed for horizontal mounting to maintain the factory calibration and ensure the automatic reset functions correctly within the specified pressure range.

Can this be used for both Natural Gas and LP applications?
Yes, the Antunes 803113401 is compatible with natural gas, propane (LP), and air, making it a versatile HVAC high gas pressure switch for various fuel-fired systems.
