Antunes Controls 803112701 Pressure Switch

The Antunes Controls 803112701, model RLGP-A, is a precision-engineered low gas pressure switch designed for critical monitoring of gas supply pressures in industrial burner systems and commercial HVAC applications. This SPDT pressure switch features an adjustable set point range of 1" to 6" W.C., providing reliable automatic reset functionality when pressure levels normalize. For field integration, the unit utilizes a 1/4" NPT gas connection and includes a 1/8" NPT vent port. Built to withstand demanding boiler room environments, the 810112701 ensures precise combustion safety by breaking the electrical circuit if the incoming gas pressure drops below the minimum required threshold. Its rugged construction and sensitive diaphragm make it a standard replacement part for maintaining NFPA 86 compliance in fuel-fired equipment manifolds.

• Broad Compatibility: Standard 1/4" NPT bottom connection allows for seamless replacement in most commercial gas trains.
• Reliable Switching: The SPDT contact configuration supports versatile wiring for both alarm signaling and system shutdown.
• NEMA Rated Housing: Durable enclosure protects internal components from dust and debris common in mechanical rooms.
• Fine-Tune Control: The calibrated adjustment dial allows for exact inches water column settings to meet specific appliance requirements.

What is the reset type for the Antunes 803112701?
This model is an automatic reset switch, meaning it will restore the circuit once the sensed pressure rises back above the set point plus the differential.

Can this be used for high gas pressure applications?
No, the RLGP-A series is specifically calibrated as a low gas pressure switch for the 1" to 6" W.C. range. For high-limit protection, a manual reset RHGP series switch is typically required.

Does this switch require a vent line?
Yes, the 1/8" NPT vent port should be piped to a safe outdoor location or fitted with a vent limiter depending on local mechanical codes and proximity to the burner.
