A.J. Antunes 803114101 Pressure Switch

The A.J. Antunes 803114101 Pressure Switch, model RLGP-D-2/14, is a precision-engineered low gas pressure switch designed for critical monitoring in commercial and industrial gas-fired systems. This adjustable gas pressure switch features a range of 2-14" W.C. (Water Column), allowing technicians to set exact cut-in or cut-out points for natural gas or LP applications. Built for interoperability with high-demand burners and boilers, the 803114101 utilizes a DPDT (Double Pole Double Throw) contact configuration for flexible wiring of safety shut-off valves and remote alarm circuits. The unit is equipped with a 1/4" NPT process connection and a 1/8" NPT vent port, ensuring straightforward integration into standard gas manifolds. With an auto-reset function and a maximum surge rating of 10 PSI, this OEM A.J. Antunes gas switch provides the reliability required to meet stringent safety codes in mechanical rooms and commercial kitchens.

Key Benefits for Technicians

• Versatile Range: The 2-14" W.C. adjustable setpoint accommodates a wide variety of low-pressure gas monitoring requirements.
• Enhanced Control: DPDT switch configuration allows for simultaneous control of safety limits and auxiliary indicator lights or BMS inputs.
• Rugged Construction: Rated for a maximum pressure of 10 PSI, providing a significant safety margin against line pressure spikes.
• Simplified Installation: Standard 1/4" NPT gas connection and 1/8" NPT venting ensure compatibility with existing piping and atmospheric vent lines.
• Automatic Operation: Auto reset functionality eliminates the need for manual intervention after temporary pressure fluctuations reach safe operating levels.

Common Questions

What is the difference between the RLGP-D and the 803114101?
The 803114101 is the specific part number for the RLGP-D-2/14 model; they are functionally identical and interchangeable.

Can this switch be used for high-pressure sensing?
No, this is specifically a low gas pressure switch designed to trip when pressure drops below the setpoint within the 2-14" W.C. window. For high-pressure cut-outs, an RHGP series switch is typically required.

Does this unit require manual resetting after a trip?
This model features auto-reset logic. Once the gas pressure returns to a level above the setpoint (plus the differential), the contacts will automatically return to their normal operating state.
