Antunes Controls 8103116407 Pressure Switch

The Antunes Controls 8103116407 (Model LGP-G) is a heavy-duty low gas pressure switch engineered for precision monitoring in industrial and commercial burner systems. This manual reset SPDT switch functions as a safety limit, breaking the electrical circuit when gas pressure drops below the calibrated setpoint. It features an adjustable range of 7" to 55" W.C., providing critical protection for high-output systems. The unit utilizes a 1/4" NPT connection for secure integration into gas trains and is housed in a rugged, die-cast aluminum enclosure designed for demanding mechanical rooms. Designed for compatibility with natural gas, propane, and air, this Antunes gas pressure switch ensures reliable field performance and strict compliance with safety shutdown protocols. Technicians value this model for its repeatable accuracy and the tactile manual reset mechanism, which prevents automatic cycling during low-pressure events, ensuring thorough system inspection before resumption of service.

• Precise Pressure Regulation: High-resolution adjustment range of 7-55" Water Column for fine-tuned system protection.
• Manual Reset Safety: SPDT circuitry requires manual intervention after a trip, prioritizing technician oversight and system integrity.
• Durable Construction: Built with a die-cast aluminum housing and a sensitive diaphragm to withstand industrial environments.
• Versatile Media Compatibility: Suitable for use with air, natural gas, and LP gas applications.
• Standard Fitting: Features a 1/4" NPT gas connection for streamlined installation on standard manifolds.

What is the purpose of the manual reset on the LGP-G model?
The manual reset ensures the system cannot restart automatically after a low-pressure drop, requiring a technician to investigate the cause of the pressure loss before manually restoring power to the burner circuit.

Can the Antunes 8103116407 be mounted in any orientation?
For maximum accuracy and to maintain the calibrated setpoint, it is recommended to mount the switch with the diaphragm in a vertical position.

Is this switch compatible with phosphoric acid or corrosive gases?
No, this switch is specifically designed for use with non-corrosive gases like natural gas, propane, and air.
