A.J. Antunes 803113402 Pressure Switch

The Antunes 803113402 is a heavy-duty RHGP-H high gas pressure switch designed for critical safety monitoring in industrial and commercial combustion systems. This SPDT gas pressure switch operates within a 6-15 PSI range, ensuring precise cutout when line pressure exceeds setpoint limits. Featuring an auto-reset mechanism, this unit is the direct replacement for 803113202, which was a manual reset model that is no longer available. Technicians should note the 1/4" NPT process connection and the 1/8" NPT vent for standard piping integration. The 803113402 is identical to RHGP-H-6/15 and is used extensively in high-output burner manifolds. Its rugged construction provides reliable HVAC pressure switch performance in demanding environments where maintaining specific gas line pressure is vital for system integrity. Always verify electrical loads against the SPDT contact ratings to ensure compatibility with your existing control circuit.

• Precise High-Limit Protection: Effectively monitors for over-pressure conditions to prevent equipment damage.
• Automatic Reset Logic: Streamlines operation by resetting automatically once the gas pressure drops back below the trip point.
• Direct Drop-in Replacement: Seamlessly replaces the discontinued 803113202 manual reset version.
• Standard NPT Ports: Built with a 1/4" NPT inlet and a 1/8" NPT vent for straightforward installation in standard gas trains.
• Durable SPDT Switch: Single-pole, double-throw configuration allows for flexible wiring into various alarm or shutdown circuits.

How do I adjust the pressure setpoint on the RHGP-H-6/15?
The setpoint is adjustable within the 6 to 15 PSI range using the internal adjustment screw located under the protective cover; use a calibrated gauge to verify the trip pressure during commissioning.

Can I use the 803113402 to replace a manual reset 803113202?
Yes, this is the official replacement for the NLA manual reset model, but verify with the site manager that an auto-reset function meets local safety codes for your specific application.

What is the maximum surge pressure for this Antunes gas switch?
While the operating range is 6-15 PSI, the RHGP series is designed to withstand surge pressures, though exceeding the maximum rated pressure of the housing can damage the internal diaphragm.
