Antunes Controls 804114202 Pressure Switch

The Antunes Controls 804114202 Pressure Switch (Model HLGP-D) is a precision-engineered dual gas pressure switch designed to provide comprehensive single-point monitoring for both high and low gas pressure conditions. This manual reset pressure switch is essential for maintaining safety in industrial combustion systems, commercial boilers, and large-scale gas-fired equipment. Featuring a high gas pressure range of 10-50" W.C. and a low gas pressure range of 2-14" W.C., this robust unit ensures your system stays within critical operating parameters. The HLGP-D 804114202 utilizes 2-DPDT (Double-Pole Double-Throw) switching technology, enabling the control of two independent circuits per setpoint for superior redundancy and complex system integration. Built with a rugged die-cast aluminum housing, it withstands harsh environments with an ambient temperature range of -40°F to 140°F. Installation is streamlined via 1/8" NPT connections for both the gas inlet and vent, making it a versatile choice for professional HVACR technicians seeking reliable safety interlocks.

• Enhanced Safety: The manual reset mechanism ensures a technician must inspect the system before restarting after a pressure fault.
• Industrial Durability: Features a rugged die-cast aluminum enclosure and magnetic reed switch technology for long-term reliability.
• Versatile Circuitry: The 2-DPDT configuration allows for simultaneous control of safety shut-off valves and remote alarm signals.
• Precise Control: Wide adjustable setpoints (10-50" W.C. High / 2-14" W.C. Low) accommodate a variety of gas-fired appliance requirements.

Common Questions About the Antunes 804114202:

How do I reset the Antunes HLGP-D after a trip?
When pressure exceeds the high setting or falls below the low setting, the switch latches in the off position. Once the pressure returns to the safe operating range, you must manually depress the reset button on the housing to restore the electrical circuit.

What are the electrical ratings for this gas pressure switch?
The Model HLGP-D is rated for 10A at 125 VAC and 5A at 250 VAC. It also supports pilot duty at 125 VA for 125-250 VAC, making it suitable for most industrial control panels.

Does this switch require a specific mounting orientation?
Yes, for optimal accuracy and performance, Antunes recommends mounting the switch in a horizontal position with the inlet stem pointing downward. While it does not require perfectly precise leveling, a horizontal orientation is standard for proper operation.
