Antunes Controls 8101111202 Pressure Switch

As a field-tested solution for industrial combustion systems, the Antunes Controls 8101111202 (Model HGP-G) is a high gas pressure switch engineered to provide critical safety interlocking for gas-fired equipment. This manual reset SPDT pressure switch features an adjustable set point range of 2-20" W.C., making it a staple for technicians managing boilers, commercial ovens, and process burners. Designed to break the electrical control circuit when gas pressure rises above the desired threshold, the unit requires a deliberate physical reset once the pressure returns to safe operating levels, ensuring the operator can investigate the root cause of the pressure spike.

The 8101111202 is built with a rugged die-cast aluminum base and a 1/4" NPT bottom inlet for secure integration into existing gas trains. With an ambient operating temperature rating from -40°F to 140°F and a maximum surge pressure of 15 PSI, this Antunes gas pressure switch is suitable for demanding environments where precision and durability are non-negotiable. Its compact, ventless design and SPDT switch configuration allow for flexible wiring into various safety limit strings and alarm circuits.

Key Benefits

• Safety Compliance: The manual reset mechanism prevents automatic equipment restarts, meeting strict industrial safety protocols for high-pressure events.
• Versatile Range: Field-adjustable 2-20" water column set point range allows for precise tuning across multiple burner types.
• Simplified Installation: Standard 1/4" NPT connection and a compact footprint ensure seamless replacement for existing Model G units.
• Rugged Reliability: Durable aluminum construction and high-quality internal components withstand the rigors of commercial mechanical rooms.

Common Questions

What is the difference between this HGP-G model and an auto-reset version?
The HGP-G (High Gas Pressure - Gas) requires a manual reset by a technician after a trip occurs, whereas auto-reset models automatically re-close the circuit when pressure drops. High gas safety standards frequently mandate manual reset switches to ensure a thorough system check after an over-pressure condition.

Can this switch be mounted in any orientation?
While these switches are robust, they should be mounted in a horizontal or vertical position as reasonably level as possible for the most accurate set point performance. Always perform a soap bubble leak test on the NPT inlet after installation.

Is this switch suitable for outdoor use?
The unit is rated for ambient temperatures down to -40°F, but if installed outdoors, it should be protected from direct weather elements or housed in a NEMA-rated enclosure to prevent moisture ingress into the electrical housing.
