Bermad IR-1-C10-P-S-NP-T Combination Air Valve 1 Inch

Product Description

The BERMAD IR-1-C10-P-S-NP-T is a combination air valve designed for use in pressurized pipeline systems. It serves the dual function of releasing large volumes of air during system fill and startup, and continuously venting small air pockets during normal operation. The valve also allows air ingress during system drain or vacuum conditions, protecting the pipeline from negative pressure damage. A built-in test point provides the ability to check operating conditions without taking the system offline. Licensed plumbers and water system technicians are the primary installers of this type of valve.

This combination air valve is suited for residential and commercial water supply, irrigation, and hydronic piping systems where air management is critical to system efficiency and pipe integrity. The 1-inch end connection accommodates standard pipeline configurations in both new construction and retrofit installations. It is typically installed at high points in a pipeline where air naturally accumulates.

Key Features

• Combination air valve handles both large-orifice air release and small-orifice continuous venting in a single body
• Integrated test point allows pressure and performance checks without system shutdown
• 1-inch connection size fits standard pipe configurations in water and irrigation systems
• Designed to prevent vacuum formation and negative pressure damage during system drain-down
• Compact single-unit design reduces installation points and simplifies system maintenance

Compatibility

Designed as an OEM-style replacement or new-installation combination air valve for pressurized water supply, irrigation, and hydronic pipeline systems requiring air and vacuum relief at a 1-inch connection.

Installation Notes

Installation should be performed by a licensed plumber or qualified pipefitter in accordance with applicable IPC and local plumbing codes. Shut off and depressurize the pipeline fully before installing or servicing the valve. The valve must be mounted vertically with the float chamber oriented upright to ensure proper operation. Use the integrated test point only after verifying that all downstream isolation procedures are in place.
