Fluid Handling

Pressure-Relief Valves

Pressure-Relief Valves

Protect equipment by opening at a set pressure and closing when the pressure drops; for repeated use

Breather Vents

Maintain even pressure and vacuum as temperatures change by allowing airflow in tanks and enclosures

Pressure-Relief Discs

Pressure-Relief Discs

Rupture at a set pressure or temperature to vent fluid and gas and protect machinery; one-time use

Air Vent Valves

Air Vent Valves

Eliminate air pockets from fluid lines to maintain consistent flow and prevent surges

Vacuum Breakers

Vacuum Breakers

When pressure drops, vents open to prevent suction from drawing liquid back upstream

Electrical

Electrical Enclosure Vents

Electrical Enclosure Vents

Attach to sealed enclosures so air can flow to equalize temperature and pressure

Electrical Enclosure Drain Vents

Electrical Enclosure Drain Vents

Prevent moisture from getting trapped inside enclosures while letting air flow through

Electrical Enclosure Drains

Electrical Enclosure Drains

Release moisture to keep components dry

Containers, Storage, and Furniture

Drum Vents

Prevent drum failure by releasing pressure and vacuum buildup

Facility and Grounds Maintenance

Air Admittance Valves

Air Admittance Valves

Allow air into drain, waste, and vent systems so you don't have to vent plumbing to the outdoors
