The air release valve is designed for wet pipe sprinkler systems and the casing of horizontal split-case fire pumps. It automatically vents small pockets of accumulated air while the system operates under pressure above atmospheric levels. This helps maintain system efficiency, reduces the risk of air binding, and ensures smooth operation.
Key Features:
- Automatically vents trapped air during pressurized system operation
- Enhances system efficiency and prevents air-related disruptions
- Ideal for use in sprinkler systems and fire pump casings
- Small orifice design – vents air only, no water discharge
