Key Functions of Ductile Iron Air Vent Valve?

1. Air Release: Automatically expels trapped air from the system to prevent air locks and ensure smooth fluid flow.

2. Air Admission: Allows air to enter the system during draining or when the fluid level drops, preventing vacuum formation and potential damage.

3. Pressure Regulation: Helps maintain stable pressure by managing air within the system, reducing the risk of water hammer and other pressure-related issues.

FAQ

Q: How can I identify if my system needs an Ductile Iron Air Vent Valve?

A: To determine if your system needs an air vent valve, consider the following criteria and symptoms:

Criteria for Installation:

Wet Pipe Sprinkler Systems: Requirement: NFPA 13 requires a single air vent on each wet pipe system utilizing metallic pipe.

Methods: Options include manual valves, automatic air vents, remote inspector's test valves, or other approved means.

Location: The air vent should be located at an accessible point near a high point in the system where the greatest volume of trapped air is vented.

Q: How often should I check my Ductile Iron Air Vent Valve?
A: An initial inspection interval of no longer than 12 months is recommended. This ensures that the valve is functioning correctly and any potential issues are identified early.
