VAL-MATIC 15A.3 Air Release Valve FNPT 1 x 1/2 Cast iron

Val-Matic air release valve is designed to ensure that any entrained air in the water system is automatically released to provide superior system performance. This air release valve is used in water treatment plants, sewage systems, industrial processes and irrigation systems, ensuring the smooth and efficient operation of fluid transport and distribution systems.

Working Mechanism:

• Mount the Val-Matic air release valve at the highest points in a pipeline where air collects easily.
• As air bubbles penetrate the valve and replace the liquid inside, the liquid level decreases.
• When the level falls to where it no longer buoys the float, the float drops. This motion pulls the seat away from the orifice, activating the valve to open and vent the collected air into the atmosphere.
• As the air is released, liquid re-enters the valve, once again buoying the float, raising it until the seat pushes against the orifice, shutting the valve.
• This cycle automatically repeats as often as required to sustain an air-free system.

Features:

• This Val-Matic 15A.3 air release valve features cast iron construction for ensuring durability and robustness in fluid system applications.
• It features 316 stainless steel float material, excellent corrosion resistance and reliability.
• This Val-Matic 15A.3 air release valve has a non-clogging design that removes backwash.

Standards and Approvals:

• NSF 372
• NSF 61
• ISO

Frequently Asked Questions:

Q. What is the difference between air relief valves and air release valves?

A. An air release valve is open at atmospheric pressure then closes automatically when liquid is present. A relief valve won't release collected air at pressures below the set point.

Q. Where do you install air release valves?

A. Air release valves and air vacuum valves are typically installed at every 800 m on long pipe to easily release and draw air into the system.

Q. How do I maintain this Val-Matic 15A.3 air release valve?

A.

• Regularly inspect the valve for visible issues or damage.
• Keep the valve clean by removing debris and foreign particles.
• Lubricate moving parts and threads as recommended to prevent rust.
• Check for leaks around the valve body, connections and outlet.
• Test the valve's operation by manually triggering air release.
• Adjust the valve's operating pressure within the specified range if necessary.
• Maintain documentation of maintenance activities and inspections.
• Consider environmental conditions when operating the valve.
• Develop an emergency response plan for valve failures.

Q. What type of connections does this Val-Matic air release valve have?

A. It features FNPT connections for easy installation.

Q. What are the factors to consider while choosing an air release valve?

A. Major factors include fluid compatibility, inlet / outlet size, operating pressure range, venting capacity and material construction.
