Frequently Asked Questions

What is a VAL-MATIC air release valve used for?

A VAL-MATIC air release valve automatically vents trapped air from clean water pipelines during system operation. It prevents air pockets that cause flow restrictions, pressure surges, and water hammer, ensuring efficient and reliable performance in municipal water distribution, irrigation, and industrial process systems.

What are the specifications of the VAL-MATIC 15R50-3AT-C6V5Y air release valve?

This VAL-MATIC air release valve is made of cast iron with a 1/2 in FNPT inlet connection. It is designed for clean water applications and operates automatically to release accumulated air. The model number is 15R50-3AT-C6V5Y, and it is suitable for pressures up to 150 psi.

Where to buy a VAL-MATIC air release valve worldwide?

3G Electric supplies the VAL-MATIC 15R50-3AT-C6V5Y air release valve to customers worldwide. As a global industrial sourcing partner, we handle full logistics, customs clearance, and delivery to your site. Contact us for a quote and lead time on this cast iron, 1/2 in FNPT valve.

How to install a VAL-MATIC air release valve?

Install the VAL-MATIC air release valve vertically at high points in the pipeline where air naturally collects. Use thread sealant on the 1/2 in FNPT connection and tighten to manufacturer torque specs. Ensure the valve is accessible for periodic inspection and cleaning of the float mechanism.

Used in

Common applications for VAL-MATIC
Municipal water distribution — VAL-MATIC butterfly valves (e.g., 2003-CD4B5N-L1-1) for isolation and flow control in potable water lines.
Wastewater treatment plants — VAL-MATIC plug valves (e.g., 5801RTL) for sludge and effluent handling with abrasion-resistant Buna-N seals.
Industrial process cooling — VAL-MATIC silent check valves (e.g., 1810A-DSY) to prevent backflow and water hammer in pump discharge lines.
Irrigation systems — VAL-MATIC air release/vacuum valves (e.g., 80C03-2GT-C6B6Y) to maintain pipeline integrity and prevent air locks.
Fire protection systems — VAL-MATIC butterfly valves (e.g., 2006-CD4B5N-L2-1) for sectional control in sprinkler risers, rated to 150 psi.
