Frequently Asked Questions

What is the VAL-MATIC 15R75-3AT-C6V5Y air release valve used for?

The VAL-MATIC 15R75-3AT-C6V5Y air release valve is used in clean water systems to automatically release trapped air from pipelines. This prevents air pockets that can cause flow restrictions, pressure surges, and water hammer. It is commonly installed at high points in municipal water distribution, irrigation, and industrial water supply networks.

What are the specifications of the VAL-MATIC 15R75-3AT-C6V5Y air release valve?

This VAL-MATIC air release valve has a 3/4 inch FNPT inlet connection and a cast iron body. It is designed for clean water applications. The manufacturer part number is 15R75-3AT-C6V5Y. The valve automatically vents accumulated air from pressurized pipelines to maintain system efficiency and protect against pressure transients.

Where to buy the VAL-MATIC 15R75-3AT-C6V5Y air release valve worldwide?

You can source the VAL-MATIC 15R75-3AT-C6V5Y air release valve through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time. We supply genuine VAL-MATIC components for clean water systems.

How to install a VAL-MATIC air release valve?

Install the VAL-MATIC air release valve at the highest point of the pipeline where air naturally collects. Use a full-port isolation valve upstream for maintenance. Ensure the valve is oriented vertically with the inlet connection facing down. Apply thread sealant to the FNPT connection and tighten to manufacturer torque specifications. Test for leaks after pressurization.
