Product Description

The VAL-MATIC Air Release/Air Vacuum Valve: Clean Water is a combination vacuum and air release valve in cast iron with a 3-inch FNPT inlet connection (MPN 20C03-6CT-C6B5Y). It is designed to exhaust and admit air in clean-water systems, supporting efficient pipeline operation.

Frequently Asked Questions

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

A VAL-MATIC combination air release/air vacuum valve is used in clean water pipelines to automatically exhaust large volumes of air during system filling and admit air during draining, while also releasing accumulated air under pressure. This prevents vacuum collapse, reduces surge damage, and improves system efficiency in municipal water, irrigation, and industrial applications.

What are the specifications of the VAL-MATIC 20C03-6CT-C6B5Y valve?

The VAL-MATIC 20C03-6CT-C6B5Y is a cast iron combination vacuum and air release valve with a 3-inch FNPT inlet connection. It is designed for clean water service and manufactured by VAL-MATIC. The valve body is cast iron, and the inlet connection size is 3 inches, making it suitable for medium-to-large pipeline systems.

Where to buy VAL-MATIC air release valves worldwide?

VAL-MATIC air release valves are available to order through 3G Electric, a global industrial equipment distributor. We source and deliver this valve worldwide, handling full logistics, customs clearance, and delivery to your site. Contact 3G Electric for pricing and lead time on the VAL-MATIC 20C03-6CT-C6B5Y or other models.

How to install a VAL-MATIC combination air valve?

Install the VAL-MATIC combination air valve vertically with the inlet connection at the lowest point, typically on a tee or flange at high points in the pipeline. Ensure the valve is clean and free of debris before installation. Use appropriate thread sealant on the FNPT connection and support the valve weight. Follow standard pipeline practices for isolation and testing.

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.
