Questions about this product?

The ATP 177-300 inline control valve provides air-to-open operation in a normally closed, 3-inch grooved configuration. It is intended for gravity-dump water distribution, particularly spreader-bar installations where the valve controls water entering the bar.

Its aluminum body and grooved connections suit a matching inline plumbing arrangement. A 1/4-inch air hose fitting is required and is not included. This valve is not recommended for spray-head use. Match the valve to the job rather than selecting it by pipe size alone.

Feature Benefit
Normally closed, air-to-open operation Use an air control circuit to open the valve when discharge is needed.
