Watts 0379082 Valve

The Watts 0379082 (Series 777SI-3/4) is a heavy-duty 3/4" Y-pattern strainer engineered to protect downstream equipment like regulators, pumps, and control valves from pipe scale, rust, and sediment. Designed with a rugged cast iron body and female NPT threaded connections, this wye strainer is built for high-pressure industrial and commercial piping systems. It features a standard 20 mesh 304 stainless steel screen that utilizes a unique flared upstream opening to ensure unrestricted flow and minimal pressure drop. The tapped retainer cap includes a 1/4" closure plug for easy blow-down cleaning without removing the unit from the line.

Rated for non-shock performance, the Watts 777SI handles up to 400 PSI WOG at 210°F and 125 PSI WSP at 353°F. The self-aligning 304 stainless steel flared screen fits securely within the machined seat to prevent bypass of damaging debris. This tapped iron strainer is the industry standard for contractors requiring a 400# class protection solution that simplifies maintenance while maximizing fluid throughput.
