Watts 0379113 Strainer
Engineered for high-demand hydronic and plumbing applications, the Watts 0379113 (Series LF777SI) is a 1-inch bronze wye strainer designed to provide essential protection for downstream components like pumps, valves, and chillers. This lead-free wye strainer features a robust cast copper silicon alloy body that meets stringent potable water requirements while ensuring long-term durability in corrosive environments. The integral #20 mesh stainless steel screen effectively captures dirt, rust, and scale, and its special flared upstream opening minimizes pressure drops to maintain optimal system flow. With a 400 PSI WOG rating at 210°F and 125 PSI WSP at 353°F, this FNPT threaded strainer offers the mechanical strength required for both liquid and steam services. The tapped retainer cap, equipped with an NBR gasket and closure plug, allows for easy blowdown maintenance and screen cleaning without removing the unit from the NPT piping system.
Key Benefits for the Contractor:- Lead-Free Reliability: Constructed from lead-free cast copper silicon alloy to ensure compliance with NSF/ANSI 61 and 372 standards for potable water.
- High-Pressure Performance: Rated for 400 PSI non-shock WOG, making it ideal for high-pressure commercial plumbing and HVACR loops.
- Optimized Flow Dynamics: Features a flared screen design that reduces turbulence and ensures unrestricted flow through the strainer.
- Streamlined Maintenance: The tapped retainer cap facilitates quick blowdown connections for purging accumulated debris under pressure.
- Steam Compatible: Capable of handling saturated steam applications up to 125 PSI WSP at elevated temperatures.
What is the standard mesh size provided with this unit?
This model comes standard with a #20 mesh stainless steel screen, which provides a balanced filtration level suitable for most general-purpose sediment and scale removal tasks.
Can this strainer be installed in both horizontal and vertical lines?
Yes, the wye pattern design allows for installation in horizontal or vertical piping. When installing vertically, ensure the flow is downward so that gravity assists in capturing debris within the collection leg.
Does the 0379113 include a blowdown plug?
Yes, the unit is supplied with a solid tapped retainer cap and a closure plug, allowing the technician to either seal the unit or install a blowdown valve for easier maintenance.
