Watts 0220081 Strainer
The Watts 0220081, specifically the 77SI-2 2-inch cast iron strainer, is a heavy-duty wye-pattern solution designed to protect sensitive downstream equipment from scale, rust, and pipe debris. Engineered with a rugged cast iron body and NPT threaded connections, this 2" Y-strainer is built for high-demand hydronic and steam applications. It features a precision-machined seat that ensures the stainless steel 20 mesh screen remains self-aligning for a leak-proof fit. Rated for 400 PSI at 150°F (WOG) and 250 PSI at 406°F (WSP), this commercial inline strainer provides dependable filtration in non-potable water, oil, and gas systems. The tapped retainer cap includes a blow-down connection, facilitating easy sediment removal without full disassembly. For contractors managing steam lines or chemical processing piping, the Watts 77SI series offers the mechanical durability required to prevent valve fouling and pump damage in industrial environments.
Key Benefits- Self-Aligning Screen: A machined seat ensures the 304 stainless steel screen is perfectly positioned every time the cap is closed.
- High-Pressure Rating: Robust construction supports up to 400 PSI WOG, making it suitable for demanding industrial fluid filtration.
- Maintenance Accessibility: The 3/4" tapped blow-down outlet allows for flushing sediment without taking the system offline.
- Durable Material: Reinforced cast iron body provides superior resistance to thermal expansion in high-temperature steam services up to 406°F.
- Standardized Fit: 2-inch FNPT ports allow for seamless integration into existing 2" iron pipe schedules.
What is the maximum pressure rating for steam applications?
This unit is rated for a Maximum Working Steam Pressure (WSP) of 250 PSI at 406°F. For liquid or gas service (WOG), it supports up to 400 PSI at 150°F.
Is this strainer lead-free for potable water systems?
No, the 77SI model 0220081 is a standard cast iron unit intended for non-potable applications such as steam, heating hot water, and chilled water loops. It does not meet the low-lead requirements of the Safe Drinking Water Act.
Can I install a blow-down valve on this strainer?
Yes, the retainer cap is tapped for a 3/4" NPT connection, allowing for the installation of a ball valve to perform strainer blow-down cleaning while the system remains pressurized.
