Product Identity
The Milwaukee Valve 1570 CB2 is a 3-inch flanged cast steel swing check valve designed for inline installation. It uses a single-disc swing mechanism to prevent reverse flow in piping systems. The body and seat are built from cast steel with a chrome-cobalt seal for durability. It operates in horizontal mounting orientation only.
Ideal Applications And Limits
This valve suits industrial pipelines carrying water or steam where a 2 psi cracking pressure and 327 gpm flow capacity match the system design. It handles water pressure up to 285 psi at 100 degrees F and steam pressure up to 200 psi WSP. Buyers needing vertical mounting, a different cracking pressure, or a smaller pipe diameter should look at other models.
Build Integration
The flanged connections bolt directly to mating 3-inch flanges, simplifying inline assembly without welding. Cast steel construction withstands temperatures from -20 to 1,000 degrees F, reducing the need for exotic alloys in high-heat steam service. The chrome-cobalt seat resists wear, extending service intervals in abrasive media.

Questions about this item
What piping and flange rating does the 3 in flanged cast steel swing check valve require?
The valve fits 3 in piping with flange-by-flange connections and is rated for 285 psi water pressure at 100 °F and 200 psi steam pressure.
Can the swing check valve operate in a horizontal line alongside older carbon-steel flanges?
Yes, the valve is designed for horizontal mounting and its cast-steel body mates with standard flanges of the same nominal size and pressure class.
How do I verify the valve is functioning correctly after installation?
Confirm flow in the design direction, listen for the disc closing without chatter, and check that no leakage occurs when upstream pressure drops below the 2 psi cracking pressure.
