Bronze inline check valve with sweat connections

Milwaukee Valve

Milwaukee Valve UP1509 1/2" Sweat Bronze Spring Check Valve

SKU CH-SG7X-9Z0F7

Bronze inline swing check valve with sweat connections handles 10 gpm water flow at up to 300 psi and 200 °F

  • TypeOther
  • Bronze construction resists corrosion for long service life
  • Spring-loaded check mechanism prevents backflow automatically
  • Sweat connections enable secure copper pipe installation
  • Rated for 300 psi at 150 °F water pressure
  • Operates from -20 °F to 200 °F temperature range

1/2-Inch Bronze Spring Check Valve

This inline swing check valve fits 1/2-inch copper tubing with sweat connections on both ends. The low-lead bronze body and brass seat handle water up to 200 degrees Fahrenheit and 300 psi at 150 degrees Fahrenheit. It is built for horizontal mounting in residential or light-commercial plumbing systems.

Low Cracking Pressure and Sweat Ends

A cracking pressure between .750 and 1.000 psi lets the valve open with minimal flow resistance. Sweat-by-sweat ends mean the installer solders directly to copper pipe, creating a permanent leak-free joint without threaded adapters. The bronze seal and brass seat resist corrosion in potable water applications.

Horizontal-Only Bronze Construction

The valve must be installed horizontally; vertical orientation is not supported by the design. Bronze body and seat materials withstand temperatures down to -20 degrees Fahrenheit, so the unit survives seasonal shutdowns in unheated spaces. Rated for 10 gallons per minute, it suits standard bathroom fixture supply lines.

Questions about this item

Will the bronze seat or brass seat need replacement after years of 10 gpm flow?

The valve uses a bronze body with a brass seat rated for 300 psi at 150 °F, so the sealing surface is integral to the design and not a separate replaceable cartridge.

What pressure or temperature limit will be reached first during continuous hot-water circulation?

The maximum water pressure is 300 psi at 150 °F and the maximum temperature is 200 °F, so the pressure ceiling is encountered before the temperature ceiling in typical recirculation loops.

How much heat does the valve add to the line when it runs all day at 10 gpm?

The bronze body and brass seat conduct heat from the fluid, but the valve itself generates no additional heat; it simply passes the water temperature up to the 200 °F rating.
