Small brass inline ball valve with round steel handle

Value Brand

Value Brand 1WMN7 1/4" FNPT x MNPT Brass Ball Valve Inline

SKU CH-6PWE-2NF7S

Inline brass ball valve with full-port flow, blowout-proof stem, and PTFE seats rated to 1000 psi CWP

  • Full-port design maximises flow capacity
  • Brass body withstands 1000 psi CWP working pressure
  • PTFE seats handle 300 °F continuous temperature
  • Blowout-proof stem prevents accidental stem ejection
  • Steel round handle enables reliable manual operation

Quarter-turn inline ball valve

This quarter-turn inline ball valve uses a brass body with a chrome-plated brass ball and PTFE seats. It connects a 1/4 inch female NPT thread to a male NPT thread. The full-port design maintains flow without restriction. It suits water, oil, air and steam lines in commercial and residential plumbing.

Check thread type and pressure rating

Verify that the mating fittings use NPT threads rather than BSPT or compression ends. The valve is rated for 1000 psi cold working pressure and 151 psi steam working pressure. Confirm the system temperature stays within the -40 to 300 degrees Fahrenheit range. Ensure the media is compatible with brass and PTFE materials.

Blowout-proof stem and steel handle

A blowout-proof brass stem prevents the stem from ejecting under pressure. The round steel handle provides a firm grip for manual operation. The two-piece body allows straightforward inline servicing. Brass construction resists corrosion in typical plumbing environments.

Questions about this item

Does the valve come with any pipe fittings or thread sealant, or do I need to buy those separately?

The valve is supplied as a single unit with FNPT and MNPT ends already machined; pipe fittings, tape or sealant are not included and must be purchased separately.

Should I choose this 1/4" FNPT x MNPT model or a different connection type for my plumbing job?

Select this model only when the line requires a female NPT inlet and a male NPT outlet in 1/4 inch size; other jobs needing different thread combinations or pipe diameters need a different valve.

What does the 1000 psi CWP rating mean when the valve is installed in a working system?

It indicates the valve can withstand 1000 psi cold water pressure at up to 300 Degrees F, while steam service is limited to 151 psi WSP.
