- Nickel-plated brass body resists corrosion in air, steam and water lines
- 250 psi operating pressure handles demanding pneumatic and hydraulic circuits

- Chrome-plated brass ball with standard port ensures smooth two-way flow control
Quarter-Inch Brass Mini Ball Valve
The Zoro Select G-MVSP-25M is a manual two-way valve built from nickel-plated brass with a chrome-plated brass ball. It suits technicians and maintenance teams needing inline shut-off for air, steam, or water lines in workshop or light industrial settings. The straight body style and standard port keep flow paths simple for basic fluid control tasks. It is not suited for combustible gas service or applications requiring 3-A sanitary compliance.
Install With Standard Pipe Threads
The valve connects via 1/4 inch FNPT by MNPT threads, fitting directly into existing piping without special tools or adapters. Two-piece construction allows straightforward assembly, though the body cannot be serviced in-line once installed. Over-tightening the threads risks damaging the brass seats, so hand-tighten plus one turn is typical practice. No electrical wiring or actuation setup is required for this manual handle design.
Rated For 250 PSI Air And 150 PSI Steam
Operating pressure reaches 250 psi for air and water, while steam service is limited to 150 psi. Vacuum capability extends to 29.9 in Hg for evacuation tasks. These limits cover most shop air compressors and low-pressure steam circuits. The valve will not handle combustible gas duties or high-pressure hydraulic systems beyond the stated ratings.

Questions about this item
How can I verify the Zoro Select G-MVSP-25M mini ball valve is operating correctly after installation?
Turn the handle through its full quarter-turn travel and feel for smooth, positive stops; then apply system pressure up to 250 psi for air or water and 150 psi for steam, checking all joints for leaks.
What comes with the Zoro Select G-MVSP-25M valve and what additional fittings must I supply?
The valve itself is supplied with 1/4 inch FNPT x MNPT threads; you must provide compatible pipe nipples, thread sealant or tape, and any adapters required for your piping layout.
Which pressure-rated version of the Zoro Select G-MVSP-25M should I select for my application?
Choose this model when your system runs at or below 250 psi for air or water, 150 psi for steam, or requires vacuum service down to 29.9 in Hg; all ratings are covered by the same nickel-plated brass body.
