MV Series Mini Ball Valve

Publish Time: 2026-07-21 Origin: Site

A compact brass ball valve built for tight installations. Chrome-plated body, quarter-turn operation, rated to 25 bar.

What Makes the MV Series Different

The MV Series Mini Ball Valve solves a common problem: you need a reliable shut-off valve, but the installation space is too small for a standard full-size valve. The MV Series cuts the footprint down without cutting performance.

The valve body is extruded from brass bar stock — not sand-cast. Extrusion produces a denser, more uniform grain structure. The result is higher mechanical strength and better pressure resistance. The chrome plating adds corrosion resistance and a clean finish that holds up in humid and outdoor environments.

The MV Series comes in four port sizes, covering the most common requirements for instrumentation, pneumatic, and plumbing work.

Where the MV Series Is Used

The MV Series fits applications where a full-size ball valve is too bulky. Common use cases:

Instrumentation lines — pressure gauge isolation, flow meter shut-off, panel-mounted valves in control cabinets
Pneumatic systems — compressed air shut-off at FRL units, cylinder supply lines, air preparation equipment
Water and air service lines — capital equipment plumbing, factory design piping requiring complete shut-off
Gas supply lines — natural gas and LPG distribution in residential and light commercial settings
OEM equipment — machinery builders needing compact, reliable shut-off valves in space-constrained assemblies

Note: Ball valves are designed for use in the fully open or fully closed position. Do not use the MV Series for throttling or partial-open flow regulation. Operating in a partially open position can cause cavitation, seat wear, and premature failure.

Frequently Asked Questions

What sizes are available for the MV Series Mini Ball Valve?

The MV Series is available in four sizes: 1/8", 1/4", 3/8", and 1/2". All sizes use standard threaded connections and are in stock for fast shipping.

Can the MV Series valve be used for throttling or flow regulation?

No. The MV Series is designed for full-open or full-close operation only. Using a ball valve in a partially open position for throttling can damage the seat and shorten service life. For flow regulation, choose a needle valve or globe valve instead.

What is the maximum pressure and temperature rating?

The MV Series is rated to 25 bar (360 PSI) and handles temperatures from -10°C to +250°C. This covers most water, gas, and compressed air applications in industrial and commercial settings.

What media are compatible with this brass ball valve?

The chrome-plated brass body is compatible with water, compressed air, natural gas, and non-corrosive fluids. It is not recommended for use with strong acids, alkalis, or seawater. For corrosive media, consider a stainless steel variant. Contact us for media-specific guidance.

Does Reayon Pneumatic offer bulk pricing and OEM customization?

Yes. Reayon Pneumatic offers tiered bulk pricing for orders starting at 500 units. OEM customization includes custom handle colors, private-label packaging, and special thread types. Request a quote through the contact page for project-specific pricing.
