Bitspower G1/4" Mini Valve Black Handle Matte Black BP-MVV-MBKBK

Compact Flow Control

The Bitspower G1/4" Mini Valve integrates directly into a custom liquid-cooling loop to give instant on-off or throttling control over coolant movement. Its quarter-turn handle operates smoothly even in tight routing spaces where a full-size ball valve would not fit. Builders who need to isolate a single component for maintenance without draining the entire system will find the form factor practical. It is not intended for high-pressure industrial plumbing or any application outside PC water-cooling.

G1/4" Thread Compatibility

The valve uses standard G1/4" BSPP threads on both ports, matching the overwhelming majority of water-blocks, radiators, reservoirs and rigid or soft tubing fittings sold for desktop cooling. No adapters are required when every other component in the loop follows the same thread standard. Loops built around non-G1/4" proprietary fittings cannot use this valve without additional conversion parts.

Brass Construction and Seal

The body is machined from brass with a matte black finish and employs a hidden O-ring design that seats the seal inside the bore rather than against the port face. This arrangement reduces the chance of weeping at typical loop pressures while keeping the external profile slim. The valve adds negligible restriction to flow and introduces no audible noise because it contains no moving fluid path other than the rotating ball.
