Double Female Thread Mini Ball Valve

Compact stainless steel ball valve with threaded end connections. For media shut-off in tight spaces within liquid cooling and water supply/drainage applications. Simple structure with low operating torque.
Nominal pressure PN10
Temperature range -40 ℃ to 120 ℃
Test standard JB/T9092-1999
    Product Description
    The double inner wire mini ball valve is designed for shut-off in space-constrained applications where standard valves cannot fit. Compact, lightweight threaded construction enables quick installation in CDU drain points, rack-level connections, and tight piping configurations. Low flow resistance and low operating torque allow easy manual actuation in confined spaces. PTFE seats and EPDM O-rings provide reliable sealing. Fully degreased for liquid cooling compatibility.
