Swagelok SS-44F4 Stainless Steel Ball Valve One Quarter Inch NPT

Swagelok SS-44F4 is a stainless steel, one-piece 40 Series ball valve designed for precise on/off control in compact two-way straight-pattern installations. It features 1/4 in. FNPT end connections and a Cv of 3.0, providing predictable flow and reliable shutoff in instrumentation and process lines. The valve's body and components are made from 316 stainless steel, delivering corrosion resistance for gas or liquid services in laboratory and analytical systems. The single-piece construction, part of Swagelok's 40 Series, supports robust performance in tight spaces while maintaining leak-tight operation when paired with Swagelok tube fittings. This valve is intended for applications where compact footprint, dependable isolation, and a straightforward two-port configuration are required, such as process sampling lines and instrument manifolds. End-to-end compatibility with Swagelok fittings ensures consistent connection integrity, and the 1/4" size makes it a common choice for instrumentation panels and small-diameter lines.
