Whitey SS-4VF4 Stainless Steel Needle Valve, 1/4 in. Tube

The Whitey SS-4VF4 is a robust, precision-engineered stainless steel needle valve designed for accurate flow regulation and shut-off in demanding industrial environments. Produced under the Whitey brand by Swagelok, this 2-way valve features an integral bonnet design that enhances durability and prevents leakage, making it ideal for applications in instrumentation, process control, hydraulic systems, and laboratory settings. Constructed from 316 stainless steel, it offers excellent corrosion resistance, suitable for use with a wide range of gases and liquids. Key features include a 1/4-inch tube connection compatible with Swagelok fittings, a Vee-point stem for fine metering, and low-torque operation via an ergonomic black handle. Advantages over competing products include superior pressure handling up to 5000 psig, a broad temperature range from -65°F to 450°F, and reliable sealing performance, reducing maintenance needs and downtime. It excels in high-purity systems and harsh conditions where precision is critical. Potential drawbacks are its premium pricing compared to basic shut-off valves and the need for compatible fittings, but its longevity and accuracy provide significant value in professional setups. This valve is commonly used in chemical processing, oil and gas, and aerospace industries for its reliability and ease of integration.
