Swagelok Company SS-DLTW4 Manual Diaphragm Valve

Swagelok SS-DLTW4 is a 1/4 in SS316 high-purity manual diaphragm valve from Swagelok's DL/DS series. Built from stainless steel, it is designed for clean-fluid service in high-purity process lines where diaphragm seals help minimize particulates and provide compatible material for many chemical fluids. End connections are 1/4 in tube socket weld and 1/4 in butt weld, enabling integration with Swagelok tube fittings or welded piping; the body length (A) is 1.75 in (44.4 mm). As a manually actuated valve, it offers straightforward on/off control in challenging environments and supports system cleanliness and traceability when used with Swagelok components. This model is the 1/4 in DL pattern with tube-weld end connections, aligning with high-purity diaphragm valve configurations designed for reliable performance in clean applications. The SS-DLTW4 designation identifies the DL series valve in 1/4 in size, with tube-weld end connections, suitable for incorporation into compact, high-purity fluid systems.
