Swagelok SS-16DKM4-F4-1, Needle Valve with Rupture Disc, 1/4 in. Male NPT-to-Female NPT, 1900 psig Burst Disk, 316L Stainless Steel

This Swagelok® Integral-Bonnet, Nonrotating-Stem Needle Valve with integrated Rupture Disc has a 1/4" male NPT inlet and 1/4" Female NPT outlet and is rated for 1900 psig (+/- 100 psig at 22°C / 72°F).

The valve has a soft-seat stem and PCTFE stem tip which limits its' maximum working temperature to 93°C (200°F). The valve has a maximum flow coefficient of 0.09Cv and can withstand pressures significantly higher than the rupture disc (up to 6000 psig at 37°C / 100°F).

This straight pattern valve/rupture disc combination, made of 316L stainless steel is compact and convenient for sample cylinder use and anywhere where space is at a premium.

The rupture disc can be replaced easily without removing the valve or tee from the system. Rupture disc replacements are available with a nominal burst pressure of either 1900 or 2850 psig.

Caution: Compressed gas cylinders must be equipped with pressure relief devices in accordance with CGA S-1.1, the definitive standard for the selection of the correct pressure relief device required to meet the requirements of the U.S. DOT in 49 CFR for over 150 gases.

Be sure to use the correct pressure-relief device for the gas being used.
Proper filling of cylinders according to DOT specifications, or other local regulations, is critical in preventing overpressurization.
