Cryogenic needle valves: from a successful cooperation to a wide range of products

Sami Instruments offers a wide range of valves and accessories, with standard temperature – as per our recent post – up to -46°C (-50°F), but we can also supply valves and fittings for cryogenic applications, up to -196°C (-320°F).

This cryogenic valve range was developped in 2014 thanks to the cooperation with WIKA Italy: the customer was interested in an alternative to the current supplier. Sami was eager to take this occasion to widen its medium and high pressure range including the cryogenic version.

The solution and relevant offer was accepted and the customer has been purchasing these valves from Sami ever since (approx. 300 pcs. until today).

The models involved in this cooperation were only two (15.000 psi needle valve 1/4″ and 1/2″ NPT connections), but Sami is able to supply a wide range of configurations of cryogenic needle valves.

The valves were installed in a Liquid Natural Gas (LNG) processing plant.
