The Cryo Star Floating & Cryo Star Trunnion Starline Ball Valves are used in Cryogenic services across the world and consists of 2 and 3 Piece bolted body constructions with screwed, welded and flange connection availability. Sizes are available from 1/4”-8” for Full Bore Ball Valves and 3/4”-10” for Reduced Bore with pressures up to Class 2500LB (6000PSI/PN420).

The Cryo Star Starline Ball Valve provides a quality solution for extreme environment applications for all types of Cryogens. These include Oxygen, Methane, Nitrogen, Hydrogen, Ammonia, Flourine, LNG and Deuterium. The complete range of Cryo Star Ball Valves have been designed and tested to the highest of industry standards bringing superior technical knowledge and design together with world leading manufacturing facilities.

Manual and automatic control though pneumatic or electric solutions offer reliable operation for remote or inaccessible locations with added safety fail safe available.

Key design features incorporated into the Cryostar include an anti-blowout shaft, sprung energised seats and single piece solid extended bonnet. Stem extensions comply to all relevant industry standards and position stem and stem packing away from harmful media applications , prevent seal freeze up and keep operational torques low.

It is generally accepted that Cryogenic temperatures ranges begin at -150°C in Oil and Gas industries and the quarter turn Starline Cryo Star Ball Valve offers high flow capacity, reliability and tight shutoff with unidirectional flow on floating ball body designs and bidirectional on trunnion mounted.

An unrivalled thermal shock test performance and fire test designs make the Cryo Star Ball Valve an immediate choice for critical service and applications. Witness Cryogenic testings includes BS6364, SHELL SPE 77/306, TOTAL GS PVV150, AGIP SPEC 1111544.PIP.MME & ENI SPEC GA-18
