Produce
For over 30 years Solent & Pratt 
Engineering has been at the forefront of the design, development and manufacture of high quality butterfly valves for engineering projects around the world. An absolute commitment to outstanding quality and reliability is the key to our success, particularly in environments such as the oil and gas, chemical, petro-chemical and power generation industries.
       
Design
Valve designs of lightweight construction are advantageous for cryogenic use since the valve mass which must be cooled down from ambient to cryogenic temperatures on start up is much reduced. In addition the lower conductivity of lighter weight valves will assist in reducing heat influx which can occur in heavier design styles of valve.

Solent & Pratt's design team have paid particular attention to these basic design principals in the product suitability of our cryogenic range of valves.

The Solent & Pratt TOSV, Triple Offset Segment Valve with its long life, high integrity on thermal cycling and low operating torques is an ideal valve for cryogenic applications.

Principal of Operation
Cryogenic valves are easily reconisable by their long extension bonnets. The extension should protrude for at least 6" beyond any lagging on the pipework to assist a "boil off" to occur within the bonnet extension. In order for this to occur the valve must always be installed with its extension at an angle not less than 20 centigrade from the horizontal. The vapour pocket which results from the 'boil off' within the extension will prevent the cold media from contacting and freezing the valve stem seals in the packing gland.
