SL042 Low Permeability Temperature Range -40 degrees to 100 degrees C (-40 degrees to 212 degrees F) Constructed of materials having an average magnetic permeability not exceeding 1.05. SL043 US Navy (bronze) Designed to US Navy specifications, following MILV24624, Type 3 and 4, utilizing bronze/non-ferrous materials. SL044 US Navy (ductile) Designed to US Navy specifications, following MILV24624, Type 1 and 2, utilizing nodular cast iron and corrosion resistant steel. SL050 Submersible (crude oil/sea water) Temperature Range 0 degrees to 60 degrees C (32 degrees to 140 degrees F) This specification was primarily designed for in tank locations of crude oil. Tankers carry either crude oil or sea water ballast subject to a maximum head of 25 metres (82 feet). SL052 Submersible (mixed and refined products) Temperature Range 0 degrees to 60 degrees C (32 degrees to 140 degrees F) Similar to SL050 with the exception that all of the sealing elements are of an inert type such as P.T.F.E. and will not subsequently break down due to attack by mixed product cargos. Units submerged in refined petroleum products, such as petrol, diesel oil and aviation spirits, require this specification and for all such enquired we wish to know the range of products that are likely to be involved in order that compatible materials are selected. SL060 Fire Safe Temperature Range -40 degrees C (-40 degrees F) to Fire Condition All sizes of manual gear operators can be built to this specification which includes special bearings and lubrication. Development and testing has been carried out in conjunction with valve makers in accordance with BS5146: 1974 which requires the valve to operate satisfactorily after the fire. SL070 Buried Service (dry chamber) Temperature Range -40 degrees to 100 degrees C (-40 degrees to 212 degrees F) For dry applications subject to occasional flooding by fresh water. Stainless steel input shaft eliminates possibility of corrosion and seizure.
