NEWTON SPRL Fuel Selector...
NEWTON CONSULTING offers a range of SPRL branded fuel valves featuring distinct features that make them better than the rest. Ceramic disks have no soft moving/rubbing seals to wear out, unlike other valves but also give an 'indefinite' life with a very smooth light action. The lift and turn selector of SPRL valves is instinctive, secure, and easier to use than the complex 'lift button' type. The locking detents avoid accidental movements. The fixings match most installations, and the internal ports prevent cross feeds, unless 'selected to 'Both'. Their lightweight alloy construction is anodized for protection while the Viton O-ring seals are suitable for all current fuels. Male AN fittings enable plumbing straight into the aeroplane system with no extra fittings required.
The SPRL Valves, as designed, have a very nice 'feel' and are logical in use, however, there is a requirement in FAR 23 whereby the fuel valve must be turned from OFF to an ON selection simply by turning it, i.e. it should not have to be lifted up, pushed down etc, and it should also not be possible to turn it from an ON position to OFF without a dent.
Fittings must be purchased separately. Please refer to the separate NEWTON fittings product presentation.
