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 their 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'. NEWTON offered valves range from simple V1 and V3, designed to minimise stockholding costs to V6, tapped 10mm for standard Rotax banjo's on the input and 1/4" nps output or V9 and V10 duplex valves, threaded 1/4"nps which will accept 1/4"npt fittings and NEWTON AN-6 banjo assembly.Their lightweight alloy construction is anodized for protection while the Viton O-ring seals are suitable for all current fuels.
NEWTON also offers a variety of adaptors/fittings (purchased separately) which can be used with these valves as normal AN fittings will not fit directly to these valves. Their offered product portfolio includes AN8 Male NPT 1/4" or 3/8", Female 1/4" NPT, Female 3/8" NPT, Female 14mm used for commercial automotive banjo's and Female 1/4"NPS supplied in their -6 banjo assembly.
Their Male AN fittings enable plumbing straight into the aeroplane system with no extra fittings to buy. The lightweight alloy construction is anodized for protection. Viton O ring seals, used as seals to the valve, are suitable for all current fuels. They can be used on experimental aircraft only.
