ENGINE FOR THE WESTLAND 'WESSEX' AND BRISTOL 1 192 TWIN-ROTOR HELICOPTERS Combining high performance and low weight, this oil-cooling fan by AIRSCREW plays an important part in the success of the NAPIER 'GAZELLE' gas turbine. Many modern British aircraft are fitted with AIRSCREW fans. They are the product of over30 years' specialised experience in fan design and manufacture. When you have a fan problem you'll get the rightanswer faster if you . . . AIRSCREW An Airscrew specification means what it says THE AIRSCREW CO. & JICWOOD LTD • WEYBRIDQE • SURREY Tel: Weybridge 2242/7 Compact Accessible RELIABLE SP MARK 4 SP MARK 4 SP MARK 4 SP MARK4 The basic features of Sounders Spherical Plug Valve design are retained in the Mark 4 series, now in production, whilst refine- ments enhance the performance still further. The Spherical Plug-—the ideal form for sealing contact—is now HARD COATED and is one of the features that contributed to the successful completion of 4,000,000 operations test to which the prototype Mark 4 was subjected. Rubberised-Fabric Seat Diaphragms occupy less space, respond'more readily to rising pipeline pressure and tighten the down- stream seal more quickly. 'O' Rings augment the sealing between body and end connections. Unit construction of the Motorised Valve, with consequent economy of metal, achieves a new compactness and lightness in powered valves. Reduction gear drive from Plessey motor to valve gives full opening or closing speed of 1 second. Electrics can be changed for maintenance without disturbing the valve or draining the system.
