FLIGHT International, 6 September, 1962 Another new development in flight equipment. . . The remote control of high pressure gas in aircraft or guided weapons systems is among the uses of these typical Hymatic servo stop valves.They are small and light, use little current, have exceptionally low leakage and give high-speed response. Type tested and fully approved, the three-way valve MD30 is for pressures up to 3,000 p.s.i., has I in. B.S.P. connections and weighs only 2\ lb. It is rated at 0.4 amp., 24 volts continuous operation, and works under I3g down to 16 volts. Positive non-operation below 10 volts gives added safety. The MD23, using many common parts, is a two-way valve handling pressures up to 4,500 p.s.i. It has \ in. B.S.P. connections, weighs 1.9 lb. and uses 0.4 amp. at 24 volts. Hymatic, as leading engineers in the aircraft equipment field, have been respon sible for the design and precision manufacturing of many products, including Selector valves • High pressure relief valves • Pneumatic rams • Hot air reducing valves Shuttle valves • Automatic regulator valves • Pressure maintaining valves THE HYMATIC ENGINEERING COM PA NY LIMITED •Vedditch • Worcestershire u,,E
