Abstract

1312182 Valves NIPPON OIL SEAL INDUSTRY CO Ltd 19 April 1971 [15 April 1970] 20534/71 Heading F2V A valve comprises a housing 40 having coaxial inlet and outlet connections for connection into a fluid conduit. A valve member 54 carried on one end of a bellows 46 co-operates with a seat transverse to the valve axis. The other end of the bellows is fixed to a transverse part 44 which allows flow to the outlet. The valve is operated by variable pressure in the bellows controlled through an external connection 68.
