Linear actuator set at one of three positions by supplying gas at suitable pressure. Designed for use as part of relief valve in system storing liquid oxygen. Stops at any of three positions, depending on pressure at supply port. Seals made of polytetrafluorethylene for low friction at low temperatures. Use of polytetrafluoroethylene and large clearances reduces friction and makes possible operating over range of temperatures from -420 to 250 degree F (-251 to 121 degree C).
