4820-17-118-2193 4820171182193 171182193 is a valve with a bolt or stem that may be mechanically actuated to two different positions by rotary or linear motion. in the first position, the valve disk is located and locked against the seat permitting no fluid flow through the valve. in the second position, one side of the valve disk is located against the seat permitting movement of the disk in a manner that will allow a flow of fluid in one direction through the valve. the valve disk may be spring loaded. it may be inline or cartridge (manifold) design. see also valve (1), lift-check and valve (1), stop-lift-check.

5961-99-118-2193 5961991182193 991182193 is two or more interconnected semiconductor device (1), diode arranged in stack(s) for use in power supplies to change alternating current to direct current. for items containing material such as selenium or copper oxide, see rectifier, metallic.

6120-13-118-2193 6120131182193 131182193 is a transformer consisting of one or more primary winding(s) and one or more secondary winding(s). it may be designed for direct connection to an alternating current source for purposes of changing the secondary volts and amperes or designed to eliminate metallic interconnection between circuits in an overall one to one voltage ratio, with or without additional output windings, or items designed to automatically maintain a constant output voltage within specified limits under varying input or load conditions. also includes items having a provision for mechanically changing the turns ratio or inductive coupling in progressive increments by means of voltage taps, ratio adjuster, or devices oe similar design. for transformers having winding(s) common to both input and output circuits, see transformer (1), power, autotransformer. excludes transformer (1), pulse.
