Swagelok Company is a $2 billion privately held developer of fluid system products, assemblies, and services for the oil and gas, chemical and petrochemical, [2] semiconductor, and transportation industries.
Larner–Johnson Valve: needle control valve often in large sizes used in water supply systems; Leaf valve: one-way valve consisting of a diagonal obstruction with an opening covered by a hinged flap; Line blind valve: a thin sheet oriented perpendicular to the pipe. The sheet has a solid end and a flow-through end; sliding it from one position ...
Needle valves are also commonly used to provide shut off for the pressure gauge or on applicators to shut off the supply of NH3 to the knives in anhydrous ammonia (NH3) applications. [2] Since flow rates are low and many turns of the valve stem are required to completely open or close, needle valves are not used for simple shutoff applications.

And like a diode, too much reverse bias can damage or destroy the valve assembly. A transistor is a valve in which a diaphragm, controlled by a low-current signal (either constant current for a BJT or constant pressure for a FET), moves a plunger which affects the current through another section of pipe. CMOS is a combination of two MOSFET ...
