			'''Metering Valves''' that are designed to provide accurate and stable control of flow rates in analytical,instrumentation,and research applications.It is a valve with infinite positioning and variable control that is capable of regulating the flow of fluid. A needle valve is a type of metering valve.

These valves generally have low flow rates and high pressure differentials.

			* Pump pressure
			* Operating viscosity of the oil
			* Geometry of the centralized lubrication system
			* Line cross-sections
			* Back pressures downstream of the metering valve distributor

	~~Pump pressure~~		Metering valve systems are often operated with [[Piston Pumps]] that distribute the pump's entire volume throughout the system with each delivery stroke. For the lubricant to be apportioned as desired it is necessary for the hydraulic resistance of the metering valves to be greater than the pressure losses in the tubing.
