11 M9-3
		M9-3 Series “M9-3” control valves have been designed to meet the most specific fluid adjustment requirements in a plant. They can be employed as three-way mixing valves (two incoming fluids and only one exit) with fluid tending to open the plug, or as three-way diverting valves (one incoming fluid and two exits) with fluid tending to close the plug. The control valve allows to modify the flow shifting from very high flows to remarkably reduced flows with an endless range of adjustments. This aim has been achieved through the standard use of technical-manufacturing devices such as: • EQP=% equipercentage plug that, further to equal increases of the opening stroke, allows a consequent flow increase with constant percentage in comparison with the previous value. • Controlled valve stem with perfectly balanced movement thanks to the presence of a bottom guide. • Self-adjusting stuffing box ensuring a perfect seal on the stem.
