M8 series
The “M8” series control valves are designed to satisfy control needs using a functional and cheap modulating valve. This valve is ideal for controlling fluids in a plant: it modifies the flow rate from high flow rates to very low flow rates, allowing an infinite number of settings.
This has been achieved by standardizing the use of specific production technical devices, specifically:
• EQP=% equipercentage plug, that further to equal increases of the opening stroke, allows a consequent flow increase with constant percentage in comparision with the previous value.
• Optimally driven valve stem for a perfectly balanced movement.
• Self-controlled stuffing pack assuring perfect watertightness.
