Precision valve for control of liquids in e.g. surface treatment systems uses ribbed, resilient membrane as piston guide and acts as partition between high and low pressure zones, without control hysteresis

摘要

Precision valve for control of liquids at pressures up to 4 bars uses a ribbed, resilient membrane (1) as piston guide. This also acts as a partition between the high and low pressure zones, without significant control hysteresis.
