This scaling can severely inhibit the operation of traditional quarter-turn valves and restrict flow. Another concern is the problem of dewatering, which happens at the point where pressure is shut off. The upstream pressure in the line ahead of a flow control valve will force liquid out of the lime, leaving a very hard, dry plug behind.
