Introduction
VALVES
Valves control the flow through a metering system. They open the line to initiate custody transfers and
close the line to stop custody transfers. Some valves can partially close, slowing the flow rate to a dwell
flow on preset deliveries. By slowing the flow rate, valves can lessen the hydraulic shock incurred by the
meter system upon shut off and provide accurate preset deliveries. Many valves use solenoid-operated
valves that require a hard-wired data connection to the LectroCount LCR 600. See manuals M400-11 and
M400-40.
