Abstract
True flow or velocity valve-controlled systems can only be realized by one of three methods:
-
(1)
Pressure-compensated proportional control valve.
-
(2)
Closed loop system with feedback from actuator.
-
(3)
Closed loop flow feedback system.
The major disadvantages of method (1) are the rather limited degree of load and temperature compensation, 5% being a fairly typical figure, interaction between services supplied from a common power source, and the difficulty of operating overrunning loads under controlled conditions.
