Linear Valve - an overview ScienceDirect Topics

Linear valves used for instrument impulse lines (see Section 3.3.5, Chapter 3 ), may be too small but quarter turn valves should be adaptable. Limit switches provide an electrical signal to indicate the valve end of travel. Switches can be set to show “closed”, “wide open” or two switches can indicate both.

Jul 11, 2008  Abstract: A torque converter lock-up clutch may be controlled by a lock-up clutch regulator control valve. The valve is utilized to selectively direct a fluid to the torque converter or to a pressure regulator valve. For example, in a hydrodynamic condition of the torque converter, the valve permits fluid to flow to the torque converter.

Control Valve Basics: Sizing and Selection

A control valve is comprised of an actuator mechanism that is capable of changing the position of flow controlling element in the valve. The valve modulates flow through movement of a valve plug in relation to the port(s) located within the valve body. The valve plug is attached to a valve stem, which, in turn, is connected to the actuator.
