www.emerson.comControl Valves Fisher ET, EAT, and ETR general-purpose control valves (figures 2, 3, and 4) are used for throttling or on-off control of a wide variety of liquids and gases. All three valve designs have single ports, balanced valve plugs, and cage guiding. Metal-to-PTFE seating for stringent shutoff requirements is standard in all valves except
Flow Control/ Check Valves - Parker Hannifin
www.parker.comSeries F flow control valves from Pioneer allow the end user to utilize the color-band reference on the valve stem as a great convenience and time-saver when resetting the valves. The Series N needle valves have the same Colorflow feature and are ideal as speed controls on hydraulic and pneumatic circuits where a reverse flow check is not needed.
Head Pressure Control Valves - Parker Hannifin Corporation

www.hafner-pneumatik.comIn the scheme below two 2/2-way solenoid valves (S1 and S2) are used to control a cylinder with spring return (single acting) C1. Without actuation both solenoid valves are closed. In order to move the piston rod to the outer position (right) S2 has to be actuated . Compressed air is flowing from the so urce through S2 into the cylinder. In
Section 5: Air Brakes - CDL Study
cdlstudy.comMake sure the control is in the "normal" position to have normal stopping power. Many vehicles have automatic front wheel limiting valves. They reduce the air to the front brakes except when the brakes are put on very hard (60 psi or more application pressure). These valves cannot be controlled by the driver.
