Right Angle Flow Control Valves
General Information
Parker offers a wide range of fow controls to meet a large variety of
applications. Parker fow controls are designed for mounting directly
onto the cylinder ports to provide precise control of piston rod speed.
Due to their compactness they are particularly suitable for applications
where space is at a premium.
General Principle
The piston rod moves as a result of the pressure differential on either
side of the piston. The speed of the rod is normally determined by the
exhaust air fow from the cylinder, although certain applications require
control from the inlet. The control of the air fow is via an adjustable fow
control valve installed on the exhaust port.
Operation
The mounting of two fow controls on a cylinder permits speed control
of the cylinder rod in both directions. Air passes freely through the fow
control valve A, with the check valve in the open position. The exhaust
is controlled by the fow control valve B, where the check valve in the
closed position forces the air to go through the adjustable needle valve.
The function of A and B are reversed when inlet air is applied to port B.
Advantages
• Direct mounting
• Compact
• Positional
• Optimum fow control
• Swivel outlet for use where access is restricted
