2 Tips INTRODUCTION: valves accept flow from two different sources and divert the highest pressure to a single outlet port. valves are commonly used in Load Sensing circuits as well as Brake circuits. Parker offers many different types of shuttles, including ball type, poppet type, spool type. There are a number of configurations available such as cartridge type, insert type, and an in-line version. Ball Type - Cartridge Style The valve consists of a steel ball that can seal against one of two adjacent seats, providing a path from the highest pressure signal to another function. When one inlet port is pressurized, the ball or poppet is forced against the opposite seat, blocking that inlet and providing a flow path to the outlet port. let let let Poppet Type - sert Style This shuttle performs the same function, but allows for higher flow rates due to poppet design. -Line Type This shuttle variant performs the same function in a self-contained body. It can be mounted anywhere on the machine. () () () let let let Bodies & Spool Type - Centered or Spring Offset The spool type shuttle allows for higher flow rates. These are 2 position valves. 1

3 Bodies & Tips 3 Way 2 Position Spool type shuttles are designed to direct flow in such a way as to allow higher pressure signals to open the lower pressure port and connect it to the common outlet port. These spring centered valves will shift when pressure at either end of the spool exceed the spring setting. These are typically used in transmission hot oil shuttle circuits. 2
