Functional Description
Shuttle Valves have a free moving shuttle that blocks one of two
inlet ports while the other inlet port is connected to the (com-
mon) outlet port. When a pressure signal enters the port
blocked by the shuttle, it will cause the shuttle to shift over to
close the opposite inlet port. The shuttle will stay there while the
line or chamber connected to the outlet port is charged and/or
discharged and will only shift when pressure is applied to the
inlet port it is blocking at that time.
In logic terms a shuttle valve is an 'OR' - function.
Pressures
Pressure range– Pneumatic: 5 to 200 psi (0.35 to 14 bar)
Hydraulic: 5 to 500 psi (0.35 to 35 bar)
Symbol
Mounting
Preferably with the centerline of the two inlet ports horizontal.
As shown in the drawing above.

SHUTTLE VALVES
a range of Shuttle Valves in different sizes, made from Brass or 316 Stainless Steel
General Description
VERSA Shuttle Valves are constructed of solid Brass or 316
Stainless Steel, with resilient seals providing tight shut off.
Shuttle valves are 3/2 valves, primarily used to charge and dis-
charge a pressure line or chamber from two - or more -
sources. A typical schematic is shown below:
