Description
The basic structure of a shuttle valve is like a tube with three openings; one on each end, and one in the middle. A ball or other blocking valve element moves freely within the tube. When pressure from a fluid is exerted through an opening on one end it pushes the ball towards the opposite end. This prevents the fluid from traveling through that opening, but allows it to flow through the middle opening. In this way two different sources can provide pressure without the threat of back flow from one source to the other.
Characteristic
1.The use of more switches on one machine: by using the shuttle
valve, more than one switch can be operated on a single machine for
safety, and each switch can be placed at any suitable loion. This
appliion is normally used with heavy industrial machinery.
2.Winch brake circuit: a shuttle valve provides brake control in
pneumatic winch appliions. When the compressor is operated the
shuttle valves direct air to open the brake shoes. When the control
valve is centered, the brake cylinder is vented through the shuttle
valve, and the brake shoes are allowed to close.
3.Air pilot control: converting from air to oil results in locking
of the cylinder. Shifting the four-way valve to either extreme
position applies the air pilot through the shuttle valve, holding
the two air-operated valves open and applying oil under air
pressure to the corresponding side of the cylinder. Positioning a
manual valve to neutral exhausts the air pilot pressure, closing
the two-way valves, and trapping oil on both sides of the cylinder
to lock it in position.
4.Standby and emergency systems: compressor systems requiring
standby or purge gases capability are pressure controlled by the
shuttle valve. This is used for instrumentation, pressure cables,
or any system requiring continuous pneumatic input. If the
compressor fails, the standby tank—regulated to slightly under the
compressor supply—will shift the shuttle valve and take over the
function. When the compressor pressure is re-established, the
shuttle valve shifts back and seals off the standby system until
needed again.
