Shuttle valve (or valve) is a straight stroke valve, is the valve body and actuator into one of the two valves. Shuttle valve is a straight stroke valve, is the valve body and actuator into one of the two valves. Its advantages are small in size, easy to install, and the particularity of the internal piston structure, so that the medium pressure has almost no more resistance to the piston, so as to realize the excellent quality of fast switching and small pressure loss.

Shuttle valve is an excellent design product that is a combination of actuator and valve body. Due to the valve body, piston, valve are made of stainless steel, in appearance more beautiful, high-grade, in actual use seals almost no contact with the medium, has the characteristics of more corrosion-resistant, so that the practical range is wider, plus the internal only one component (piston) in motion, making the movement simple and reliable, long life, even if the maintenance is more simple, and can be installed in any direction.
The working principle of shuttle valve
shut-off valve
Close the valve: when the "A" hole air intake ("B" hole exhaust), the piston to the "D" port movement and pressure on the valve seat seal, the valve is closed. A single-acting normally closed type of spring is mounted in the "A" end of the chamber. In the non-control, the piston is pressed on the valve seat, so the most commonly used is the closed position.
Switching process
Switch process: compressed air from the two holes in a hole into the push piston shaft to move, change the valve on or off the original state.
Normally closed type, close by spring force; Normally open type, open by spring force, open or close time is less than one second.
Open valve
Open the valve: when the "B" hole intake ("A" hole exhaust), the piston shaft from the valve seat to the "C" port direction to move and stop at the end of the stroke, the valve is opened. The single-acting normally closed spring is installed in the "B" chamber. When it is not controlled, the piston shaft is away from the valve seat, so it is most commonly used in the open position.
