STANDARD SPECIFICATIONS: For valves on this page.
Ambient/Media Temperature: 40° to 175°F (4° to 80°C).
Flow Media: Filtered air; 5 micron recommended.
Inlet Pressure: 5 to 150 psig (0.3 to 10 bar).
Signal Pressure: Must be equal to or greater than inlet.
Port Threads: NPT standard, BSPP. For BSPP threads add a “D”
prefix to the model number, e.g. D1868A3005.
Quick cylinder reversal can be a problem if the control valve is at a distance from the
cylinder or otherwise restricts the exhaust flow. A ROSS quick exhaust valve near the
cylinder opens as soon as the controls valve begins exhausting, and thus allows quick
reversal of the cylinder.
ROSS shuttle valves have two inlets and one outlet. The first inlet to be pressurized
is connected to the outlet, and the second inlet is then closed. Thus, a pneumatic
device connected to the shuttle outlet can be operated by either of two control valves
connected to the shuttle inlets.
Automatically blocks one inlet passage when
pressure is applied to the secont inlet. Pressure
to either inlet is channelled to one outlet port.
