R804 *Only use specific pneumatic devices. The only pneumatic system items permitted on Robots include the following items:
A. pneumatic pressure vent plug valves functionally equivalent to those provided in the KOP,
Examples of acceptable valves include Parker PV609-2 or MV709-2.
B. pressure relief valves functionally equivalent to those provided in the KOP,
Examples of acceptable valves include Norgren 16-004-011, 16-004-003 or McMaster-Carr 48435K714.
To be considered functionally equivalent the valve must be preset or adjustable to 125 psi (~862 kPA) and capable of relieving at least 1 scfm (~472 cm3/s).
C. solenoid valves with a maximum ⅛ in. (nominal, ~3 mm) NPT, BSPP, or BSPT port diameter or integrated quick connect ¼ in. (nominal, ~6mm) outside diameter tubing connection,
D. additional pneumatic tubing, with a maximum ¼ in. (nominal, ~6 mm) outside diameter,
E. pressure transducers, pressure gauges, passive flow control valves (specifically needle valve), manifolds, and connecting fittings (including COTS pneumatic U-tubes),
F. check and quick exhaust valves, provided that the requirements of R813 are still met.
G. shutoff valves which relieve downstream pressure to atmosphere when closed (may also be known as 3-way or 3-way exhausting valves),
H. pressure regulators with the maximum outlet pressure adjusted to no more than 60 psi (~413 kPa),
I. pneumatic cylinders, pneumatic linear actuators, and rotary actuators,
J. pneumatic storage tanks (with the exception of white Clippard tanks P/N AVT-PP-41),
K. 1 compressor that is compliant with R806,
L. debris or coalescing (water) filters, and
M. Venturi valves (note: the high-pressure side of a Venturi valve is considered a pneumatic device and must follow all pneumatic rules. The vacuum side of a Venturi valve is exempt from the pneumatic rules per a in the blue box below).
The following devices are not considered pneumatic devices and are not subject to pneumatic rules (though they must satisfy all other rules):
a. a device that creates a vacuum,
b. closed-loop COTS pneumatic (gas) shocks,
c. air-filled (pneumatic) wheels, and
d. pneumatic devices not used as part of a pneumatic system (i.e. used in a way that does not allow them to contain pressurized air)
