Re: High Flow Solenoids
Be careful to use legal ones. The rules have been opened up quite a bit, and currently state:
R66 The only pneumatic system items permitted on 2015 FRC ROBOTS include the items listed below.
A. Items available in the KOP (except as noted in I),
B. Pneumatic pressure vent plug valves functionally equivalent to those provided in the KOP,
C. Solenoid valves with a maximum 1/8 in. NPT port diameter,
D. Solenoid valves that are rated for a maximum rated pressure that is less than 125 psi rating mandated above are permitted,
however if employed, an additional pressure relief valve must be added to the low pressure side of the main regulator. The
additional relief valve must be set to a lower pressure than the maximum pressure rating for the solenoid valve,
E. Additional pneumatic tubing, with a maximum 0.160 in. inside diameter, functionally equivalent to that provided in the KOP,
F. Pressure transducers, pressure gauges, passive flow control valves (specifically “needle valves”), manifolds, and
connecting fittings,
G. Pressure regulators with a maximum outlet pressure of no more than 60 psi,
H. Pneumatic cylinders,
I. Pneumatic storage tanks (with the exception of White Clippard tanks P/N: AVT-PP-41), and
J. Compressors compliant with R68.
************************************************
My emphasis added.
In previous years, there was a maximum "Cv" rating. this year, it only calls out an 1/8 NPT port size. "High Flow" will be the highest "Cv" rating that still has legal porting.
If you are going for speed, there are other things you will want to investigate as well. If you truly just need higher flow (for whatever reason), find the highest Cv legal device.
