Re: Automation Direct solenoid question
R66 d reads as follows...
D. Solenoid valves that are rated for a maximum working 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.
This is one of those rules written on industry specifications that are changing. The "working pressure" spec now used by manufacturers are the optimum settings for valve operation not the maximum safe pressure for the device. The max pressure for these valves is 125 psi. Please check the 2016 rules when they are published.
