Check for if I've picked the correct flyback and zener diodes for a solenoid valve driver

I want to use an arduino power driver shield which contains the RFP30N06LE MOSFET to drive the 12V version of a solenoid valve which has a power consumption of 2.0 Watts (so 167 mA current draw I think … components to eliminate back EMF which I didn't even realize was an issue until I read some other attempts at driving solenoids with similar circuits (see: How to control a 12V solenoid valve with a mosfet
