Preferred coating for spool valve...

Preferred coating for spool valve...

Preferred coating for spool valve...

(OP)
Hi All,

Just wondering if I could get a few suggestions as to the best coating to reduce / avoid sticking for a 303 SS spool valve (can be another metal if need be).

It will be used in 60 psig hot/cold water mixing with temps ranging from 45F - 70F cold side and 100F - 150F hot side if this matters.

Can anyone recommend a preferred coating that would allow proper operation while minimizing scale build up and not wearing off during valve's expected life (2 yrs)?

Thanks,

Glenn
