RCV and HIGH PRESSURE SWITCH

[abbasi]

hi there
well we want to install Reverse cycle valves for 12, 15 and 20 tons but i cant find any catalogue to select them ,ALCO(now flow controls) made them b4 but in their new cataloge they manufacture only for upto 6 tons.
also can we use auto reset switch as HIGH PRESSURE SWITCH, i differ in this regard as it is a safety n b of manual reset type. even a timer with autoreset wont serve purpose.
WAT DO U ALL THINK???????

RANCO produces 4-way reverse valve.

And yes, high pressure switch can be auto reset (if safety valves are installed), but in this case you have to ensure prevention of recycling and high diff. pressure, as the pressure will dive quickly when compressor stops.

We use those of Saginomya/Danfoss.
You see those in most Japanese AC's

Try to find Ranco or Danfoss on internet.Ranco have code VH3 1162 for capaciti from 135kW - 538kW with diferent tube conection.

Best regards,
