RCV and HIGH PRESSURE SWITCH
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???????
Our nose is our personal air-conditioning system: it warms cold air, cools hot air and filters impurities

Re: RCV and HIGH PRESSURE SWITCH
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.

Re: RCV and HIGH PRESSURE SWITCH
We use those of Saginomya/Danfoss.
You see those in most Japanese AC'sIt's better to keep your mouth shut and give the impression that you're stupid than to open it and remove all doubt.
