Access Valves
Advantages
Access Valves are designed to offer convenient low cost access
ports for Refrigeration service. All Access Valves feature 1/4" SAE
male fare access ports and are furnished with a fnger tight quick
seal cap. For greater fexibility, all Tees and Crosses are machined
to receive an access core in all 1/4" SAE fare ends. This allows for
2 or more access connections in one ftting plus greater fexibility in
the positioning of the valves. All Access Valves with pipe connections
have internal ODS solder cups so that these valves may be installed
in either of 2 ways.
Applications
Access Valves may be installed in any position on either high or low
side for quick testing, pressure checking, purging or charging.
Valve Bodies
Straight Access Valve bodies are manufactured from brass rod
CA360 or CA345. Shaped Access Valve bodies are manufactured
from brass forge rod CA377. All Access Valve bodies are machined in
accordance with ARI standard 720.
