Castel diaphragm valves areparticularly suitable for use onrefrigerating systems operatingwith refrigerant fluids CFC,HCFC and HFC.
Diaphragm valves don’t havegland seal. External sealing isensured by thin metal discs(diaphragms) ensuring hermeticsealing of the area throughwhich the fluid flows.
The materials used for the mainparts are:• ST-UNI EN 12165 - CW 617N
hot-forged brass for the bodyand the cap;
• nylon for the seat sealinggasket;

GLOBE VALVES
Globe valves can be used onrefrigerating systems in order tointercept the refrigerant fluidsCFC, HCFC and HFC.
Globe valves are manufacturedin two basic types: 6510 withstraight connections and 6530with angle connections.Valves 6520, which havestraight connections, aresupplied with flanges. In thisapplication, copper pipe issoldered on a brass bush andnot directly on the valve.Globe valves have large orificesto keep the pressure drop to aminimum. On the top of thecaps there is a square seat,fitting it on the spindle it ispossible to use the cap as anoperating wrench.
The materials used for the mainparts are:• ST-UNI EN 12165 - CW 617N
hot-forged brass for body,plug and cap;
• especially treated steel forspindle;
• aramidic and chloroprenegaskets for gland seal;

These valves are normallymounted on the body of therefrigerating compressor, onboth suction and dischargesides. They can be used withrefrigerant fluids CFC, HCFCand HFC.
Compressor valves have athreaded connection that canbe used both as charging orgauge connection. Thecharging connection is cut offby the back-seating of thespindle. The compressor valvesare oval flanged with SAE-FLARE connection to fit copperpipes through a suitable nut.
The materials used in theconstruction of the main partsare:• ST-UNI EN 12165 - CW 617N
hot-forged brass for thebody, flange and bush;
• especially treated steel forthe spindle;
• aramidic and chloroprenegaskets for the gland seal;
• steel for the cap;• glass reinforced PBT for the
