MATERIALS

The body and the chromium plated ball are manufactured in hot-forged brass EN 12420 -CW617N; the solder

connections are in copper tube EN 12735-1-Cu-DHP. The spindle is in especially treated steel and the groove is in stainless steel.

The electric welding of the bodies and the Chloroprene rubber (CR) for outlet seal gaskets, si assembled on the spindle, to prevent any leaks. At last, specifically modified PTFE seat ball gaskets ensure low working torque and prevent any leaks. The special design of ball valves permits: the bi-directional flow of the refrigerant and consequently, the assembly on the plant without considering the direction of the refrigerant – ensures the internal equilibrium of pressures when the valve is closed – prevents any risk of ejection of the spindle.
