- The body and the chrome-plated sphere are manufactured in hot-forged brass EN 12420 – CW617N and the solder connections are in reinforced copper UNI EN 12735-1 – CuFe2P.The TIG welding of the body and the EPDM O-ring assembled on the spindle,assure the perfect seal of the valves,while the special modified PTFE gaskets around the ball,ensure low working torque.The design of ball valves permits the bidirectional flow of the refrigerant,the equilibrium of internal pressures when the valve is closed and prevents any risk of ejection of galvanized steel spindle.The groove is made of stainless steel.
