CHARACTERISTICS

The TIG welding of the body and the EPDM O-ring assembled on the spindle, assure the perfect sealing of the valves. The special modified PTFE gaskets around the ball ensures low working torque. The design of these valves permits the equilibrium of internal pressures and prevent any risk of ejection of galvanized steel spindle.

MATERIALS

The body and the chromed ball valve are made of hot forged brass EN 12420 – CW617N and their solder connections can be made of reinforced copper UNI EN 12735-1 – CuFe2P or stainless steel AISI 304 made from drawn tube.

MOTOR CONTROL

The entire product range can be connected with different type of actuators.

Each valve must be connected with actuator through an adapter kit which must create the perfect connection with actuator.

Each actuator has an adapter which indicates the degree of the rotation during the working time. It can be ordered with actuator.
