Three-way ball valves BVT..K series

The three-way ball valves are classified as “Pressure accessories” in the sense of the PED Directive 2014/68/EU, Article 2, paragraph 5 and are subject of Article 4, paragraph 1, letter (c), of the same Directive. All the product range is suitable for use with refrigerant R744 (CO2), classified in Article 13, paragraph 1, letter (b), of PED Directive 2014/68/EU as part of Group 2, therefore not toxic, not inflammable and not explosive fluid and indicated in A1 Group of Annex E of standard EN 378-1. For any different application is suggested to contact directly the technical department.

The three-way ball valve allows directing the flow from the central connection to the two longitudinal ones.


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

NOTE: The entire range of three-way ball valves could be motorized using AMBV adaptors as indicated in the following table. This solution makes possible the remote control of the opening and closing of the valve.


We recommend installing the product with the vertical motorizable axis and in a position that allows an easy installation of the motor. The brazing of the valves on the system shall be done with a low melting point alloy. During this process do not point the flame directly towards the body keeping it cooled in order to avoid compromising the seal of the gaskets.
