Ball valves BV..HP / BV..AHP series

The 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.


The body and the chrome-plated sphere are manufactured in hot-forged brass EN 12420 – CW617N and the solder connections are in seamless steel tube AISI 304. 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 bi-directional 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.


During welding, avoid directing the flame directly towards the body, keeping it cooled in order to avoid compromising the seal of the gaskets.
