Ball valves for refrigerants

Overview – Construction – InstallationCatalogue

The Maximum Working Pressure (MWP or PS) recommended for IGLOO standard ball valves is 45bar (650psi), while for IGLOO reinforced ball valves is 48bar (700psi) and for both we guarantee a leakrate under 1 gram/year of refrigerant
During lab tests, IGLOO ball valves broke over the impressive pressure of 300bar (4,350psi): the security factor adopted is more than 6X, among the highest in the industry

Assembly

IGLOO ball valves have a complitely hermetic construction to prevent refrigerant leakage. It’s not possible to dissassembly IGLOO ball valves because the forged brass body is leak-proof sealed by TIG welding.
The spindle with 2 o-rings is mounted from inside and can’t be ejected by overpressure.
The internal ball has a balanced ports construction in order to facilitate the opening and closing operations under high-pressure condition

Materials

EN 12165 Hot forged brass for the body and the cap, Special Teflon© PTFE and specific Chloroprene CR (Neoprene©) rubber (HNBR rubber on request) for the internal gaskets, EN 12735-1 Copper Cu-DHP for the copper extra-long swaged connection and coated steel / stainless steel for internal metal components
