Applicable to all common non flammable refrigerants including R717 and R744 (CO2) and non-corrosive gases/liquids. Media temperature range: -60 - +120 °C (-76 - +248 °F). ICLX valves are designed for a max. working pressure of 52 bar g (754 psi g). The ICLX external surface is zinc-chromated to provide good corrosion protection. Max. opening differential pressure ICLX 32-150: 28 bar (400 psi) (if external pressure is 1.5 bar (20 psi) higher than inlet pressure on the ICLX valve). Max. opening differential pressure ICLX 32-150: 40 bar (580 psi) (if external pressure is 2 bar (30 psi) higher than inlet pressure on the ICLX valve).
