Application Guide The valve train of the Future since 2005 The ICF valve station is an innovative solution that provides the full functionality of a conventional valve station in a single compact unit. Eliminate project bottleneck: Conventional valve stations of six or more individual components and up to twelve welds. ICF means two welds directly at the job site Down time during service is reduced to a fraction compared to conventional valve trains. The unique design of the ICF ensures a quick pump down and faster access to valve modules. The ICF valve is a compact valve train ready for the jobsite. This solution provides you with a variety of benefits: Designed for Industrial Refrigeration Supplied fully assembled. No need to disassembly prior to installation under normal welding procedures Standard side ports to fit service valves, pressure transmitters, sight glasses. Applicable to all common non flammable refrigerants including R744 and R717. Direct Weld Connections (No leaks through flanges) Compact design, faster service Available with different connection types including ANSI and DIN, Socket weld High capacities low pressure drop Low weight design Approvals ICF valve station Nominal bore DN 25 (1 in.) DN 32-40 (1¼ - 1½ ) Classified for Fluid group I Category Article 3, paragraph 3 II CRN Technical data Refrigerants Applicable to all common non flammable refrigerants including R717, R744 (CO 2 ) and non corrosive gases/liquids dependent on sealing material compatibility.
