Liquid Injection Valve Series L Exchangeable Power Assemblies and Orifices Superheat selection 74 Features • Applications for Series L valves include superheat control (desuperheating of suction gas i.e. in hotgas bypass systems and interstage cooling in multiple stage compressors) • Modular design for economical logistics and easy assembly and servicing • Very good stability is attained because of the large forces generated by the large diaphragm diameter • High quality materials and processes for high reliability and long lifetime • Superior partial load performance due to seat orifice design (LJRE, LERE & LIRE) • Capillary tube length 3 m • PS: 31 bar, TS: -45 ... +65°C • No CE marking according art. 3.3 PED 97/23 EC Type Code Valve Series External Equalizer Capacity Code Charge Code Flange Style WL=Angle Style DL=Straight through Connection * Charge Refrigerant Code R 134a R 22 R 404A R 407C R 507 CL – 15 K 22 K 13 K 22 K GL 15 K 30 K 35 K 25 K 35 K UL 30 K 45 K 40 K * Please indicate designation character for desired superheat LCLE LCL E 4 CL WL 10x16 Type Code XB1019 CL - 2 B Power Assembly Charge Code Capillary Tube Length (3 m) External Equalization Connections Series Nominal Capacity Q n Orifice Standard Flange, Angle Power kW Solder/ODF Assembly R 134a R 22 R 404A R 407C R 507 mm inch 1 * 1,5 1,9 1,3 2,1 1,3 X 22440-B1B 2 * 2,9 3,7 2,6 4,0 2,6 X 22440-B2B C 501 – 5 mm C 501 – 5 3 * 6,1 7,9 5,6 8,5 5,6 X 22440-B3B 10 x16 3/8 x 5/8 3,5 * 9,3 11,9 8,4 12,9 8,4 X 22440-B3,5B LCLE 4 * 13,5 17,3 12,2 18,7 12,2 X 22440-B4B 6 * 17,3 22,2 15,7 24,0 15,7 X 22440-B5B C 501 – 7 mm C 501 – 7 7 * 23,6 30,4 21,5 32,9 21,5 X 22440-B6B 12 x 16 1/2 x 5/8 XB1019…2B 9 * 32,0 41,1 29,0 44,4 29,0 X 22440-B7B A 576 mm A 576 10 * 37,2 47,8 33,8 51,7 33,8 X 22440-B8B 16 x 22 5/8 x 7/8 (22 x 28 ODM) (7/8 x 1 1/8 ODM) 11 * 45 58 40 62 40 X 11873-B4B 10331 10331 LJRE 12 * 57 74 51 80 51 X 11873-B5B 22 x 22 7/8 x 7/8 13 * 71 91 63 99 63 X 9117-B6B (1 1/8 x 1 1/8 ODM) LERE 14 * 81 104 72 112 72 X 9117-B7B 9153 9153 15 * 112 143 99 155 99 X 9117-B8B 22 x 22 7/8 x 7/8 XC726…2B 16 * 135 174 120 188 120 X 9117-B9B (1 1/8 x 1 1/8 ODM) LIRE 17 * 174 223 154 241 154 X 9166-B10B Nominal capacity (Qn) is based on the following conditions: Refrigerant R 407C R 22, R 134a, R 404A, R 507 Evaporating temperature +4°C dew point Condensing temperature +38°C bubble p. +43°C dew point Subcooling 1K +4°C +38°C 1K Valve selection at other operating conditions see page 75.
