Depl. 01034-15_Depl. 01034-05 01/04/15 16:25 Pagina 1 Thermostatic radiator valves CALEFFI 220 series 01034/15 GB ACCREDITED replaces 01034/05 GB ISO 9001 FM 21654 Function Thermostatic radiator valves are typically used for regulating the medium flow to the radiators of heating systems. When combined to a thermostatic or thermo-electric control head, they keep the ambient temperature of the room where they are installed constant at the set value. This prevents unwanted temperature rises and achieves considerable energy savings. These valves have a special tailpiece with rubber hydraulic seal, permitting quick, safe connection to the radiator without the use of additional sealing materials. 028 Product range VALVES: For steel pipes: 220 series Angled thermostatic radiator valve for steel pipe sizes 3/8”, 1/2”, 3/4” (*) 221 series Straight thermostatic radiator valve for steel pipe sizes 3/8”, 1/2”, 3/4” (*) 224 series Reverse thermostatic radiator valve for steel pipe sizes 3/8”, 1/2” 225 series Double-angled thermostatic radiator valve for steel pipe sizes 3/8” and 1/2” RH version, 3/8” and 1/2” LH version 225 series Double-angled lockshield valve for steel pipe sizes 3/8” and 1/2” RH version, 3/8” and 1/2” LH version For plastic and copper pipes: 222 series Angled thermostatic radiator valve for copper pipe sizes 3/8”, 1/2” radiator x 23 p.1,5 piping 223 series Straight thermostatic radiator valve for copper pipe sizes 3/8”, 1/2” radiator x 23 p.1,5 piping 226 series Double angled thermostatic radiator valve for copper pipe sizes 1/2” radiator x 23 p.1,5 piping RH and LH version 226 series Radiator lockshield valve for copper pipe sizes 1/2” radiator x 23 p.1,5 piping RH and LH version 227 series Reverse thermostatic radiator valve for copper pipe sizes /2” radiator x 23 p.1,5 piping THERMOSTATIC CONTROL HEADS 200 series Thermostatic control head with built-in sensor with liquid-filled element adjustment scale ? –5 corresponding to 7–28°C 201 series Thermostatic control head with remote sensor with liquid-filled element adjustment scale ? –5 corresponding to 7–28°C 202 series Thermostatic control head with LCD type room temperture indicator adjustment scale ? –5 corresponding to 7–28°C 203 series Thermostatic control head with contact probe for fluid temperature limitation adjustment scale 20–50°C, 40–90°C Code 204000 Thermostatic control head with built-in sensor with liquid-filled element adjustment scale ? –5 corresponding to 7–28°C Code 204100 Thermostatic control head with remote sensor with liquid-filled element adjustment scale ? –5 corresponding to 7–28°C Code 209000 Tamper-proof anti-theft cap for use in public places Code 209001 Special allen key for tamper-proof anti-theft cap * 3/4” with tailpiece without rubber seals Technical specification of valve bodies Technical specification of control heads Material 200/201/202/204 series Body: brass EN 12165 CW617N, chrome plated Adjustment scale: ?–5 Obturator stem: stainless steel Temperature adjustment range: 7–28°C EN 10088-3 (AISI 303) Frost protection cut-in: 7°C Hydraulic seals: EPDM Max. ambient temperature: 50°C Control knob and cap: ABS (RAL 9010) Length of capillary, 201 series and code 204100: 2 m LCD type ambient temperture indicator 202 series: 16–26°C Performance Medium: water, glycol solutions Technical specification of control heads 203 series Max. percentage of glycol: 30% Max. differential pressure with control head fitted: 1 bar Adjustment temperature range: - code 203502 20–50°C Max. working pressure: 10 bar - code 203702 40–90°C Working temperature range of thermal medium: 5–100°C Max. sensor temperature: 100°C Max. pocket pressure: 10 bar Control adjustment scale, 200/201/202/204 series Length of capillary: 2 m 0 ? 1 2 · · · 3 · · · 4 5 5°C 7°C 12°C 16°C 20°C 24°C 28°C Depl. 01034-15_Depl. 01034-05 01/04/15 16:25 Pagina 2 Dimensions RH version C C C 4 2 3 · ···· · 4 2 2 3 1 4 2 3 · ···· · · ···· · ···· · · ?

When the ambient temperature increases, this causes an expansion in volume in the bellows, which, in turn, dilate. When the temperature falls, the Thermostatic valves with angled connections 220 series, with reverse takes place: the bellows contract due to the effect of the straight connections 221 series for steel pipe (3/8” and 1/2”) thrust generated by the return spring. The axial movement of the and thermostatic valves with angled connections 222 series sensitive element is trasmitted to the valve obturator through the and with straight connections 223 series for copper pipe (*); connecting spindle, thus regulating the flow of liquid to the heat with thermostatic control head 200, 201 or 204 series emitter.
