The mineral oils or lubricants containingmineral oils lead to the swelling and therefore to the damage of EPDM seals. Frost and corrosionprotectors based on ethylene glycol are allowed in 15 - 45 % percentage. All specified informationsare to be found in standard specification sheets.When using HERZ compression unions for copper and steel pipes, the permissible temperatureand pressure information according to EN 1254-2:1998 table 5 must be noted. For plastic pipeconnectors a maximum operating temperature of 80 °C and a maximum operating pressure of 4 barapply, according to the pipe manufacturer’s specifications.Operating dataNominalvalues7761Connectionthread,flat sizesealingfor pipeIron pipeSolderedconnectionfor pipeWeldedconnectionfor pipePress connectionfor pipePipe connectionDN 153/41/21 6220 21121 6236 01211 6240 0114 x 2.0P 7014 41DN 15 3/41/2 x 38 mm1 6220 11151 6236 1116 x 2.0P 7016 41DN 15 3/41/2 x 44 mm1 6220 22181 6236 2118 x 2.0P 7018 41DN 15 3/420 x 2.0P 7020 41DN 15 3/420 x 2.5 P 7021 41DN 20 13/4 1 6220 12 15 1 6236 02 26.5 1 6240 02 16 x 2.0 P 7016 42DN 20 1Reduction 1/2 1 6220 02 18 1 6236 12 Reduction 21 1 6241 02 18 x 2.0 P 7018 42DN 20 122 1 6236 22 20 x 2.0 P 7020 42DN 20 120 x 2.5 P 7021 42DN 20 125 x 2.5 P 7025 42DN 20 125 x 3.5 P 7024 42DN 20 126 x 3.0 P 7026 42DN 25 1 1/41 1 6220 63 28 1 6236 63 33.7 1 6240 63 25 x 2.5 P 7025 43DN 25 1 1/425 x 3.5 P 7024 43DN 25 1 1/426 x 3.0 P 7026 43DN 25 1 1/432 x 3.0 P 7032 43DN 25 1 1/440 x 3.5 P 7040 43DN 32 1 1/21 1/4 1 6220 64 35 1 6236 64 47.5 1 6240 64 32 x 3.0 P 7032 44DN 32 1 1/240 x 3.5 P 7040 44DN 32 1 1/250 x 4 P 7050 44Nuts, connectors and seals are always included in the delivery of HERZ flat-seal connector screws.HERZ Calis TS RD 100 distributor valves are suitable for use as thermostatic control valves forconstantly maintaining room temperature or average temperature in closed cold and hot watercircuits with almost constant volume flows.In the open condition of the thermostatic valve, the through port of the valve is open, and the valve isclosed by a thermostat or a thermal drive, when the branch is open and the through port is closed.FunctioningThe CALIS-TS upper part (DN 15 and DN 20 ) can be changed under pressure by means the HERZChangefix Tool 1 7780 00. Thus faults can be easily rectified at the seal, e.g. from the residue offoreign bodies such as dirt, welding and soldering remains, which can be easily removed. Whenusing the HERZ Changefix tool, the instructions included should be noted.Changing thethermostatic valveupper parts
