Products and innovations – summary sheetHERZ thermostaticvalvesTechnically perfectedsystems for thehighest qualitydemandsHERZ thermostatic valves fulfil thehighest requirements of technologyand comfort and they correspond tothe European standard, EN 215. Combinedwith HERZ thermostatic heads, theyhelp to decrease the energy consumption ofevery water heating system and therebythe heating costs. Different designs allowadaptation to any installation conditions sothat the thermostatic head is always installedin a favourable heat flow position.The variety of types guaranteesfurther development and reliabilityA broad variety of body shapes and valvecones are offered to correspond with themost diverse market requirements. On theone hand HERZ invests in the continuoustechnical development of its products andon the other hand HERZ attaches greatimportance to the consistency of majorfunctional parameters to guarantee the replacementof accessories over decades.Therefore the M 28 x 1.5 thread (thermostatichead), the valve closing dimensionund the valve lift remain unchanged foryears. Thus every HERZ thermostatic valvegoing back to 1978 can be retrofittedwith the current HERZ thermostatic heads.Naturally HERZ has its own thermostatichead model (1 7235 01) which isavailable for all thermostatic valves producedprior to 1977. HERZ valve modelsfrom 1977 to 1990 may be retrofitted withthermostatic upper parts (1 6376).Model Colour Protection Pre-setting Single- Dual-pipe Area of applicationcappipeTS 90 White X StandardTS 90 V Red Continuously X District heating,adjustable,StandardconcealedTS 98 V Orange Continuously X District heating,adjustable,Standardwith displayTS FV Cyclam Precise control X District heating,with displaycondensing boilerspre-settingTS 90 E Grey Resistance can X New single-pipe systemsbe reducedTS E White Maximum flow X Gravity systems,old single-pipe systemsCalis White* X Vertical single-pipesystems* (blue for model with 100 % distribution)Tested according to EN 215Today, independent institutes are responsiblefor the control and registration of thermostaticvalves according to the Europeanstandard, EN 215. This testing is periodicallyrepeated so that ongoing conformitywith the standards can be guaranteed.HERZ products are also continuouslytested in-house for conformity to thestandards.According to the standard dimensions forstraight or angle valve models, nowadaysseveral series* such as “F”, “D”, “S” und“GB” are produced in DN 10, 15 and 20.Additionally the series “special angle”(angle valve with flow reversing function)and three-way valves are available. Forsingle-pipe, gravity and steam systems weoffer special valves up to DN 25. In generalall types are equipped with both, a socketthread according to ISO 7/1 for steel pipeconnection and an external thread G 3/4(according to DIN V3838) and M 22 x 1.5with inner cone for copper, soft steel or plasticpipe connection. For special areas ofapplication such as the zone valve, externalthreads with flat seals are also available.Another variant is the thermostatic valvewith an integrated bleeding valve.* D(DIN): The dimensions are based on the former German valvestandard *F (FN): French standard *S: Swedish standard *GB:British standard3/2005Please continue reading on page 10.7➠
