2 valves for radiator with integrated valve technical description heimeier s with integrated presetting/finest presetting options are suitable for all heimeier thermostatic heads and actuators. the flow ranges for presetting/finest presetting can be set simply and precisely with a key. the selected value can be read off at the front of the. only qualified specialists are permitted to carry out or adjust the setting with the key. Unauthorised persons cant tamper with the setting in the absence of proper tools. the stainless steel spindle is equipped with a double oring seal. the s vhv and vhf with the. 4, 440, 44 and 44 feature 6 presetting/ finest presetting ranges. the s vhv8s and vhf8s with the. 460, 46, 46 and 466 feature 8 infinitely variable presetting/finest presetting values. assembly s with presetting VhV with 6 presetting ranges VhV8s with 8 infinitely variable presetting values s with finest presetting VhF with 6 finest presetting ranges VhF8s with 8 infinitely variable finest presetting values Presetting with just one twist Setting verification option Use of key prevents misuse Lowest possible flow tolerances Optimised flow limitation

3 valves for radiator with integrated valve application the majority of radiators are delivered exfactory with s featuring presetting 4, 440, 460 and 46 (see table). these inserts are intended for twopipe pump heating systems with rmal to high temperature spread as well as for singlepipe heating systems. should it be necessary to use the finest presetting series due to minimal hot water volumetric flow or largescale temperature spread, the installed presetable insert should be replaced by an insert with 44, 44, 46 and 466 finest presetting. heimeier s can be identified by the corresponding 4digit article number on the end face (see illustration). the integrated presetting/finest presetting facility makes exact hydraulic balancing possible with the aim of providing hot water to all heat consumers corresponding to their heating needs. this function operates under the assumption that the set values are actually realised in practical applications. adherence to the lowest possible flow tolerances is imperative for this purpose. heimeier s effectively meet this requirement. experience has shown that the differential pressure across s should t exceed the value of approx. 0. bar in order to ensure lowise operation. if during the planning stages of a system it becomes evident that the system will experience higher differential pressures in the partial load range, devices for regulating differential pressure such as differential pressure controllers or overflow valves are to be installed.

4 valves for radiator with integrated valve sample application. with presetting. factory setting/singlepipe operation. radiators with integrated valves te the composition of the heat transfer medium should conform to vdi guide line so as to avoid damage and the formation of stone deposits in hot water heating systems. Please refer to the vdtüv 466/agfw fw codes of practice for industrial and longdistance heating systems. Mineral oils or all types of lubricants containing mineral oils in the heat transfer medium can have severe adverse effects on the equipment and usually lead to the failure of epdm seals. when using nitritefree antifreeze and anticorrosion agents with an ethylene glycol base, pay particular attention to the information provided by the manufacturer, particularly details concerning the concentration of the individual additives. the s fit all heimeier thermostatic heads and thermal or motordriven actuators. Correctly matching the components will ensure maximum safety and reliability. when using othermake actuators, make sure that the actuating force in the closing range is appropriate for thermostatic inserts with softsealing valve discs. operation Presetting/finest presetting of s VHV and VHF with 6 presetting/finest presetting ranges, e.g. 4/44/440/44 the features 6 flow ranges bordering on each other with out interruption (see illustration). By varying the pband, each range ensures con tinuously variable adjustment or limitation of the radiator mass flow corresponding to the actual heat requirements. this means the can realise quasicontinuously all flow rates between the lowest and highest value without the need to set intermediate values (see illustration). the presetting/finest presetting can be selected between,,, 4, and 6. the setting 6 corresponds to the standard setting (factory setting). the presetting/finest presetting is made by placing the key (. 0.4) on the valve insert and turning it to the required value. the key is then removed. the set value can be read off from the end face of the, i.e. from direction (see illustration). Unauthorised persons cant tamper with the presetting/finest presetting in the absence of proper tools. Presetting/finest presetting of s VHV8S and VHF8S with 8 infinitely variable presetting/finest presetting values, e.g. 460/46/46/466 the s feature an in finitely variable presetting and finest presetting facility. the presetting/finest presetting can be selected between,,, 4,, 6, 7 and 8. 7 intermediate settings are also possible. the setting 8 corresponds to the standard setting (factory setting). the presetting/finest presetting is made by placing the key ( ) on the valve insert and turning it to the required value. the key is then removed. the set value can be read off from the end face of the, i.e. from direction (see illustration). Unauthorised persons cant tamper with the presetting/finest presetting in the absence of proper tools. 4
