Flow and differential pressure controller The DKH 512 is a flow and differential pressure controller with a wide range of applications. Perfect for use in district heating substations, central heating and air-conditioning systems. Compact, and featuring an electrophoretically painted ductile iron body for optimum rust protection, the DKH 512 also features two inline valves that keep noise to a minimum. A manual shut-off function ensures easy maintenance. Technical description Application: District heating substations, primary side, as well as in central heating and air-conditioning. Heating and cooling systems with variable flow. Function: Differential pressure control over the load and flow control. Closes at increasing flow or Ap. Dimensions: Pressure class: Differential pressure (ApV): Max. differential pressure: 1600 kPa = 16 bar (AHmax) Min. differential pressure: Low flow (LF): 12 kPa (AHmin) Normal flow (NF): 20 kPa (AHmin) High flow (HF): 40 kPa (AHmin) (Valid for max. position, fully open. Other positions will require lower differential pressure, check with the software HySelect.) Setting range: Differential pressure fixed at 15, 40, 60 or 100 kPa.

Prestrujni ventil Ventil za sniženje tlaka nalazi primjenu u sustavima grijanja i hlađenja promjenjivog protoka. PM 512 odlikuje se mekom NBR membranom dugog vijeka trajanja, a također je opremljen pomoćnom oprugom koja djeluje kao sigurnosna u funkciji otvaranja, u slučaju otkazivanja. Izveden je za jednostavno rukovanje u skučenim prostorima. Tijelo ventila od nodularnog lijeva elektroforetski je obojano, za optimalnu zaštitu od korozije. Tehnički opis Primjena: Sustavi grijanja i hlađenja promjenjivog protoka. Funkcija: Linijski prestrujni ventil s pneumatskom oprugom. Otvara pri povišenju ulaznog tlaka. Dimenzije: Razred tlaka: PN 25 ili PN 16 (DN 100-125) Max. diferencijalni tlak (ApV): 1 600 kPa = 16 bar Područje namještanja: Temperatura: Max. radna temperatura: 100°C Min. radna temperatura: -10°C Radni medij: Voda i neutralni radni mediji, mješavine vode i glikola. Materijal: Tijelo ventila: Nodularni lijev EN-GJS-400 Membrana i brtve: NBR, EPDM Površinska obrada: Elektroforetsko bojanje. Označavanje: TA, DN, PN, Kvs, oznaka materijala i strelica smjera strujanja.
