AB-QM
Danfoss AB-QM je tlačno neodvisni regulacijski ventil (PICV), ki združuje visoko natančnost in trpežnost ter uporabnikom prijazno uporabo, ki je vodilna na trgu. AB-QM je v celoti zasnovan tako, da prispeva k pravočasni izvedbi projekta v okviru predvidenih sredstev in hkrati zagotavlja najučinkovitejši sistem HVAC.
Tlačno neodvisni ventili so regulacijski ventili z avtomatskim hidravličnim uravnoteženjem. Vgrajeni regulator tlaka vzdržuje konstanten diferenčni tlak preko regulacijskega ventila, s čimer zagotavlja polno avtoriteto in avtomatsko omejevanje pretoka. Z združitvijo dveh funkcij (regulacije in avtomatskega hidravličnega uravnoteženja) v eno Danfossovi ventili PICV zagotavljajo stroškovno učinkovito rešitev za izzive, s katerimi se srečujejo v prihodnost usmerjeni projektanti sistemov HVAC. AB-QM se lahko uporablja tudi v industrijskih hladilnih sistemih.
AB-QM ANSI
The AB‑QM control valve provides pressure independent regulation of flow while also providing flow limiting system balance. The valve internally contains a unique differential pressure regulator which automatically adjusts to normal changes in system pressure from valves opening and closing or changing of pump speed. As a result of maintaining a constant pressure for the temperature control valve, valve authority is maintained high. This allows for precise interaction with the temperature controller and unparalleled system operation as indicated by assuring the highest possible coil log mean temperature difference (ΔT).
The valve is easily set and adjusted to provide the precise flow required for each terminal unit. Design calculation and commissioning effort normally required for it's control and balance valves are virtually eliminated because of the built in automatic pressure control regulator. A wide selection of actuators are available for the AB‑QM providing further control features for the valve, making it an ideal selection for the simplest of two position control strategies to the precision required for modulating control and variable speed pump optimization.
