kv values Explanation: Refs will follow. -------------------------------------------------- Note added at 15 mins (2015-05-06 23:51:30 GMT) -------------------------------------------------- see: "The kv value expresses the amount of flow in a regulating valve at a given valve position with a pressure loss of 1 bar. The special situation with a fully open valve determines the kvs value. The Kv value expresses the amount of flow in a regulating valve at a given valve position with a pressure loss of 1 bar. The special situation with a fully open valve determines the kvs value. The amount of flow at a lower pressure loss can be calculated using the formula: kv = Q / √ΔP where kv: kv value[m³/h] Q: Flow [m³/h] ΔP: Pressure loss over regulating valve [bar]" (http://uk.grundfos.com/service-support/encyclopedia-search/k... ) -------------------------------------------------- Note added at 18 mins (2015-05-06 23:54:37 GMT) -------------------------------------------------- also written as: "kv value" (with the "v" in subscript), as in here: http://fheprod.danfoss.com/PCMPDF/VDTVP402_IBV_013G1382_83_t... "The kv-values indicate the flow volume (Q) in m³/h at a pressure loss (∆p) across the valve of 1 bar; . At setting N, the kv-value in accordance with EN 215 can be stated as Xp = 2 K. At lower preset values, Xp will be reduced until approximately Xp 0.5 at presetting 1. The table shows the average measured values for integrated valves with radiator. The kvs-values indicate the valve capacity, when the valve is fully open" -------------------------------------------------- Note added at 20 mins (2015-05-06 23:56:59 GMT) -------------------------------------------------- "Kv-waarde; geleidingsvermogen van een klep, kraan of afsluiter." (https://nl.wikipedia.org/wiki/KV ) [links to:] https://nl.wikipedia.org/wiki/Regelklep "Kv-waarde[edit] Het geleidingsvermogen van een klep (het tegenovergestelde van de weerstand) wordt aangegeven door de Kv-waarde (in Angelsaksische landen vaker de Cv-waarde). De Kv-waarde wordt aangegeven als de hoeveelheid doorgestroomd medium (vloeistof, gas) per tijdseenheid bij een eenheid van drukverschil over de klep. Meestal in m³/uur, of liter per minuut, bij een drukverschil van 1 bar. Die waarde varieert met het openingspercentage van de klep. De doorgelaten hoeveelheid (bij een bepaalde klepstand) is evenredig met de wortel uit het drukverschil." -------------------------------------------------- Note added at 22 mins (2015-05-06 23:58:43 GMT) -------------------------------------------------- "Thermostat valve V2000 with VS insert For standard two-pipe heating circuit systems For normal and average water quantities Infinitely variable water quantity (4–130 kg/h) Regulation via valve cone member limiting Integrated flushing position Kv (cv) value: 0.72 […] Thermostat valve V2000 with FV insert For standard two-pipe heating circuit systems For district heating circuit systems (solid metal version) For normal and average water quantities Infinitely variable water quantity (0 – 90 kg/h) Regulation via valve cone member limiting Zero shut-off possible Kv (cv) value: 0.35" (http://www.hydronic-balancing.info/radiator-balancing-60.htm... ) -------------------------------------------------- Note added at 22 mins (2015-05-06 23:59:00 GMT) -------------------------------------------------- or: "cv values" -------------------------------------------------- Note added at 27 mins (2015-05-07 00:03:22 GMT) -------------------------------------------------- "Supplied with integrated adjustable valve (without a thermostatic valve), with Kv value pre-set according to the heat output, CEN certified and tested in accordance with EN215. […] A more PRACTICALLY ORIENTED SOLUTION is to fit the radiators with a Kv pre-set valve in the factory. The principle is relatively simple: the valve ensures that at a given pressure difference the correct quantity of hot water or mass flow passes through the radiator." (http://www.henrad.eu/henrad_en/wp-content/uploads/2013/09/HR... ) -------------------------------------------------- Note added at 36 mins (2015-05-07 00:12:51 GMT) -------------------------------------------------- or: "kv-settings" see e.g.: "The kv-value indicates the water flow (Q) in m³/h at a pressure drop (Δp) across the valve of 1 bar; kv = Q: √Δp. At setting N the kv-value is stated according to EN 215, at XP = 2K i.e. the valve is closed at 2˚C higher room temperature.At lower settings the XP value is reduced to 0.5K of the setting value 1. The kvs-value states the flow Q at a maximum lift, i.e. at fully open valve at setting N. […] The table shows the reduced flow in m3/h when applying different kv-settings: […]" (http://heating.danfoss.com/PCMPDF/VDUVV302_Xtra-Collection.p... ) |
