HAWE哈威節(jié)流閥屬于流量控制閥，在液壓裝置中被用作流量調(diào)節(jié)。通過調(diào)節(jié)閥的開口面積，來改變通過閥的流量，同時在閥的進(jìn)口處產(chǎn)生一個背壓，使得泵的部分流量旁通，部分流量（剩余流量）通過該閥，剩余只能保證部分有效流量通過節(jié)流閥。如果背壓發(fā)生變化，旁路流量也發(fā)生變化，通過節(jié)流閥的設(shè)定流量仍然不錯不變，單向閥和節(jié)流閥組合的單向節(jié)流閥允許在反向自由通過。哈威單向節(jié)流閥 RDF3*現(xiàn)貨

Throttle valves belong to the flow valve group （ISO 1219-1）. They are used in hydraulic systems as resistance valves. This effect is based on the intentional utilization of the variable |p-Q-characteristic. The flow resistance can be regulated very precisely with both the manually and the tool adjustable version. Size 11 and 21 of type ED （RD） are basically designed as slot-type throttles, where the cross section is extended by an annular gap only for the last quarter of the stroke i.e. in the range of the greatest opening. Size 31 to 51 of type ED （RD） are pure annular gap throttles. The nonadjustable version RDF... is a orifice type throttle. The check valve is designed as a tilt plate with a low mass, a spring is omitted （no malfunction due to a broken）. The valve opens and closes with the slightest fluid flow. The adjustment spindle is nitrided （making it wear resistant） and is permanently lubed by the hydraulic fluid （maintenance free）. |
