哈威单向节流阀 RDF3*现货

哈威节流阀属于流量控制阀，在液压装置中被用作流量调节。通过调节阀的开口面积，来改变通过阀的流量，同时在阀的进口处产生一个背压，使得泵的部分流量旁通，部分流量（剩余流量）通过该阀，剩余只能保证部分有效流量通过节流阀。如果背压发生变化，旁路流量也发生变化，哈威单向节流阀 RDF3*现货

哈威单向节流阀 RDF3*现货 哈威RD（F）/ED型节流阀，哈威流量控制阀，哈威RD（F）/ED型单向节流阀的技术参数：

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）.
