    Parker 針閥
    Parker Needle Valves
    針型流量控制閥Needle Flow Control Valves

    派克可提供基本的針閥及帶反向旁路單向閥的針閥, 針閥是無壓力補償的可調節流閥, 派克提供的大規格針閥的通流能力達 60 gpm (225 Lpm), 工作壓力可達 6000 psi (420 bar)。 Parker offers standard needle valves and needle valves with a reverse free-flow check. Parker's needle valves are non-compensated adjustable orifices capable of flows up to 225 lpm (60 gpm) and pressures as high as 420 bar (6000 psi).

     

     

    派克的針閥系列具有高度耐污染的設計,允許通過手動調節進行精細計量,以創建和調節流量。 這些閥可以在液壓系統流量高達225 lpm和壓力高達420 bar的情況下運行,并且可以選擇集成反向自由流止回閥。 派克的針型閥或針型止回閥是汽缸或電機控制和/或放氣應用的理想選擇,適用于廣泛的市場,例如農業,建筑,物料搬運,工業,石油和天然氣等。 Parker's family of needle valves feature a highly contamination tolerant design that allows for fine metering with manual adjustment to create and orifice and control flow. These valves can operate with hydraulic system flows as high as 225 lpm and pressures up to 420 bar with the option of an integrate reverse free-flow check valve. Parker's needle valves or needle-check valves are ideal for cylinder or motor control and/or bleed-off applications within a broad range of markets, such as the agriculture, construction, material handling, industrial, oil & gas, and several more.

    其他技術洞察Additional Technical Insight:

    針閥為需要基本調節液壓流量的應用提供了經濟的解決方案。閥內的有效孔口尺寸可通過調節螺釘或旋鈕來改變,并且可以通過添加可選的蓋使閥具有防篡改功能。當閥門完全關閉時,可以實現關閉。設置好調整后,閥門將充當固定孔。像所有固定孔一樣,任何壓力變化都會引起流量變化。如果需要恒定流量而不管系統壓力或負載壓力如何,請考慮使用派克的壓力補償流量控制器。派克的J02A2,NVH081,NVH101和J06A2插裝閥是標準的2通針型閥,具有微調選項?装鍖⒃趦蓚方向上計量,但從端口2到1的流量是優選的。如果需要無限制的回流,則這些針型閥將需要使用額外的止回閥。派克還提供帶有內部反向自由流檢查功能的J02B2,FV101和FV102針形閥,以減小歧管尺寸和組件數量。Needle valves offer economical solutions for applications that require basic adjustable control of hydraulic flow. The effective orifice size inside the valve is varied with screw or knob adjustments and the valve can be made tamper resistant with the addition of an optional cap. Shutoff can be achieved when the valve is adjusted completely closed. Once the adjustment is set, the valve acts as a fixed orifice. Like all fixed orifices, any changes in pressure will cause changes in flow. If constant flow is required regardless of system or load pressure, please consider Parker's pressure compensated flow controls. Parker's J02A2, NVH081, NVH101, and J06A2 cartridges are standard 2-port needle valves with fine adjustment options available. The orifice will meter in both directions, but flow from port 2 to 1 is preferred. If unrestricted reverse flow is required, an additional check valve will need to be used with these needle valve versions. Parker also offers J02B2, FV101, and FV102 needle valves with internal reverse free flow checks in order to reduce manifold size and component quantities.
