哈威節(jié)流閥作用是通過有效的螺紋長度達(dá)到的。哈威Q，QR與QV型閥均有5種規(guī)格，并在蓄能器油路和控制油路中用作流量控制。哈威Q型節(jié)流閥采用全行程恒定節(jié)流面積的開口式閥芯結(jié)構(gòu)，對微小污垢不敏感（無縫隙過濾作用）。哈威FG型微量節(jié)流閥也可用于換向閥換向時間的調(diào)節(jié)，并避免切換時流量沖擊及阻尼振動。QR50T12專賣店HAWE哈威節(jié)流閥

Throttles are a type of metering valve. The valve types Q, QR and QV are subdivided into five sizes and are used to limit the flow in accumulator and circuits. They are designed as slot-type throttles （complete stroke） and are therefore impervious to micro-contaminants （no edge filter effect）. The precision throttle valves type FG are preferentially used for adjusting the switching time of directional valves, preventing pressure surges and damping oscillations. The throttle effect is achieved via the effective thread length. The settings can only be adjusted using tools. |
