S8A單向閥/S-8A
S8A單向閥產(chǎn)品介紹（中文）
S8A單向閥是一種用于液壓系統(tǒng)的方向控制閥，主要功能是確保油液只能單向流動，防止反向倒流。該閥采用直通式管式連接設(shè)計(jì)，安裝便捷，適用于多種液壓管路配置。閥體材質(zhì)通常為鑄鐵，具有較高的耐壓性能，工作壓力可達(dá)31.5MPa。根據(jù)實(shí)際需求，S8A單向閥提供多種開啟壓力選項(xiàng)（如0.05MPa、0.15MPa、0.3MPa、0.5MPa），可滿足不同液壓系統(tǒng)的背壓或止回需求。其內(nèi)部采用錐形閥芯結(jié)構(gòu)，密封性能優(yōu)異，能有效減少內(nèi)泄漏。該產(chǎn)品廣泛應(yīng)用于工程機(jī)械、冶金設(shè)備、注塑機(jī)等工業(yè)領(lǐng)域，特別適合需要防止油液逆流的液壓回路。31125
S8A Check Valve Product Introduction (English)
The S8A check valve is a directional control valve designed for hydraulic systems, ensuring one-way flow of hydraulic oil while preventing reverse flow. Featuring a straight-through threaded connection design, it offers easy installation and adapts to various hydraulic pipeline configurations. The valve body is typically made of cast iron, providing high pressure resistance with a maximum working pressure of 31.5MPa. Available with multiple cracking pressure options (including 0.05MPa, 0.15MPa, 0.3MPa, and 0.5MPa), it meets diverse system requirements for backpressure or check functions. The conical poppet design ensures excellent sealing performance with minimal internal leakage. This product finds extensive applications in industrial equipment such as construction machinery, metallurgical devices, and injection molding machines, particularly suitable for hydraulic circuits requiring prevention of oil backflow.31525
產(chǎn)品技術(shù)特點(diǎn)
S8A單向閥采用模塊化設(shè)計(jì)，通徑規(guī)格覆蓋6A至30A多種尺寸，可適配不同流量需求的液壓系統(tǒng)。其內(nèi)部彈簧機(jī)構(gòu)經(jīng)過優(yōu)化，能實(shí)現(xiàn)穩(wěn)定可靠的閥芯復(fù)位，確�？焖夙憫�(yīng)和持久耐用。閥體流道經(jīng)過特殊處理，壓力損失小，有助于提升系統(tǒng)能效。該產(chǎn)品支持公制螺紋和英制螺紋兩種接口標(biāo)準(zhǔn)，方便全球不同地區(qū)的設(shè)備配套使用。維護(hù)時(shí)只需定期檢查密封件狀態(tài)，無需特殊工具即可完成基礎(chǔ)保養(yǎng)。1617
Technical Features
The S8A series offers modular design with bore sizes ranging from 6A to 30A, accommodating various flow rate requirements. Its optimized spring mechanism guarantees stable spool resetting, delivering reliable responsiveness and long service life. The specially processed flow channels minimize pressure loss, enhancing system efficiency. With both metric and imperial thread connection options, it facilitates worldwide equipment compatibility. Routine maintenance only requires periodic seal inspection and can be performed without specialized tools.2823
應(yīng)用場景說明
在液壓泵出口位置安裝S8A單向閥可有效隔離系統(tǒng)異常壓力，保護(hù)泵體免受沖擊；在雙泵并聯(lián)系統(tǒng)中能防止高壓泵油液倒灌低壓泵。該閥還可與其他液壓元件組合使用，如與節(jié)流閥構(gòu)成單向節(jié)流回路，或作為執(zhí)行機(jī)構(gòu)的背壓閥使用以提高運(yùn)動平穩(wěn)性。在注塑機(jī)鎖模、起重機(jī)支腿等需要位置保持的工況中，其可靠的鎖止功能可避免設(shè)備意外位移。101216
Application Scenarios
Installed at hydraulic pump outlets, the S8A valve effectively isolates abnormal system pressure to protect pumps from shock. In parallel pump systems, it prevents high-pressure oil backflow to low-pressure pumps. When combined with other components like throttle valves, it forms speed control circuits, or serves as a backpressure valve to stabilize actuator movement. Its reliable locking function proves essential for position-holding applications such as injection molding machine clamping and crane outrigger stabilization.41525
