產(chǎn)品概述
34S※-B20H-W手動(dòng)閥是一款廣泛應(yīng)用于液壓系統(tǒng)的方向控制閥門，采用杠桿操作設(shè)計(jì)，主要用于改變液流方向或切斷液流通路。該型號(hào)閥門具有結(jié)構(gòu)緊湊、流通能力大、穩(wěn)定性高等特點(diǎn)，適用于工程機(jī)械、煤礦機(jī)械、化工設(shè)備及機(jī)床等工業(yè)領(lǐng)域。其閥芯定位方式分為鋼珠定位型和彈簧復(fù)位型，可根據(jù)實(shí)際需求選擇不同功能版本（如34SM-B20H-W為鋼珠定位型，34SM-L10H-T為彈簧復(fù)位型）。產(chǎn)品采用優(yōu)質(zhì)材料制造，確保在高壓環(huán)境下穩(wěn)定運(yùn)行，并兼容多種液壓油介質(zhì)。323
技術(shù)特點(diǎn)
該手動(dòng)閥采用三位四通或二位四通設(shè)計(jì)，閥芯中位可提供多種滑閥機(jī)能選項(xiàng)（如交叉相通或直通模式），滿足不同工況的油路控制需求。產(chǎn)品重量輕、體積小，安裝尺寸兼容標(biāo)準(zhǔn)液壓系統(tǒng)（如上海型設(shè)計(jì)安裝尺寸為92×77×130mm，螺釘規(guī)格M14/M12），便于集成到現(xiàn)有設(shè)備中。閥門內(nèi)部采用精密加工的滲碳合金鋼部件，經(jīng)磨削處理確保長期耐磨性，工作壓力范圍覆蓋中高壓場景。此外，產(chǎn)品支持板式螺釘連接或法蘭安裝，適配不同管道布局要求。5613
應(yīng)用場景
34S※-B20H-W系列手動(dòng)閥適用于需要頻繁換向操作的液壓系統(tǒng)，典型應(yīng)用包括：工程機(jī)械的行走馬達(dá)控制、煤礦設(shè)備的液壓支架調(diào)節(jié)、化工生產(chǎn)線的流體分配控制，以及機(jī)床工作臺(tái)的進(jìn)退刀液壓驅(qū)動(dòng)。其設(shè)計(jì)兼顧室內(nèi)和戶外使用環(huán)境，防護(hù)等級(jí)可滿足一般工業(yè)防塵需求。用戶可根據(jù)實(shí)際工況選擇不同通徑（如10L、20L、32L）和接口規(guī)格（如7/8-14UNF螺紋）。11924
產(chǎn)品優(yōu)勢(shì)
與同類產(chǎn)品相比，該手動(dòng)閥在以下方面表現(xiàn)突出：1) 優(yōu)化的流道設(shè)計(jì)降低壓力損失，提升系統(tǒng)能效；2) 手柄操作力矩小，減少人工疲勞；3) 密封結(jié)構(gòu)采用耐油橡膠與金屬組合，有效防止泄漏；4) 可擴(kuò)展兼容電磁先導(dǎo)控制模塊，實(shí)現(xiàn)手動(dòng)/自動(dòng)雙模式切換。產(chǎn)品經(jīng)嚴(yán)格出廠測試，包括耐壓試驗(yàn)和換向可靠性驗(yàn)證，確保長期使用穩(wěn)定性。82830
英文介紹 (Product Description)
The 34S※-B20H-W manual directional control valve is designed for hydraulic systems requiring reliable flow path switching. Featuring lever-operated mechanism, it provides precise control of fluid direction in applications such as construction machinery, mining equipment, and industrial automation. The valve offers three-position/four-way or two-position/four-way configurations with optional spring return or detent versions (e.g., 34SM-B20H-W for detent type, 34SM-L10H-T for spring return).
Constructed with hardened alloy steel components and precision-ground spools, it ensures durability under pressures up to 31.5MPa. Standard mounting interfaces include ISO 4401 pattern with M14/M12 fasteners, compatible with most hydraulic power units. The compact design (92×77×130mm for Shanghai-type) simplifies installation while maintaining high flow capacity.
Typical applications involve directional control of hydraulic cylinders, motor speed regulation, and pressure circuit selection. The ergonomic handle reduces operator effort, and the modular design allows customization of port configurations (e.g., 7/8-14UNF ports). Optional middle position functions (open center, closed center, float) provide flexibility for diverse system requirements. 51125
This product line complies with general industrial performance expectations, offering consistent operation across temperature ranges of -20°C to +80°C. The corrosion-resistant surface treatment and nitrile sealing elements ensure reliable service life in typical hydraulic oil environments. Customers may select from multiple actuator options including extended levers or rotary knobs for specialized applications. 132729
