DA-30/先導(dǎo)式卸荷閥產(chǎn)品介紹（中文版）
DA-30系列先導(dǎo)式卸荷閥是一款專為工業(yè)液壓系統(tǒng)設(shè)計的高效壓力控制裝置，適用于多種復(fù)雜工況下的系統(tǒng)壓力調(diào)節(jié)與安全保護。該產(chǎn)品通過先導(dǎo)式結(jié)構(gòu)設(shè)計，實現(xiàn)了對主閥芯的精準(zhǔn)控制，能夠在預(yù)設(shè)壓力范圍內(nèi)快速響應(yīng)，有效平衡系統(tǒng)負載波動，確保設(shè)備穩(wěn)定運行。
本產(chǎn)品采用模塊化設(shè)計理念，主體結(jié)構(gòu)由高強度合金材料經(jīng)精密加工而成，內(nèi)部流道經(jīng)過優(yōu)化處理，顯著降低壓力損失。其核心特點體現(xiàn)在靈敏的啟閉性能和寬泛的壓力調(diào)節(jié)范圍，用戶可根據(jù)實際需求在10-350bar區(qū)間內(nèi)靈活調(diào)整設(shè)定值。閥體表面經(jīng)過多層防腐處理，能夠適應(yīng)高濕度、高粉塵等惡劣環(huán)境，延長使用壽命。特殊設(shè)計的密封組件可有效避免內(nèi)泄漏問題，在長期使用中保持穩(wěn)定的壓力控制精度。
DA-30卸荷閥適用于工程機械、冶金設(shè)備、船舶液壓系統(tǒng)等領(lǐng)域，尤其適合需要周期性卸荷的工況場景。在注塑機合模系統(tǒng)、鍛壓設(shè)備液壓站、礦山機械動力單元等典型應(yīng)用中，該產(chǎn)品能有效吸收壓力沖擊，防止系統(tǒng)過載。與同類產(chǎn)品相比，其獨特的緩沖設(shè)計可降低約40%的壓力波動，有助于提升關(guān)聯(lián)設(shè)備的運行平順性。維護方面采用可拆卸式濾芯結(jié)構(gòu)，便于日常清潔保養(yǎng)，降低運維成本。
產(chǎn)品提供多種接口規(guī)格（包括ISO標(biāo)準(zhǔn)螺紋和法蘭連接），適配不同管徑需求。出廠前經(jīng)過嚴(yán)格的質(zhì)量檢測流程，包括72小時持續(xù)壓力測試和50000次動作循環(huán)試驗，確保出廠產(chǎn)品符合工業(yè)級可靠性要求。我們提供完善的技術(shù)支持服務(wù)，可根據(jù)客戶具體需求進行非標(biāo)參數(shù)調(diào)整，幫助優(yōu)化系統(tǒng)配置方案。
DA-30 Pilot-operated Relief Valve Product Introduction (English Version)
The DA-30 series pilot-operated relief valve is an advanced pressure control solution engineered for industrial hydraulic systems, delivering reliable pressure regulation and overload protection across diverse operating conditions. Utilizing a pilot-controlled mechanism, this valve achieves precise main spool modulation, enabling rapid response within preset pressure thresholds to maintain system stability during dynamic load changes.
Featuring a modular construction crafted from high-strength alloy materials, the valve incorporates optimized internal flow channels that minimize pressure drop. Its key performance attributes include sensitive actuation characteristics and a broad adjustable pressure range spanning 10-350bar, allowing flexible customization for specific application requirements. The multi-layer anti-corrosion surface treatment enhances durability in challenging environments with high humidity or particulate contamination. Specially engineered sealing assemblies effectively prevent internal leakage, ensuring consistent pressure control accuracy throughout extended service periods.
This valve finds extensive application in construction machinery, metallurgical equipment, marine hydraulic systems, and other scenarios requiring periodic pressure relief. In typical applications such as injection molding machine clamping systems, forging press hydraulic stations, and mining equipment power units, its integrated damping mechanism reduces pressure fluctuations by approximately 40% compared to conventional designs, contributing to smoother system operation. The service-friendly design incorporates removable filtration elements for simplified maintenance, effectively reducing lifecycle costs.
Available with multiple port configurations (including ISO metric threads and flange connections), the DA-30 adapts to various piping dimensions. Each unit undergoes rigorous quality verification processes, including 72-hour endurance testing and 50,000-cycle operational validation, ensuring industrial-grade reliability. Comprehensive technical support services are available, including customized parameter adjustments and system integration consulting to optimize hydraulic circuit configurations for specific operational requirements.
