先導(dǎo)式溢流閥，DB30B
產(chǎn)品概述
先導(dǎo)式溢流閥DB30B是一款高性能液壓控制元件，采用二節(jié)同心式結(jié)構(gòu)設(shè)計，由主閥和先導(dǎo)閥組成。該產(chǎn)品適用于各類液壓系統(tǒng)，能夠穩(wěn)定控制油路壓力并防止超壓風(fēng)險。其核心特點是內(nèi)部流道優(yōu)化設(shè)計，具有大流量、低噪聲、響應(yīng)快等優(yōu)勢，可廣泛應(yīng)用于工程機(jī)械、冶金設(shè)備、機(jī)床等工業(yè)領(lǐng)域。16
技術(shù)特點
DB30B采用鋼制主體結(jié)構(gòu)，工作溫度適應(yīng)常溫環(huán)境，密封材料選用耐磨聚酯，確保長期使用穩(wěn)定性。其獨特的先導(dǎo)控制方式可實現(xiàn)精確壓力調(diào)節(jié)，主閥芯與導(dǎo)閥錐閥配合動作，當(dāng)系統(tǒng)壓力超過設(shè)定值時自動開啟溢流功能。產(chǎn)品支持內(nèi)排油或外排油兩種控制油方式，并兼容礦物質(zhì)液壓油介質(zhì)。電磁溢流版本（DBW型）還可通過電磁閥實現(xiàn)遠(yuǎn)程卸荷控制。21114
應(yīng)用場景
該閥特別適合需要壓力穩(wěn)定控制的液壓系統(tǒng)，如注塑機(jī)壓力保持、起重機(jī)安全保護(hù)、液壓站壓力調(diào)節(jié)等場景。其模塊化設(shè)計便于集成到各類液壓回路中，既能作為主系統(tǒng)安全閥使用，也可通過外接控制油路實現(xiàn)多級壓力調(diào)節(jié)。產(chǎn)品提供多種壓力等級選項（50/100/200/315等），滿足不同工況需求。4822
Product Overview
The DB30B pilot-operated relief valve is a high-performance hydraulic control component featuring a two-stage concentric design with main valve and pilot valve assemblies. Engineered for diverse hydraulic systems, it effectively maintains circuit pressure stability while preventing overpressure risks. Its optimized internal flow paths deliver high capacity with minimal noise, making it ideal for industrial applications including construction machinery, metallurgical equipment, and machine tools. 616
Technical Advantages
Constructed with steel housing and polyester seals, the DB30B operates reliably at ambient temperatures. The precision pilot control mechanism enables accurate pressure regulation through coordinated movement between the main spool and pilot cone valve. When system pressure exceeds preset values, the valve automatically activates relief function. It supports both internal and external drain configurations, compatible with mineral-based hydraulic fluids. The solenoid-operated version (DBW type) additionally provides remote pressure unloading capability via electromagnetic control. 111921
Application Flexibility
This valve excels in pressure-critical scenarios such as injection molding pressure retention, crane safety protection, and hydraulic power unit regulation. Its modular architecture simplifies integration into various circuit layouts, functioning equally well as main system relief valve or multi-stage pressure controller with external pilot lines. Multiple pressure range options (50/100/200/315 etc.) accommodate diverse operational requirements across industries. 222426
