DGMX2-3-PP-CW-B-40 Vickers威格士丹佛斯Danfoss疊加型減壓閥 DGMX23PPCWB40

DGMX2-3-PP-CW-B-40｜Danfoss-Vickers 威格士 D03 (NG6) 疊加式 P 口減壓閥（減壓集成內置溢流）

二、核心技術參數

三、閥功能與原理

1. P 路獨立穩壓：主油路 P 進油，閥內部節流降壓后從二次 P 輸出恒定壓力；A、B 直通換向閥，壓力不受本閥控制。

2. 內置溢流保護：穩壓出口超設定壓力，內部溢流通路直接泄油至回油 R，兼具減壓 + 溢流穩壓雙重作用，防止負載超壓。

3. 內控取壓：取樣壓力取自自身二次 P 油口，無需外接控制油。

四、同系列常用衍生型號對照

1. BW：B = 低壓檔 2～4MPa，其余結構同 CW；

2. BH：H = 外置手輪調節（替代螺桿鎖緊，現場便捷調壓）；

3. FW：F = 帶遠程遙控口，可外接遙控調壓閥遠程改壓；

4. -S：氟膠密封，適配磷酸酯、難燃液壓油工況。

DGMX2-3-PP-CW-B-40 Danfoss Vickers Modular Pressure Reducing Valve (Part No.: DGMX23PPCWB40)

DGMX2-3-PP-CW-B-40 | Danfoss-Vickers D03 (NG6) Modular P-Line Pressure Reducing Valve with Integral Relief Function

1. Model Code Breakdown

2. Key Technical Specifications

3. Valve Function & Operating Principle

• Independent P-circuit pressure stabilisation: High-pressure fluid enters via primary P port, throttled internally for pressure reduction before constant regulated pressure is delivered out of secondary P; A and B ports directly feed directional valve without pressure modification by this unit.

• Built-in overpressure relief protection: When outlet regulated pressure exceeds set value, internal relief passage diverts excess oil directly to return port R, combining pressure reduction and relief stabilisation to avoid overload overpressure.

• Internal pilot pressure sensing: Control pressure sampled from the valve’s own secondary P port; no external pilot oil connection required.

4. Common Derivative Models of Same Series

• BW: B = Low-pressure range 2~4MPa, identical construction to CW otherwise

• BH: H = External handwheel adjustment (replaces lock screw for convenient on-site pressure setting)

• FW: F = Equipped with remote pilot port for external remote pressure control via remote relief valve

• -S suffix: Viton seal design compatible with phosphate ester and fire-resistant hydraulic fluids
