4A220-08二位五通雙氣控閥
產(chǎn)品概述
4A220-08二位五通雙氣控閥是一種專為氣動系統(tǒng)設(shè)計的換向控制元件，采用內(nèi)部先導(dǎo)式結(jié)構(gòu)，適用于驅(qū)動氣缸或控制氣動回路的方向切換。該閥體材質(zhì)為鋁合金，具有輕量化、耐腐蝕的特點，公稱通徑為PT1/4（G1/4），工作壓力范圍0.15~0.8MPa，可在5~50℃的環(huán)境溫度下穩(wěn)定運行。其雙向流動設(shè)計支持高效的介質(zhì)傳輸，適用于過濾后的空氣介質(zhì)，無需額外潤滑。閥體采用螺紋連接形式，便于安裝與維護(hù)，廣泛應(yīng)用于自動化設(shè)備、工業(yè)機(jī)械等領(lǐng)域。169
功能特點
4A220-08雙氣控閥的核心功能是通過氣壓信號控制閥芯位移，實現(xiàn)氣路的快速切換。其滑柱式結(jié)構(gòu)結(jié)合特殊工藝加工的閥孔，確保密封性能優(yōu)異且摩擦阻力小，響應(yīng)靈敏。雙氣控設(shè)計賦予其記憶功能，即閥芯位置可通過氣控信號保持，無需持續(xù)供壓。此外，該閥支持集成閥組安裝，節(jié)省空間，并能適應(yīng)頻繁動作需求（最高頻率達(dá)4次/秒）。排氣口可選配消聲節(jié)流閥以降低噪音。91119
技術(shù)參數(shù)
產(chǎn)品工作介質(zhì)為經(jīng)40微米過濾的干燥空氣，有效截面積16.0mm²（CV值0.89），最短啟動時間0.05秒。接口配置包括1個進(jìn)氣口（P）、2個工作口（A/B）和2個排氣口（R/S），其中主接口螺紋為RC1/4，排氣口為RC1/8。閥體耐壓上限為1.2MPa，適應(yīng)-5~60℃的環(huán)境溫度。產(chǎn)品重量約0.225kg，緊湊的設(shè)計使其適用于空間受限的應(yīng)用場景。71419
應(yīng)用場景
該閥適用于雙向氣缸控制、氣動夾具、包裝機(jī)械及自動化生產(chǎn)線等場景，尤其在需要穩(wěn)定換向與記憶功能的系統(tǒng)中表現(xiàn)突出。例如，在驅(qū)動雙作用氣缸時，可通過雙氣控信號實現(xiàn)活塞桿的伸縮定位。其耐壓與耐溫特性也使其適用于一般工業(yè)環(huán)境，但需避免油污、粉塵或腐蝕性氣體直接影響閥體性能。6912
Product Overview
The 4A220-08 5/2-way double pilot operated valve is a directional control component designed for pneumatic systems. Featuring an internally piloted structure and aluminum alloy body, it offers lightweight and corrosion-resistant properties. With a nominal diameter of PT1/4 (G1/4) and operating pressure range of 0.15~0.8MPa, it functions reliably in environments from 5~50℃. The bidirectional flow design ensures efficient air transmission, suitable for filtered air without lubrication. Threaded connections facilitate easy installation, making it ideal for automation and industrial machinery.16
Key Features
This valve utilizes pneumatic signals to shift spool positions, enabling rapid circuit switching. Its spool-type structure with precision-machined bores delivers excellent sealing and low friction, ensuring responsive performance. The dual-pilot design provides memory function, maintaining spool position without continuous pressure. Compact for space-saving setups, it supports high-frequency operations (up to 4 cycles/sec) and optional exhaust silencers for noise reduction.919
Technical Specifications
Operating with 40μm filtered dry air, the valve has an effective flow area of 16.0mm² (CV 0.89) and a minimum activation time of 0.05s. Ports include 1 inlet (P), 2 outlets (A/B), and 2 exhausts (R/S), with RC1/4 main threads and RC1/8 exhaust threads. Maximum pressure resistance is 1.2MPa, and operating temperature ranges from -5~60℃. Weighing approximately 0.225kg, its compact design suits space-constrained applications.714
Applications
Widely used in bidirectional cylinder control, pneumatic clamps, packaging machines, and automated lines, the valve excels in systems requiring stable switching and memory retention. For instance, it precisely controls double-acting cylinders via dual-pilot signals. Its pressure and temperature tolerance adapts to general industrial conditions, though direct exposure to oil, dust, or corrosive gases should be avoided.612
