parker電磁閥的特點(diǎn) 1、外漏堵絕，內(nèi)漏易控，使用安全 內(nèi)外泄漏是危及安全的要素。其它自控閥通常將閥桿伸出，由電動(dòng)、氣動(dòng)、液動(dòng)執(zhí)行機(jī)構(gòu)控制閥芯的轉(zhuǎn)動(dòng)或移動(dòng)。這都要解決長(zhǎng)期動(dòng)作閥桿動(dòng)密封的外泄漏難題;唯有電磁閥是用電磁力作用于密封在電動(dòng)調(diào)節(jié)閥隔磁套管內(nèi)的鐵芯完成，不存在動(dòng)密封，所以外漏易堵絕。電動(dòng)閥力矩控制不易，容易產(chǎn)生內(nèi)漏，甚至拉斷閥桿頭部;電磁閥的結(jié)構(gòu)型式容易控制內(nèi)泄漏，直至降為零。所以，電磁閥使用特別安全，尤其適用于腐蝕性、有毒或高低溫的介質(zhì)。 2、系統(tǒng)簡(jiǎn)單，便接電腦，價(jià)格低廉 電磁閥本身結(jié)構(gòu)簡(jiǎn)單，價(jià)格也低，比起調(diào)節(jié)閥等其它種類執(zhí)行器易于安裝維護(hù)。更顯著的是所組成的自控系統(tǒng)簡(jiǎn)單得多，價(jià)格要低得多。由于電磁閥是開關(guān)信號(hào)控制，與工控計(jì)算機(jī)連接十分方便。在當(dāng)今電腦普及，價(jià)格大幅下降的時(shí)代，電磁閥的優(yōu)勢(shì)就更加明顯。 3、動(dòng)作快遞，功率微小，外形輕巧 電磁閥響應(yīng)時(shí)間可以短至幾個(gè)毫秒，即使是先導(dǎo)式電磁閥也可以控制在幾十毫秒內(nèi)。由于自成回路，比之其它自控閥反應(yīng)更靈敏。設(shè)計(jì)得當(dāng)?shù)碾姶砰y線圈功率消耗很低，屬節(jié)能產(chǎn)品;還可做到只需觸發(fā)動(dòng)作，自動(dòng)保持閥位，平時(shí)一點(diǎn)也不耗電。電磁閥外形尺寸小，既節(jié)省空間，又輕巧美觀。 4、調(diào)節(jié)精度受限，適用介質(zhì)受限 電磁閥通常只有開關(guān)兩種狀態(tài)，閥芯只能處于兩個(gè)極限位置，不能連續(xù)調(diào)節(jié)，所以調(diào)節(jié)精度還受到一定限制。 電磁閥對(duì)介質(zhì)潔凈度有較高要求，含顆粒狀的介質(zhì)不能適用，如屬雜質(zhì)須先濾去。另外，粘稠狀介質(zhì)不能適用，而且，特定的產(chǎn)品適用的介質(zhì)粘度范圍相對(duì)較窄。 5、型號(hào)多樣，用途廣泛 電磁閥雖有先天不足，優(yōu)點(diǎn)仍十分突出，所以就設(shè)計(jì)成多種多樣的產(chǎn)品，滿足各種不同的需求，用途極為廣泛。電磁閥技術(shù)的進(jìn)步也都是圍繞著如何克服先天不足，如何更好地發(fā)揮固有優(yōu)勢(shì)而展開。 美國(guó)PARKER電磁閥parker現(xiàn)貨總現(xiàn)貨 PHP530D-10 PHP530S-10 PHS510C-6-24V-D PHS510S-6-110V PHS510S-6-220V PHS510S-6-220V-D PHS510S-6-24V PHS520C-8-220V PHS520D-8-24V PHS520D-8-24V-L PHS520S-8-110v PHS520S-8-110V-D PHS520S-8-220V PHS520S-8-220V-D PHS520S-8-220V-DL PHS520S-8-24V PHS520S-8-24V-D PHS530C-10 PHS530D-10-220V PHS530S-10 PHS530S-10-220V PHS530S-10-220V-D PHS540D-10-24V-D-L PHS540D-10-24V-L PHS540S-10-24V-D PHS540S-15-220V PHS540S-15-24V-D PHS540S-15-24V-DL PHS540S-15-24V-DL-L PHS540S-15-24V-L PHS540S-15-L PHS541S-15-110V-L WV121S222NV-I-1S-C2 P10S-7ST020N020N P10S-7ST016N030N P10S-7ST020N030N 型號(hào) PHS320S-8 PHS320S-8-L PHS320-M2 PHS320-M3 PHS320-M4 PHS320-M5 PHS320-M6 PHS320-M8 PHS320-M10 PHS510S-6-※ PHS510S-6-※-L PHS510S-6-※-D PHS510S-6-※-D-L PHS510S-6-※-DL PHS510S-6-※-DL-L PHS510C-6-※ PHS510C-6-※-L PHS510C-6-※-D PHS510C-6-※-D-L PHS510C-6-※-DL PHS510C-6-※-DL-L PHS510P-6-※ PHS510P-6-※-L PHS510P-6-※-D PHS510P-6-※-D-L PHS510P-6-※-DL PHS510P-6-※-DL-L PHS520D-8-※ PHS520C-8-※ PHS520E-8-※ PHS520P-8-※ PHS520S-8-※-D PHS520D-8-※-D PHS520S-8 PHS520D-8 PHS520C-8 PHS520E-8 PHS520P-8 PHS530S-10-※ PHS530D-10-※ PHS510D-6-※ PHS510D-6-※-L PHS510D-6-※-D PHS510D-6-※-D-L PHS510D-6-※-DL PHS510D-6-※-DL-L PHS510E-6-※ PHS510E-6-※-L PHS510E-6-※-D PHS510E-6-※-D-L PHS510E-6-※-DL PHS510E-6-※-DL-L PHS520D-8-※-FL PHS520C-8-※-FL PHS520E-8-※-FL PHS520P-8-※-FL PHS520S-8-※-DL PHS520D-8-※-DL PHS540S-15 PHS540D-15 PHS541S-15 PHS541D-15 PHS530S-10 PHS530D-10 PHS530C-10 PHS530E-10 PHS530P-10 PHS540S-10 PHS540D-10 PHS541S-10 PHS541D-10 PHS510-M2 PHS510-M3 PHS510-M4 PHS510-M5 PHS510-M6 PHS510-M7 PHS510-M8 PHS510-M9 PHS510-M10 PHS510-M11 PHS510-M12 PHS510-M13 PHS510-M14 PHS510-M15 PHS 510-BP PHS520-M2 PHS520-M3 PHS520-M4 PHS520-M5 PHS520-M6 PHS520-M7 PHS520-M8 PHS520-M9 PHS520-M10 PHS520-M11 PHS520-M12 PHS520-M13 PHS520-M14 PHS520-M15 PHS520-BP PHS530-M2 PHS530-M3 PHS530-M4 PHS530-M5 PHS530-M6 PHS530-M7 PHS530-M8 PHS530-M9 PHS530-M10 PHS530-M11 PHS530-M12 PHS530-M13 PHS530-M14 PHS530-M15 PHS530-BP PHS520SX-8-※ PHS520DX-8-※ PHS530SX-10-※ PHS530DX-10-※ PHS520SX-8 PHS520DX-8 PHS530SX-10 PHS530DX-10 PHS520SX-8-※-FL PHS520DX-8-※-FL PHS530SX-10-※-FL PHS530DX-10-※-FL AL200-8 AL320-10 AL420-15 AR200-8 BKC320 BKC420 BKU421 GCD80*50 GDC-CA-80*70-Y GDC-CB-80*150-Y GDC-CB-80*350-Y GDC-CB-80*80-Y GDC-FH-80*60 GDCN-CA-150*160-I GDC-TM-80*120-Y NKV15N-H-1F-4K NKV20N-H-1F-4K P31CA22GEMNGLNW P33EA14ESABNNP PEC5-220V PEC5-24V PEC5-24V-D PES5 PES5 PES5L-24V PES5L-110V PES5L-220V PEC5-22EX-24V PEC5-22EX-110V PEC5-22EX-220V PEC5-24V PEC5-110V PEC5-220V PEC5-24V-FL PEC5-110V-FL PEC5-220V-FL PEC5-24V-D PEC5-110V-D PEC5-220V-D PK1A CE 20*100 PK1A CE 32*100 PK1ACE 32*110 PK1 ACE32*150 GDCCB200*150 P1D-S032MS-0650 AFR320-10-AD41 PHS520S-8-24V 486265A2 E892A2 24V50HZ(LUCIFER) AS2415-06-220 R-23 RB41ME11 71648A75750 RB41ME11 240VAC 341N3197-495900F4 341N3197-495900F4 VE13-ESC042C2 PHS520D-8-**-D,110V 341N03-496482B7 9N400B 9F400B
