NUMATICS壓力開關(guān)，美國紐曼蒂克壓力開關(guān)
閥套都用440c不銹鋼制成，經(jīng)超精密加工，達(dá)到高精度配合公差，間隙僅1μm。
由于是配對研磨拋光組件，故它們沒有互換性，必須成套供應(yīng)。
當(dāng)氣流經(jīng)閥套上小孔進(jìn)入，在閥芯、閥套間微小間隙中形成一空氣薄膜，閥芯在閥套中自動對中。
當(dāng)閥芯在這種空氣軸承上運動時，像懸浮在空氣分子場中一樣，完全沒有金屬間的接觸。這種空氣懸浮結(jié)構(gòu)帶來了如下好處：
(1)芯套間的精密配合形成可靠密封。完全摒棄了蘊含許多故障因素的“○”形圈動態(tài)密封。
(3)空氣軸承允許閥工作在經(jīng)一定過濾得完全無潤滑場合。與其它號稱無油潤滑元件相比(實際上裝配時已涂上一層不易揮發(fā)的潤滑脂)，這是一種真正意義上的無油潤滑。
(4)移動閥芯啟動力極小且操作力恒定，這是制造高質(zhì)量直動閥的首要條件。
它可不依賴先導(dǎo)壓力使直動閥工作在真空到21bar(甚至35bar)場合。
(5)芯套相同材質(zhì)，熱膨脹系數(shù)完全一樣，在高溫下也能確保空氣軸承的存在。
From Newark Airport: Via Route 78 to Route 24 West: Take Route 78 West (stay right) to Route 24 West. Take Route 24 Exit 2B - Florham Park (Route 510/Columbia Tpk. East). Take Route 510 East 1.8 miles to traffic light at Hanover Road (Exxon Gas Station and AAA on corners). Turn left onto Hanover Road and follow about 1/2 mile to ASCO on right hand side of road. (Main Entrance is 2nd driveway on the right, look for our "Flag Pole".)
From Kennedy or LaGuardia Airports: Proceed to George
Washington Bridge. Follow directions "VIA GEORGE WASHINGTON BRIDGE".
Via George Washington Bridge: Route 80 West to Route 287 South to Route 24 East. Take Route 24, Exit 2B - Florham Park (Route 510/Columbia Tpk. East). Take Route 510 East 1.8 miles to traffic light at Hanover Road (Exxon Gas Station and AAA on corners). Turn left onto Hanover Road and follow about 1/2 mile to ASCO on right hand side of road. (Main Entrance is 2nd driveway on the right, look for our "Flag Pole".)
Via Lincoln Tunnel: Follow signs for New Jersey Turnpike. Take the Turnpike south to Exit 14 for Route 78 West. Follow the signs for Route 78 West: this becomes Route 24 West. Follow directions "FROM NEWARK AIRPORT VIA ROUTE 24 WEST".
Via Holland Tunnel: Take New Jersey Turnpike. Follow this to Newark Airport exit. Take Route 24 West. Follow directions "FROM NEWARK AIRPORT VIA ROUTE 24 WEST".
