NUMATICS压力开关，美国纽曼蒂克压力开关
阀套都用440c不锈钢制成，经超精密加工，达到高精度配合公差，间隙仅1μm。
由于是配对研磨抛光组件，故它们没有互换性，必须成套供应。
当气流经阀套上小孔进入，在阀芯、阀套间微小间隙中形成一空气薄膜，阀芯在阀套中自动对中。
当阀芯在这种空气轴承上运动时，像悬浮在空气分子场中一样，完全没有金属间的接触。这种空气悬浮结构带来了如下好处：
(1)芯套间的精密配合形成可靠密封。完全摒弃了蕴含许多故障因素的“○”形圈动态密封。
(3)空气轴承允许阀工作在经一定过滤得完全无润滑场合。与其它号称无油润滑元件相比(实际上装配时已涂上一层不易挥发的润滑脂)，这是一种真正意义上的无油润滑。
(4)移动阀芯启动力极小且操作力恒定，这是制造高质量直动阀的首要条件。
它可不依赖先导压力使直动阀工作在真空到21bar(甚至35bar)场合。
(5)芯套相同材质，热膨胀系数完全一样，在高温下也能确保空气轴承的存在。
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".
