Ashcroft Introduces Flush Flanged Diaphragm Seal

The new Ashcroft DF diaphragm seal isolates pressure instruments from harsh media. The flush flanged design reportedly eliminates the use of a costly lower housing and prevents clogging around the diaphragm. A raised face or ring joint flange mates directly to six different sized ASME flange unions. Several choices of diaphragm sizes, wetted materials and instrument connections are available.
