Hydrogen flush flanged diaphragm seal DF

The Ashcroft DF flush flanged diaphragm seal uses a diaphragm welded directly to the assembly flange.

This eliminates much of the cost associated with bulky lower housings made from exotic and expensive wetted materials.

The flush-mounted diaphragm prevents clogging and is available in a full range of metallic and coated materials.

There is also flushing ring option for flush flanged diaphragm seals.

Flushing ring is available for various ASME B16.5 flange sizes.

Key features

Flush mounted diaphragm seal prevents clogging of process media

Flush design minimizes the use of expensive specialty wetted materials

Continuous-duty construction

Available with a wide range of wetted materials

Available with optional Flushing Ring

Compact design eliminates need for lower housing

Protects process and instrumentation with materials to fit your application

The flushing ring provides a process flushing option for flush flanged diaphragm seals

Flushing ring can be used to flush, sample, or vent process when used with isolating valves

Dual ½ NPT flushing ports for flush (DF) diaphragm seals

Flushing ring is machined from bar stock

Flushing ring is available for various ASME B16.5 flange sizes

Materials

For wetted components:

Diaphragm: 316L SS, Monel® 400, Tantalum, Hastelloy®C-276, Halar® coated 316L SS, Gold plated 316 SS, Teflon coated 316SSL, Hastelloy C-276 Teflon coated, Inconel 625, Inconel 825, Teflon coated Tantalum, Duplex 2205

For non-wetted components:
