D74 2-PIECE INDUSTRIAL SEAL
DESCRIPTION & FEATURES
- Two piece construction and designed to withstand even the most severe process applications
- “Continuous use” seals – backing plate will prevent diaphragm from rupturing if pressure sensing instrument fails. Pressure will be held until instrument is replaced
- Diaphragm is separable for servicing and is available with a 1/4” NPT flushing connection for removing any material which may clog the process connection
- Standard diaphragm is constructed of AISI 316 stainless steel and welded to the upper chamber of the seal
- ASME B40.100 compliant
- 5 year warranty
APPLICATIONS
Where the media is low in pressure and the process fluid is corrosive or viscous and would clog instrument internals/solidify within the pressure gauge, switch or transmitter -
