D70 Diaphragm Seal

Brand: Winters Instruments

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 1/8” NPT or 1/4” NPT flushing connection for removing any material which may clog the process connection
  • Standard diaphragm is constructed of AISI 316L stainless steel and welded to the upper chamber of the seal for pressures 30 psi (200 kPa) and above; optional Viton® diaphragm available for ranges from 30” Hg Vacuum (-100 kPa) up to 100 psi (690 kPa). Others diaphragms available
  • FKM is highly recommended for applications less than 10 psi
  • ASME B40.100 compliant
  • RoHS compliant
  • CRN registered (all 316 SS only)
  • 5 year warranty
