Ashcroft Type 100 Series diaphragm seals are a comprehensive line of Ashcroft diaphragm seals that meet a wide variety of application or installation requirements. The top housing and diaphragm capsule are interchangeable with all Ashcroft bottom housings. A fill/bleed connection is standard, which permits filling the seal and instrument simultaneously after evacuation and allows the fill to flow into the completed unit.
A Viton O-ring, compatible with all standard fill fluids, and a Teflon back-up ring provide a seal between the diaphragm capsule and the top housing. A thin Teflon PTFE gasket between the diaphragm and bottom housing ensures a leak-tight corrosion resistant seal even at high pressure.
Applications for the Ashcroft Type 100 Series Diaphragm Seals include elevated process temperatures, corrosive services, isolation of the process for safety, suspended solids in the process, sanitary connections, minimizing process dead leg, and cleaning between batches.
