Jorlon™ Structurally Modified Pure PTFE Diaphragm for Control Valves and Gas Regulators

Jorlon™ Diaphragm

Jorlon™ is structurally modified pure PTFE. It is manufactured by a proprietary technique where PTFE layers are combined and formed in a unique process to reduce the creep and cold flow associated with conventionally formed solid, or laminated PTFE or Teflon.

Jorlon™ is featured in all of Steriflow's valve product lines:

• Mark 978 Control Valves
• JSHM Manual Metering Valve
• Mark 96 Pressure Regulating Valves
• Mark 95 Back Pressure Regulating Valves
• Mark 96A, 96AA, 95A, 95AA Air Loaded Regulators
• J Series Clean Gas Pressure and Back Pressure Regulating Valves

Lifetime Warranty
Jorlon™ is warranted for a lifetime of use on our Mark 95, Mark 96, Mark 96AA, Mark 95AA regulators, MK978 Series control valves, J-series regulators, and the JSHM metering valve.

Product Applications
JorlonTM has been specified in biopharm applications including WFI, clean steam (up to 100 psig), buffers, acids, cryogenic liquids, clean utility gas, biological intermediates and final process fluids.

Customer Use
Since its inception, thousands of Steriflow valves with Jorlon™ diaphragms have been installed in systems which have been validated by the FDA.

Cycle Testing
Jorlon™ has been tested on a variety of Steriflow control valves on 45 psig (3 bar) continuous steam service to over 1 million full stroke cycles. One of those valves was further tested with an additional 100 Steam and vacuum cycles without failure.

Lab Testing
Lab tests comparing Jorlon™ to 316L diaphragms have shown continued life after exceeding the SST failure cycle count by more than 100 times.

Jorlon™ Material
Jorlon™ has been used by Steriflow for over 15 years. To date, not one valve has been returned due to diaphragm failure when operating within its use parameters. Jorlon™ has been nitrogen pressure tested to over 1200 psi without failure.
