Higher Pressures for PTFE Regulators

PTFE Regulators for High Pressure

  • PTFE bpr with Kalrez o-rings

To satisfy customer demand, Equilibar has now expanded its 100% PTFE Teflon regulator options to higher pressure ratings. Using 1/8″ and 1/16″ PTFE tubing, these regulators can now be rated to 250 psig and 500 psig (respectively). These units incorporate Teflon PTFE/Glass diaphragms and Kalrez FFKM wetted o-rings.

The LF1 back pressure regulator featured in the photograph contains flat-bottom port with 1/4-28 threads. To improve the lifetime of the ports, the threads on the PTFE regulators body are reinforced with stainless SS316 Heli-Coil inserts.

The “cone and gripper” system shown is available from Cole Parmer and features a Tefzel fluoropolymer cone (wetted) and a glass-filled polypropylene gripper (non-wetted). This particular unit is intended for 1/8″ tubing and is rated for 250 psig.

Meeting the challenges of vacuum holding applications

Vacuum technology is commonly used to hold objects in place for processing or positioning. Vacuum table, vacuum conveyor and vacuum pick-and-place operations are examples of this type of application. In most vacuum holding applications, flow rate and pressure vary significantly during start-up and when disruptions occur in the manufacturing process. While some vacuum applications are Read More
