GEMÜ PPF (Pressure, Passivation, Flushing) multifunction adapter

Ideal for flushing and passivating diaphragm valves

Listen to this article

Most installation work involving piping including the installation of valves poses a risk of contamination.

Foreign matter can cause plant components such as pumps and heat exchangers to become damaged or even blocked resulting in interruptions to the process and impacting scheduling.  

Using the GEMÜ PPF (Pressure, Passivation, Flushing) multifunction adapters in 1.4435 stainless steel, the ingress of foreign particles during the installation of diaphragm valves can be prevented.

Immediately following disassembly of the actuator and diaphragm, the PPF adapter is mounted on the valve body, thereby offering protection for the seat. The sealing over the weir and to the outside is created by an EPDM seal, which is approved according to FDA and USP Class VI. The fixing method, as we know from diaphragm valves, uses four or eight screws dependant on valve size. After the multifunction adapter has been mounted on the valve body, this can be used as:

  • a weld gas exhaust during welding of the body
  • as a line protection for ingress of particles
  • passivation point for passivation media to protect the internal surface against corrosion
  • for endoscopic examination a camera can be introduced into the piping system via the GEMÜ PPF connections
  • as a tube to be connected for flushing.
  • Because the adapter utilizes a full diameter spigot, it enables optimal flow for rinsing. This can take place in both flow directions.
  • A final pressure test can be performed with GEMÜ PPF up to an operating pressure of 16 bar.

The reusable multifunction adapters have been designed for various diaphragm sizes from MG 8 to MG 100.

This enables GEMÜ to offer a safe, convenient solution to prevent contamination, flush and passivate systems and pressure test when installing diaphragm valves in piping.

The GEMÜ PPF is then simply removed after installation is complete and before sterilization of the plant and the valve diaphragm and operator fitted.
