Valves for the chlorine industry

Universal material PTFE

Although a material employed for almost all media, PTFE is particularly resistant against chlorine and its compounds. PTFE has been the first choice for our lined valves, especially with chlorine applications, for more than three decades. Further fluoroplastics such as linings of PFA may also be employed.

In case of permeation, a greater wall thickness means everything. As low-molecular media, such as chlorine in fluoroplastics, have a tendency to permeate and as influence factors such as density, crystallinity, cross-linking etc. are extremely difficult to vary, a greater wall thickness is the most economic solution.

One cannot totally do without metal. The more than two decades of experience with valves in chlorine applications have led to diverse solutions in the choice of materials.

Special materials such as tantalum, Hastelloy, titanium, zirconium, Inconel, aluminium oxide, nickel etc. are employed in our valves as supplementary components resp. ectively as an alternative.

German Clean Air Act (TA-Luft) In order to fulfil the conditions concerning tightness to the atmosphere, our dynamic seals such as a maintenance-free cup spring live-loaded PTFE packing or the PTFE bellows in the standard version are ideally suited.

This can be shown by readily available proof resulting from helium leak tests. Special solutions, such as a double stuffing box, a reinforced bellows or a tightenable stuffing box are also here no problem due to our variety of products. Bellow seals for quarter-turn actuators, rotary motion by means of magnetic coupling or bellows in special metals such as titanium or Hastelloy may also be realised due to the well-structured modular design of our valves.

Quality check

Meeting the high quality requirements in the chemical industry the qualilty check plays an important rule in our production. Each part of our valves is carefully examined in serveral checks.

The examinations have led to optimize the linings, so that Pfeiffer valves have become a perfect example of quality on the valve sector. Each valve is tested by a special pressure test to guaranty the tightness of seat and body.
