Tire Manufacturing
Production plants for tires place extremely high demands on valves. Tire curing presses work at high pressures of steam, water, and nitrogen, as well as at high temperatures. In addition, the very short processing cycles require extremely robust valves for very high cycles, so that good operating efficiency is achieved with the service live being as long as possible.

Especially two valves of Schubert & Salzer Control Systems have proven particularly suitable for these demanding operating conditions.

Angle seat valve 7010 in stainless steel, distinguishes itself by high Cv values at a very compact construction, a variety of possible connections, and very easy maintenance. High-temperature versions, developed especially for tire curing presses, ensure a high degree of tightness and long service life even in hot-water applications up to 220° C. The special advantage of 7010 angle seat valves is the high wear resistance. This is very important under the critical conditions of vulcanisation with deposits and corrosion in the pipeline. The 7010 valves from Schubert & Salzer operate at the same place without problems for 2- 3 years without leakage.

The unique sliding gate valve of Schubert & Salzer Control Systems has proven itself as the superior control valve solution in tire curing presses all over the world. The GS valve product line controls liquid, steam, and gaseous media precisely, quickly and economically.

In curing installations, the following properties of sliding gate control valves have proven extremely advantageous:

- very long service lives, because the service life exceeds that of globe control
  valves by up to seven times,
- for every operating requirement in the system, the valve can be optimised
  with a corresponding Kvs value, which requires merely the simple
  replacement of the fixed disk,
- the optimised Kvs value significantly extends the service life of the valve,
- the high control accuracy of the sliding gate valve allows a shortening of the
  press cycles resulting in increased productivity,
- simple and quick maintenance of the valve by replacing the easily accessible
  disk pair.

Valves of Schubert & Salzer Control Systems are not only used in tire curing presses, but of course also in the central supply of steam or nitrogen, at the mixer (air regulation for further transport), air conditioning, etc.
