In the textile industry, dyeing and finishing are processes where precision is a technical necessity. A small deviation in bath temperature or in steam accuracy can result in colour variations or defects in the feel of the fabric. At Comeval Valve Systems we offer Diaval – Comeval solutions to avoid those errors.
With valves such as the ZEDOX HEXO® we guarantee thermal stability and fluid management that delivers the highest quality in the finish of every fabric, ensuring that each finishing stage meets the most demanding quality standards on the market
This solution transforms your plant’s performance through these key points:
1. Thermal stability for a uniform colour
The dyeing process requires rigorous control of the temperature curve. The ZEDOX HEXO® valve allows flow to be optimised by up to 35% thanks to its single disc design. By reducing turbulence and pressure losses, the steam supply to the heat exchanger is much more stable, ensuring that the bath heats up progressively and uniformly. This avoids “heat shocks” that could fix the colour unevenly.
2. Fast response and no leakage at all
In textile finishing, opening and closing cycles must be precise so as not to waste energy or chemicals. The double compensation principle of this valve reduces the contact angle and minimises friction from the moment it opens. This makes it easier for the actuators to respond with millimetric precision. In addition, its absolute tightness ensures that, when closed, no fluid passes through that could alter the chemistry of the process.
3. Reduced vibration for guaranteed process stability
Vibration in the pipework often causes incorrect sensor readings. The optimised contour of the HEXO® disc drastically reduces this downstream vibration, achieving a more laminar flow. This allows the plant’s measuring instruments to deliver real, stable data, making it easier for the control system to adjust the parameters with surgical precision in every batch.
4. Complete versatility with water, steam and gas
Standardisation is essential for efficient maintenance. The ZEDOX HEXO® valve is designed to work with liquids, gases and vapours in a range from -40 °C to +260 °C. This versatility makes it possible to unify solutions across the whole production line, from washing water control to high pressure steam, simplifying spare parts management and guaranteeing exact results at every stage.
At Comeval Valve Systems we know that the excellence of a fabric begins with the control of its processes. Thanks to Diaval – Comeval engineering we offer you the ideal solutions to maximise your operational performance.
