INNOVATIVEIn our company we system-atically transform ideas and concepts into high-quality products through consistent development, as well as target design and production.

PRACTICE-ORIENTED With many years of know- how and an excellent tech-nology base, we create the best for your specific project. We use the latest design, calculation and simulation methods, such as CAD 2D/3D, 3D printing, FEM, CFD.

SYSTEMATIC Our well-coordinated team methodically assembles the individual components, designed according to the modular principle, to create your functional end product or system. “Manual work” at its best.

WORLDWIDE Just like our products and systems, we are always at your side all around the world. Whether for project planning, commissioning, revisions or short term troubleshooting: Our local service technicians and trained staff always ensure your efficient production.

SMOOTHOur global commissioning service ensures a fast and smooth start up of your valve technology or plant and guarantees you both, planning and production reliability. On demand.

SKILLEDProduct training and customer workshops provide targeted, theoretical knowledge and practical assistance on function and application. You decide whether we can work for you in-house, at your site or remotely.

CERTIFIEDGenerally, we are confident that quality succeeds in the long term. Therefore, each of our products is subjected to a function and (high) pressure test before delivery. This 100 % inspection is signed by the responsible person with his personal seal of approval. “Made in Germany” – that’s what we stand for with our passion.

SUSTAINABLEAll our developments and products are designed for longevity, reusability and sustainability. This starts with the modular design and the use of recyclable materials. The majority of our products can be returned to the cycle as raw material at the end of their operating life.

COOPERATIVE Besides a great product,service is the most important pillar for a reliable and suc-cessful partnership. Through unconventional and direct contact, fast support, as well as extensive stock-keeping and regular upgrade offers, you can always keep your system up to date with us.

LONGER SERVICE LIFE. Due to the perfect synergy of a tight-sealing seat valve combined with the character of a soft-switching spool valve, the special Evertz HP²duraseal always reliably performs its service. This leads to a multiplication of the usual service life, especially in operation with heavily contaminated media. In direct comparison with hard-seated valves, but also in comparison with other soft-seated valves, the HP²duraseal demonstrates its outstanding performance.

MANUAL SHUT OFF VALVE

CONVENTIONAL DESIGNLarge space requirement. Extensive intermediate piping. Many flange connections.

3.60 m

CONVENTIONAL DESIGNSpace consuming arrangement as well as high pur-chase and storage costs due to unnecessary single component design. Multiple number of intermedi-ate piping and flange connections = more leakage points. Expensive downtimes due to the missing redundancy.


XXX15

WORST CASE FILTER 2/2 WAY VALVE PREFILLING DEVICE

LESS SPACE REQUIREMENTS. HP²compact is the synonym for multiple function and high-performance at a minimum of space. The valve housing, made of high- grade, forged stainless steel includes all interconnecting holes and thus containsthe entire logic itself. Due to the significantly minimized number of flange connections, leaking flange points and the associated production down-timesare a matter of the past. Especially in new plant construction, the greatestadvantage is obvious: The enormously reduced space requirement compared to the conventional single valve arrangement significantly reduces the requiredinfrastructure and thus the investment costs.


17

HP2COMPACTFor bundled efficiency.

HP2COMPACT DESIGN With more than 300 % of space savings, completely without piping and only two flange connection points, the HP²compact design offers multiple advantages. It is easy to maintain, reduces storage costs and meets the highest safety standards, such as a design according to PED 2014/68/EU.

50%POWER SAVING. By HP²scaledown we understand maximum performance at lowest energy usage. Our technologies allow an easy adaptation of HP²scale-down components to your existing system, as well as an optimal equipment design for new plants. In this way, we generally achieve power, water and mate-rial savings of 50 % +X, especially for long rolling campaigns, as it is common for fully continuous CSP, QSP-DUE or ESP plants.

MULTIZONAL ON/OFF OPERATIONThe minimum width of the rolled material determines the number of continuously spraying jets. Beyond the minimum width, additional jets can be switched on or off individually.

STEPLESS CONTROLYou determine the relevant zones for on/off switching, and we take care about the rest.

WEAR-RESISTANT Optimal protection of the fully encapsulated nozzles.

HIGH DURABILITYNo welds in the impactedspray area. Wear components easy to replace.

TAILOR-MADEOur ESD system is as variable as your product mix: It always adapts optimally to the width of the rolled material. Flexible in design, the ESD can also be integrated into existing rolling lines.

FULLY INTEGRATED VALVE TECHNOLOGY Compact design. No external control pipes due to purely electro hydraulic solution. Constant impact due to height adjustment.

SAFE SYSTEM BY PUMP PROTECTION. According to the system configuration our valves take the part to protect your centrifugal pumps from overheating by diverting the minimum flow.

HP²DURASEAL TECHNOLOGY Also the min-flow valves contain our HP²duraseal technology and are consequently well-prepared ready for any application.

HP2SCALEDOWNEvertz Min-Flow

VARIABLE DESIGN.Aligned to the given space conditions and the desired pressure on the low-pressure side, a length- and pressure-variable custom-made design is achieved.


XXX21

AMORTIZATION.The use of Evertz Min-Flow in the HP²scaledown design results in significant power and water savings. The amortization takes place within 12 months.

MULTISTAGE ORIFICEMaximum energy efficiency is achieved by a precise design of the minimum flow of the cen-trifugal pump. Additional to the flow-optimized CFD-design, the selection of suitable materials and coatings ensure a maximum service life.

PRECISE PRESSURE REDUCTION. Based on the most accurate calculations and simu-lations, a deviation of the minimum flow of only 5 % or less is guaranteed.
