2 How to choose the valve group for Press Brake?

When choosing a Press Brake valve group, you must choose the Deli brand. The Chinese brand has not yet reached the standard in terms of positioning contr When choosing a bending machine valve group, you must choose the Deli brand. The Chinese brand has not yet reached the standard in terms of positioning control accuracy. The German brands Rexroth and HAWE have their own characteristics, which can be considered from the following aspects:ol accuracy. The German brands Rexroth and Hawe have their own characteristics, which can be considered from the following aspects:

Performance

• Rexroth: It is a leading company in the global hydraulic industry, with advanced technology and rich product types to meet the needs of different scenarios. Its valve group has the advantages of high pressure resistance, low internal leakage, and strong interchangeability, and is suitable for demanding industrial environments. In terms of control accuracy, with advanced control algorithms and high-precision sensors, it can achieve precise flow and pressure control to ensure high-precision processing of the bending machine.
• HAWE: It is characterized by an all-steel structure of the valve body, high pressure (up to 700bar), small size, long life, no leakage, integration, and good reliability. Its valve group has stable performance under high pressure environment and can adapt to harsh working conditions. In terms of flow control, the design of the HAWE valve group can achieve relatively precise flow regulation to meet the flow requirements of the bending machine at different working stages.

Quality and reliability

• Rexroth: With a strict quality control system, its products have been rigorously tested and inspected, and have proven their reliability in millions of hours of operation. Its brand has a good reputation and is widely used in major projects around the world, such as the Shanghai World Expo and the National Grand Theater.
• HAWE: Passed ISO9001 quality certification and has the most advanced processing and testing equipment in the industry in Europe. Its products have exquisite manufacturing technology and reliable quality, and are widely used in the fields of mobile hydraulics and industrial hydraulics.

Installation and maintenance

• Rexroth: The new hydraulic valve series adopts ISO 7368 standard mounting holes, applies modular design concepts to hydraulic systems, increases flexibility for future modifications, and replaces the logic cover to adapt the function to new needs. Its products have a large market share, a complete after-sales service network, and maintenance personnel can easily obtain relevant technical information and spare parts, and the maintenance cost is relatively low.
• HAWE: The product structure is compact and the installation space requirement is relatively small, which is convenient for installation in the limited space of the bending machine. The maintenance of its products is also relatively simple. Due to the all-steel structure of the valve body, it is not easy to have corrosion and other problems, which reduces the maintenance workload. However, HAWE's domestic market share is relatively small compared to Rexroth, and the after-sales service network in some areas may not be perfect, and the supply of spare parts may not be as timely as Rexroth.

Price

• Rexroth: As a leading brand in the industry, its product prices are usually higher. However, its products have excellent performance and reliable quality. Considering its service life and maintenance cost, it is still cost-effective for large enterprises or users with high requirements for equipment performance.
• HAWE: The price is relatively moderate compared to Rexroth, which can provide users with better performance and quality. At the same time, it has certain advantages in price. It is a good choice for users with limited budgets but who want to obtain high-performance valve groups.

In summary, if the enterprise focuses on brand awareness, technological advancement, control accuracy and the perfection of the after-sales service network, Rexroth is a better choice; if the enterprise has high requirements for the product's high pressure resistance and compact structure, and hopes that the price is relatively moderate, HAWE has more advantages. In addition, users can also refer to other users' experience and evaluation according to actual needs and budget to make a more appropriate decision.
