Walform Seals

What are Walform Seals?

Walform Seals are high-quality sealing solutions for hydraulic applications. They consist of three parts: a fitting, a nut, and a Walform-WD-Ring. This special design ensures a positive fit and an elastomeric seal, resulting in an extremely reliable and leak-free connection. The importance of leak-free connections in hydraulic systems cannot be overstated, as any leakage can lead to performance loss, environmental damage, and increased maintenance costs. Eaton Walterscheid Walform Seals offer a durable solution that is easy to install, requires low tightening torques, and is fully interchangeable with DIN2353 standards, making them an ideal choice for various industrial applications.

Components of Walform Seals

Walform Seals consist of three essential components: a fitting, a nut, and a Walform-WD-Ring. The fitting forms the base of the connection, while the nut ensures a secure fastening. The Walform WD-Ring, a unique elastomeric seal, provides an additional layer of leak protection. When these components are assembled, the nut applies the correct pressure on the WD-Ring, which perfectly adapts to the contours of the fitting. This results in a positive fit and a reliable, leak-free seal. This collaboration of components minimizes the number of potential leakage points, creating an extremely reliable connection essential for hydraulic system performance.

Advantages of Walform Seals

Walform Seals offer very high reliability thanks to the positive fit and elastomeric seal, resulting in a leak-free connection. They are easy and quick to install, with low tightening torques and a short assembly path, reducing installation time and costs. Additionally, these elastomeric seals are fully interchangeable with DIN2353 standards, enhancing their versatility and ease of use. The quality of these seals is consistent and reproducible, ensuring reliable performance in various applications. These advantages make Walform Seals an excellent choice for hydraulic systems where reliability and efficiency are crucial.

Technical Highlights of Walform Seals

Walform Seals offer a double sealing effect thanks to a soft and metallic seal in the 24° cone, providing extra leak protection. The patented nose guarantees absolute reliability even under extreme conditions. The symmetrical shape prevents errors during handling and installation. Block assembly offers multiple advantages: it is not affected by tolerance variations, provides a noticeable increase in torque, requires lower tightening torques, and allows for easy repeated assembly. These technical highlights, developed by Eaton Walterscheid, make Walform Seals ideal for applications requiring reliability and precision, contributing to efficient and reliable hydraulic system operation.

Test Program and Certification

Walform Seals undergo an extensive test program to ensure their reliability. This includes repeated assembly tests, leakage tests, high-pressure gas tests, burst tests, vacuum tests, and pull-out tests. They are also subjected to cyclic endurance tests with vibrations, shock tests up to 700 g-forces, and fire endurance tests. These rigorous tests ensure their performance in various industrial applications, such as the automotive industry, shipbuilding, and industrial machinery. Moreover, Walform Seals are certified by leading certification bodies such as Lloyds, DNV, ABS, Germanischer Lloyd, and RINA, confirming their compliance with international standards and suitability for critical applications.

Applications of Walform Seals

Eaton's Walform Seals are used in various industries due to their reliability and efficiency. They are applied in the automotive industry for hydraulic lines and brake systems, in shipbuilding for leak-free connections in fuel and cooling systems, and in industrial machines for reliable hydraulic and pneumatic connections. In the automotive industry, Walform Seals ensure safe and leak-free hydraulic systems, while in shipbuilding, they contribute to the integrity of critical systems. Industrial machines benefit from their easy installation and high-pressure resistance, reducing maintenance costs and extending equipment lifespan. This versatility makes these elastomeric seals an indispensable solution in many technical applications.
