With over 15 years of experience, Valland is a distinguished OEM in manufacturing on/off valves for the oil, gas, and energy Industries. Their tailor-made Ball, Gate, and Check Valves are recognized for impeccable quality, reflected by certifications such as API 6A, API 6D, and API 6DSS. Valland’s dedication to innovation is evident as they transitioned to incorporate an in-house 3D printing department in 2020, emphasizing R&D and Additive Manufacturing for severe service applications in compliance with API20T and API20S standards.
One of the noteworthy components produced using additive manufacturing is the Hydraulic Manifold for the valve’s actuator. Traditional manufacturing methods, specifically milling, posed challenges in achieving internal connections.
Through Nikon SLM technology, Valland managed to optimize the manifold, striking a balance between performance, customization, and topological advancement.
Traditional limitations replaced with Nikon SLM technology innovations
Faced with the challenges of traditional manufacturing methods, Valland embarked on redesigning the manifold component. The objectives were clear: maximize stiffness, reduce weight, optimize topology, cut down on production lead time, and ensure component customization.
Nikon SLM technology provided the tools and flexibility needed. The freedom of design granted by additive manufacturing enabled Valland to customize the component and achieve topological optimization.
With generative design, using a maximum stress lower than 60% of the material yield strength and a maximum mass of 12 kg, it has been possible to achieve a final mass for the additive manufacturing part of 9,8 kg. Considering that the traditional part was 25,6 kg, it has been possible to reduce the weight by 61,7%.
Moreover, considering the whole supply chain, with the traditional methods, it would have been necessary a lead time of 2-3 months to receive the forged material to be machined. Using additive manufacturing, it is possible to produce 5 parts in 4 days and, considering 2 weeks for the post-processing, it is possible to have them ready in 3 weeks.
Selective laser melting
Selective laser melting (SLM) builds up material layer by layer. In the SLM process, a layer of metal powder is spread onto a substrate plate, followed by selective laser melting to produce the desired part. This method ensures complete melting and bonding between layers, yielding dense and durable metal components. Valland capitalized on the SLM 500‘s capabilities to produce the Hydraulic Manifold, a crucial component for control panels in valve actuators within the oil & gas and hydrogen industries.
Collaborating with Nikon SLM Solutions, especially Senior Application Engineer Andrea Penna, was instrumental in ensuring the success of this project. The blend of Valland’s industry-specific knowledge with Nikon SLM’s technical expertise birthed an efficient and effective component, which promises advancements in lead time supply chain management and weight savings.
