Efficient media control with stainless steel valve nodes – your advantages
Hygiene from the very beginning
Our valve manifolds are welded to a high standard, and their design is tested for ease of installation. CIP and SIP cleaning processes run smoothly, and all product-contact surfaces are easily cleanable. This ensures maximum food safety, reduces the risk of contamination, and minimizes your cleaning effort. We pay close attention to hygienic design during the installation phase to guarantee minimal downtime.
Compact design
Maximum functionality in a minimal footprint – the modular design of the valve bodies shortens pipe runs, saves space, and, thanks to prefabrication, enables quick on-site installation. This means lower conversion costs, easier retrofitting, and greater flexibility for future expansions. We would be happy to advise you on the valve manifold layout with regard to accessibility and ease of maintenance.
Quality that is documented
From the material to the final weld, every step is inspected, fully documented, and supported by material certificates. If agreed upon in advance, you will receive complete, auditable documentation suitable for internal quality assurance, customer acceptance testing, and regulatory inspections.
That's why companies trust STW
Because we in Pipe Installation. We offer more than just welding and installation services: Material management, assembly and documentation from a single source, put on state-of-the-art manufacturing technologies such as orbital welding, ensure quality through certified testing competence and guarantee with complete documentation Maximum auditability. Whether food, beverages, pharmaceuticals or energy – our customers know they can rely on us. Quality, adherence to deadlines and future-proofing Received. No matter what application you are planning for your systems and pipes, STW is your partner.

Technical features & equipment options of our valve nodes
Durable materials
We use high-quality stainless steel (e.g., 1.4301 / 1.4404), which remains permanently corrosion-resistant even under high temperatures, aggressive media, or in humid environments. This means: Less maintenance, longer lifespan, lower operating costs.
Media diversity
Whether liquids or complex process media – our valve manifolds are designed for reliable operation in food, beverage, pharmaceutical, and chemical processes. You benefit from stable processes, high product quality, and safe media separation.
Flexible valve combinations
Diaphragm, double-seat, or shut-off valves – we combine precisely the designs your processes require, according to your specifications and in consultation with your engineering team. The result: optimal control, easy expandability and less building space required.
Perfect integration
Product lines, tanks, control heads, mixing units, or distributors are connected with a precise fit. Thus to reduce we Cable routes minimize energy losses and provide for one smooth connection with your existing system.
Well-thought-out construction
Our valve manifolds are manufactured to be stress-free and low-distortion, modularly expandable, and can be equipped with maintenance features such as access platforms or lifting equipment brackets upon request. This means: Faster interventions, less downtime and Long-term stable operating results.

Process of our collaboration
1. Analysis
You send us your drawing or flow diagram – we check the feasibility, clarify all specifications, and coordinate on materials, media, and installation space. If necessary, we conduct an on-site inspection. Even at this early stage, we create your project folder, collect documents, and ensure a structured database – so that future decisions are transparently documented.
2. Strategy
We will create a detailed offer clearly describing all functions, components, and materials. If adjustments are necessary, we will implement them in revision-proof versions until you give final approval. This ensures complete transparency regarding costs, delivery time, and technical implementation.
3. Implementation
Once approved, production begins in our own workshop. Our certified welders and testing experts use state-of-the-art processes such as orbital welding to create precise, hygienic, and durable joints. A project manager coordinates the entire process – from material procurement to final assembly on site – and ensures that deadlines are met.
4. support
After successful installation, we will provide you with complete documentation (up to 100% documentation if required): weld seam certificates, material certificates, and test reports. Upon request, we also offer optimizations or expansions – ensuring your system remains at its peak performance for years to come.
