Custom Valves and Custom Valve Solutions

A custom valve becomes a viable option when available standard designs cannot adequately meet key requirements. This may pertain, for example, to material selection, actuation, valve function, media compatibility, or structural integration. However, this does not necessarily mean a completely new design is required. We first examine whether an existing valve design can be adapted. Only when this approach is technically insufficient does a more extensive custom solution become relevant.

For the technical evaluation, information regarding the application is particularly important. This includes the medium being used, the operating conditions, the required valve function, and design specifications. Requirements regarding materials, actuation, or installation conditions can also play an important role. The more specific this information is, the more precisely we can assess which existing valve technology is a viable starting point and where adjustments are necessary.

No. This is precisely where one of the advantages of our modular system lies. Depending on the application, we can draw on existing valve designs and components to develop a customer-specific configuration. Therefore, a completely new design is not required for every deviation from the standard. However, if the technical requirements cannot be reasonably met using existing designs, it may be necessary to develop a more advanced custom valve.

Our existing product portfolio includes various valve technologies. These include plastic valves, metal valves, coaxial valves, control valves, and PriWO refrigeration valves, as well as other fittings. Which product group provides the right technical foundation for a customized solution depends on the specific application. That is why we do not base our decision solely on a general product designation, but first consider the function, medium, and operating conditions.

That depends on the specific valve group and application. Our product portfolio includes, among other materials, various types of stainless steel and brass, as well as plastics such as PVC, PTFE, PVDF, and PP. The selection of a material should be based on the actual operating conditions and the medium being used. Not every material is suitable for every medium and every valve design. Therefore, the choice of material is part of the technical design process and should not be left until the final product selection.

Our current product portfolio includes valves for a variety of aggressive and corrosive media. In such applications in particular, the materials in contact with the medium and the specific design principle must be carefully considered. Depending on the application, for example, plastic solutions made of PTFE, PVDF, PVC, or PP—or suitable metallic materials—may be appropriate. However, the specific suitability can only be assessed based on the medium and the operating conditions.

Yes. Machine and plant manufacturers, in particular, often require specific valve variants not just once, but on a recurring basis for their own products. In this case, in addition to the technical design, future supply also plays a role. RSG has its own manufacturing facilities, warehousing, and ERP-supported processes. In addition, customized logistics models and framework agreements can be arranged. This allows a customer-specific valve solution to be integrated into a recurring procurement process.

In practice, these terms are often used interchangeably. However, we see an important difference in the potential scope of development. A custom valve can be created simply by specifically adapting or configuring an existing valve solution. A special-purpose valve goes a step further when the application requirements cannot be adequately met with existing variants and components. A technical evaluation of the application determines which approach makes sense.

The installation situation can be a key component of a customer-specific project. In mechanical engineering in particular, components often have only a defined installation space available. For this reason, design integration should be considered as early as possible. Our work with 3D CAD supports technical design and coordination. Whether and to what extent a specific adaptation is possible depends on the specific valve type and other operational requirements.

A modular system provides a technical foundation that bridges the gap between an unmodified standard product and a completely new design. Existing valve designs and components can be combined or adapted to meet new requirements. This makes it possible to first assess how much custom design is actually necessary. This is particularly beneficial for the customer because the technical solution can build on existing valve expertise, rather than starting from scratch for every project.
