RBU RSS gate valves - your customized solution for free-flowing materials
In plant engineering, gate valves are used to shut off free-flowing substances, among other things. They are used in silos or conveyor systems, where they open or close the cross-section in vertical pipes.
Our RSS gate valves are characterized by their robust design and corrosion resistance and are able to withstand operating temperatures of up to 800 °C and a maximum pressure of up to 500 mbar without any problems. They are therefore particularly suitable for applications in the building materials or waste disposal industry where free-flowing material needs to be transported or shut off in a controlled manner.
As with all RBU products, the RSS gate valve can be configured exactly to your operating conditions. We offer sizes between DN 100 and DN 2000 as well as round and square versions.

Drive variants of our RSS gate valves
We offer our RSS gate valve in various drive options, which can be selected depending on the application and requirements of your systems.
Power take-off drive
The rack and pinion drive is a manual control method that is particularly low-maintenance. They are a practical solution that is suitable for systems where neither electrical nor pneumatic energy sources are required.
Spindle drive
The spindle drive can be operated electrically or pneumatically and is usually used for automated process requirements. It enables precise control, which is necessary for regulating an exact material flow.
Pneumatic cylinder
Pneumatic cylinders are the ideal solution for fast switching operations. They ensure a high level of operational safety and are particularly suitable for high-performance systems with frequent switching cycles. They are also a reliable alternative in potentially explosive areas, as no electrical control is required.
Our gate valves in use
RBU's RSS gate valves are used by our customers who need to ensure precise control of free-flowing materials under challenging operating conditions.
- In raw material processing our gate valves ensure reliable and controlled shut-off of bulk material flows to guarantee a smooth material flow.
- Also in mechanical and plant engineering Our gate valves are designed for use in systems with temperatures of up to 800 °C and are used, for example in the metal and cement industry where they guarantee reliable operation even under thermal stress.
- For particularly demanding applications we offer our gate valves with an optional inlet funnel made of wear-resistant material. This extends the service life of the system and reduces maintenance costs.
