S-VALVE units in the concrete pump is the heart of the entire pumping unit. It is always integrated with the conveying cylinders. Connected to the hopper with agitator. Regardless of its design it’s job is to separate inside the hopper a concrete flow on pressure side from the suction side. Seen from the design-structure: the S-valve unit is a type of gate valve switching the concrete flow from the pumping cylinder to the hopper-outlet by shifting between the two parallel conveying cylinders.
What types of valves are applied?
The most common main shifting-valve in a concrete pump is the s-valve model. It is used by PUTZMEISTER, CIFA, SERMAC, EVERDIGM, JUN JIN, WAITZINGER, KLEIN, COIME, SEBHSA. Second type of the shifting-valve is the ROCK-type valve, which functionally is similar to S-valve principle. Third easily recognizable shifting-valve is the trunk – so called “elephant” pump – a “C” shaped valve designed and used in the BRF Putzmeister machines.
Pressure rings (tension-sealing rings) are elastomeric, flexible rings assembled on wear rings. Most often these items are manufactured out of natural rubber, poliurethane. The main task of these rings is […]
Bearing connection of the S-valve form the integrated unit with the S-valve due to it’s premanent connection with the S-valve itself. Bearing connections are designed as sleeves with cylindrical bearing […]
S-Valves, also called shifting elements, can be supplied in many different variants differentiated by pump-model. The most common type are the s-valve, which are commonly used by German producers – […]
