Wear sleeves for the S-valve are assembled on the outer bearing surface on the S-valve outlet side. Produced as thin, hardened and frquently chromed sleeves their main purpose is protection […]
S-Valve Unit
12 posts
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 […]
Connections for S-valve are the collar-type items. They are assembled on the outlet side of the S-valve unit in the “S” type or ROCK type valves. It’s basic function 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 […]
Wear bushings for the S-valve shaft (Wear bushings for shaft) are used in the bearing units of the main shaft of the S-valve. These units are constantly working in the […]
In most of the concrete pump models the shafts of the S-valve are integrated with the S-valve bodies so they cannot be exchanged separately. Nevertheless the producers such as SCHWING, […]
Bushings for wear plates (Reducing bushings for wear plate) are crucial parts of pumping unit and are assembled between a wear plate and the conveying cylinders. In many machines these […]
Compensating rings are steel supoporting rings used for the assembly purpose of the wear rings. It’s main task is to provide a continuous tightness between wear ring and wear plate. […]
Mounting collars are items used for assembly and protection of the wear ring on the S-valve. They are dedicated for firm fastening of the wear ring and provide protection against […]
Wear rings together with wear plates are the most essential wear components of the S-valve transfer system in the concrete pumps. That element is co-working in pair with a wear […]
Wear plate is the most crucial wear component inside the S-valve unit. In various shapes and versions it is used in all types of concrete pumps. It is mounted inside […]
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 – […]
