Quality and Handling

For decades, these ball valves have proven their outstanding quality in continuous operation for our customers worldwide. Specifically designed for manual operation, the shaft seals with adjustable gland nuts maintain a reliable seal even under strongly eccentric forces.

Face-to-face lengths

The valves of this product series are not manufactured according to standard face-to-face dimensions but are considerably shorter. Therefore, these ball valves are ideal for confined installation spaces where a cost-effective yet high-quality ball valve is required.

Inline Service

Due to the design, replacing seals or spare parts while the valve remains installed is straightforward. Only one bolt needs to be loosened while the remaining bolts are removed.

This allows the center section with all wear parts to be easily swung out. During reassembly, the body and ball seals simply need to be positioned carefully before the center section is swung back into place. Tighten the bolts – and the valve is ready for operation again.
