1.The packing system consists of a series of soft graphite sealing rings preventing leakage around the shaft. Graphite is a material which perfectly seals and resists high temperatures. Optimization of the ratio between tightness around the shaft and the actuating torque can be easily achieved by tightening or loosening the nuts holding the packing flange.

2.The split shaft significantly reduces pressure drops and provides favorable Kv (Cv) values. Lower pressure losses mean lower energy consumption, which leads to savings.

3.Top flange according to ISO 5211 enables direct mounting of manual operators and actuators. Longer neck of ABO butterfly valves results in insulation of ISO top flange, for protection of mounted actuator and meeting heating system requirements.

4.A sealing ring, ensuring tightness in the seat, forms a sandwich of stainless steel sheets layered with a soft filler of graphite. This composition is able to withstand high temperatures and ensures excellent resilience of the sealing element even during significant fluctuations of medium temperature and pressure.

5.Spirally wound stainless steel band with a soft graphite filler guarantees a perfect seal even with large temperature and pressure fluctuations inside the pipe.
