AXONOFFMOK
This valve is specifically suitable for severe duty on-off (upstream) and for quick-acting safety applications (HIPPS, ESD). Pressure has no impact on the operating forces, and the valve can be opened against full differential pressure.
Axial flow
Streamlined flow path through the full-port expanded body avoids turbulence and prevents erosion and vibration. Process downtime and maintenance costs are reduced.
Low Pressure Loss
The capacity of the axial on-off valve is extremely high, as a result of which the pressure loss is negligible. Operating costs of pumps and compressors are reduced.
Pressure Balanced
Operating forces are independent of pressure. Valve can be opened against full differential pressure without damage to sealing. Equalisation with a bypass valve is not required.
Easy actuation
Actuation force is low and constant because of pressure-balanced trim. Small, spring-opposed actuators can be selected and gearboxes are not required.
Excelent Sealing
In the open position the main seal is protected against erosive flow. The self-energising sealing system offers reliable bi-directional and bubble-tight shut-off (class VI).
Compact design
The one-piece valve body provides 15-60% weight reduction compared with ball or gate valves. This benefit is even more attractive combined with spring-opposed actuators.
Fire Safe Design
The seals that prevent internal and external leakage are secured inside the valve body and therefore less susceptible to external heat sources. All axial on-off valves are certified fire-safe.
