Max. Working Pressure
| Size | Pressure |
| DN50-DN250 | 10 kg/cm2 |
| DN300-DN450 | 7 kg/cm2 |
| DN500-DN600 | 4 kg/cm2 |
| DN700-DN900 | 2 kg/cm2 |

The mentioned working pressures are just valid for the pressures applied on the direction of arrow marked on the body. As the valve is designed with gate support guides, the valves are able to support a 30% of these pressures from the opposite direction without any damage on them. In these cases, the valves are not 100% water tight. To obtain total water tightness in these conditions, it is necessary to incorporate additional supports.
