Reliable bi-directional sealing

Excellent flow characteristics

A first-rate sealing
|
| The gate is supported by the valve body to withstand bi-directional pressures and the gate edge is polished in order to lower the operational force. The sealing profile is strengthened with a steel core to secure it will stay in shape and position over time. |
A straight full bore with a sealing profile in level with bore, gives minimal pressure drop since the media can pass it practically unnoticed. |
A gland box supplied with three layers of our TwinPack, which is specially developed and made for Stafsjö’s valves, secures that no media reaches the surrounding environment. |
