Ball valves & Flow control valves for Mining & Boring
What makes MHA ZENTGRAF ball valves strong in mining and tunnel drilling?
In the beginning, there was mining. Tunnel drilling utilizes the expertise gained and matured over centuries in mining. Correspondingly, we manufacture products for both branches thus combining the greatest experience with high tech and innovation. So that the machines used withstand extreme stresses and operate safely and reliably for very long periods of time.
Cylinders can be maintained without having to switch off the hydraulic pump. In addition, safe power separation according to DIN EN 982 is guaranteed.
Several functions integrated into one block
2 ball valves/shut-off device for up to 3 locks
- Fewer potential leakage points compared with a solution using pipes
- Secured against unintentional actuation
