Description
- For general information concerning the operation of a Hydrobloc control valve, please consult our general manual ( series K ).
- Extensive range including two different designs:
– XG design:
– Large flow capacity
– Low head loss
– Watertight at zero flow rate
– XGS design:
– Particularly suitable to high differential pressures.
– Better cavitation resistance
– Watertight at zero flow rate.
