Actuators Upon request, ball valves VB-70 can be delivered with pneumatic actuators, either double acting or spring return. The actuators can be worked by standarised or bottled air.
Electrical actuators of 24V, 115V and 230V can also be assembled.
Tests
100% tested in accordance to API STANDARD 598. Each valve is tested to check the leakage in the seats and packing. Upon request, the corresponding materials and test certificates can be delivered with the valve.
Maintenance Our VB-70 valves are designed to be operated in a fully open or fully closed position.
Valves with long no-working period may have a harder initial operating torque. |
