Actuated Ball Valves
DAFRAM valves are suitable for manual operation by wrench or by gear when the force required at the wrench rim exceeds 300 N. Locking facility (API6D, 6.11) is available for both wrench and gear operators.
According to customer requirements DAFRAM can supply cast iron, steel or stainless gears suitable for different service conditions such as:
- Low temperature (down to -60° C)
- Fire Safe
- Buried service
When valves are required with power operation, DAFRAM is able to assemble the valves with specific actuators as per customer requirements (i.e. Electric, Peumatic, Hydraulic or Gas over oil actuators), to perform the proper functional tests and to issue the related torque records and certificates.
