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 cast iron, steel or stainless gears can be supplied suitable for different service conditions such as:

1. Low temperature (-60° C to +100° C)
2. Waterproof
3. Marine
4. Fire Safe
5. Buried service

When valves are required with power operation, Dafram can assemble the valves with specific actuators as per customer requirements (i.e. Electric, Peumatic, Hydraulic or Gas over oil actuators), and will perform the proper functional tests and issue the related torque records and certificates.
