Gear Operator |
|
|
|
The introduction of the Dantorque gear operator enables Dantorque to
provide a one stop-service to industry with the addition of a manual /
ROV gear operator.
Available in sizes with max. output
torque of 6000 Nm (53100 in lb) up to 305000 Nm (2699250 in lb) or to
customer requirements.

Gear Operator |
| |
 |
In developments with a mix
of hydraulic and mechanically operated ball valves this facility
simplifies one of the key interfaces in providing interchangeability
between mechanical and hydraulically operated valves.
The concept has been developed to provide a
subsea compatible unit which is compact in size and flexible in design
to suit diver / ROV operation.
|
| |
|
|
Type MP |
|
|
Manual Gear Operator with
input shaft perpendicular to valve stem and equipped with hand wheel for
diver operation. Requires an input torque of 45 Nm (400 in lbs). |
|
Type RK |
|
 |
For operation by diver or ROV held torque tool. Gear operator with input
shaft co-axial to the valve stem and equipped with torque tool
receptacle to ISO 13628-8 (formerly API 17H). Requires and input torque
of max. 1130 Nm (10000 in lb). |
