High accuracy torque multiplier for wet valve actuation

Norbar Torque tools has developed an innovative torque multiplier for the subsea tools market. Designed as an adapter to allow API 17D Class 4 intervention torque tools to generate the torque required to handle Class 7 applications, the new torque multiplier delivers a higher level of accuracy than alternative solutions, and increased flexibility in use through its added-value features and its ability to be configured in two standard lengths.

 
The gear unit has been designed as an adapter for torque tools used on subsea Christmas trees – the assemblies of control valves, gauges and chokes that control oil and gas flow at a well head. Installed on the ocean floor at depths of up to 3000m, these ‘wet trees’ provide the ultimate challenge for the torque tools designed to actuate the various valves.
