Description

The Class 7 torque requirements demand a substantial 34 kNm / 25 klbft. Not all class 7 valves need the full 34kNm. Most class 7 torque tools have a very high starting torque levels, sometime very close to some upper limits of a subsea valve. This torque multiplier has a lower than normal torque multiplication so that lower torques can be easily achieved. This tool features a Class 7 output interface and a receptacle for a Class 4 torque tool. Between these two components is a 5.3 : 1 multiplication gearbox. This is an unlatched tool and would be mainly used for vertical valves.

DEPLOYMENT OPTIONS
