Valve cap adapter and arrangement and method of removing a valve cap

Abstract:

Method of removing a valve cap threadedly engaged with a valve body includes inserting at least one coupling rod from a cap adapter through a valve cap attachment hole to couple the structures, coupling an output drive of a torque multiplier with the adapter, and exerting an input torque on the torque multiplier to rotate the adapter and valve cap, the input torque exerted on the torque multiplier being increased by the torque multiplier.
