Handheld Valve Operators E.H. Wachs powered handheld valve operators are built for quick operation and exercising of non rising (Pow-R-Drive II) and rising stem valves (RS-2). Available in pneumatic, hydraulic and electric drive, the P-2 and RS-2 are powerful and highly portable for quick and safe operation of most valves, handwheel valves and post indicator valves (PIV). E.H. Wachs handheld operators are designed for safety, including safety of the operator and safety of your operation. These powerful handhelds spares the arm and back injuries associated with manually attempting to turn large, stubborn or frozen industrial valves. Safety takes on a new meaning when valves have to be opened or closed quickly in critical situations, as Wachs valve turners operate much faster than even the strongest individual.
