Cordless slide valve wrench GMS 650 Z
With the battery-operated slide valve wrench GMS 650 Z you can even move large and stiff slides. The newly developed WEROWAVE technology with its construction of high-quality components guarantees a long service life. In addition, the two included Li-Ion battery packs with AIRSTREAM technology ensure fast charging and thus maximum operational readiness in everyday working life.
With its 650 Nm continuous torque, the GMS 650 Z is your professional partner in the gas, water, sewage and industrial sectors. Our extensive range of accessories, such as the wero telescopic output rod for the ergonomic operation of underfloor sliders, the telescopic support for the trailer hitch in particularly high-torque applications or the many separately available adapters make the GMS 650 Z a multi-talent and the first choice for all users, with a total weight of only 5.7 kg!
Slide valve wrench WMS 800 Z
The AC-powered WMS 800 Z slide valve wrench offers reserves that leave little work to be done. The gear unit with the newly developed WEROWAVE technology in conjunction with a professional industrial drive (1,300 W) forms an extremely powerful device. Robust and proven drive technology is paired with state-of-the-art control electronics for adjustable speed and torque limitation. And if the torque of 800 Nm is not enough for you, the power can be increased to up to 1,200 Nm with an optional shaft-mounted gear unit. If required, the shaft-mounted gear unit can be easily mounted on and removed from the GMS 650 Z and WMS 800 Z slide valve wrenches. We offer our machines of the WMS E series with torques of up to 3,500 Nm as custom-made products that can also be used as screwing machines.
