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!

  • Up to 650 Nm continuous torque (up to 1,200 Nm with shaft-mounted gear unit) maximum 60 Umin-1 spindle speed
  • 18 VDC brushless EC-TEC motor with 4-speed metal gearbox and electronic torque cut-off
  • Drive unit 360° rotatable for ergonomically comfortable application adaptation
  • Integrated difference counter module for detecting the spindle revolutions
  • Incl. support leg and telescopic drive rod for optimum stability; optionally available with wheels for ergonomic transport
  • Incl. ¾" square tool outlet, 33 mm spare square and universal joint
  • Incl. 2 Li-Ion batteries 6.2 Ah and quick charger (AIRSTREAM technology)
  • Optional aluminium case for easy storage and safe transport
  • An extensive range of accessories for many applications, such as underfloor or overground hydrants, manhole cover locks, tapping rigs, crane winches and for emergency operation of automated drives is available as an option

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.

  • Support leg – optionally available with wheels: Ensures optimum stability during use and ergonomic transport
  • Side support with adjustable alignment (telescopic)
  • Telescopic support for the trailer hitch for particularly high-torque applications

Extensive range of accessories

Of course, our machines are customisable and expandable after purchase - that's what we stand for. Among other things, we offer the following accessories:

  • wero side gear for hard-to-reach places or to operate sliders with ascending spindle
  • wero multifunction adapter for handwheels (for 3-, 4- or 5-spoke versions in various designs)
  • wero adapter, among other things, for square caps (conical, 15 to 55 mm) and manhole cover locks (17 mm / 22 mm) and much more
  • wero telescopic output rod and joints for operating sliders in underground shaft structures
