The levers - also called the grips - are the basic tool enabling the control of ball valves. Depending on nominal diameter of the valve and the nominal pressure, a lever of an appropriate length and construction is used, which allows to control the ball valve by rotating the stem by 90 degrees. BROEN recommends the use of a BROEN planetary gear, when the use of levers is not possible due to a high opening torque of the valve.
Planetary gears support the control of the fittings, when the high opening torque of the valve prevents the use of a lever.
The gear is used for manual control of the fittings between the terminal positions OPEN - CLOSED (90º rotation angle), substantially reducing the force required for its operation. The terminal positions are enforced by the bumpers located during the installation of the gear on the fitting and then protected against the regulation. The PO-27 gear is a non-self-locking two-stage planetary gear using the cylindrical gears lubricated with grease and equipped with bearings on sleeves with Teflon coat, which ensures the high mechanical efficiency. The planetary gears can be also installed on various length columns enabling the control of the fittings installed in underground piping systems.
The stem extension is the extension of the stem allowing in this way the control of a valve installed in an underground systems or in places requiring the control from a strictly set height. In addition to the standard height stem extensions, BROEN also recommends the telescope stem extensions of a regulated height and stem extensions made to individual orders of the customer according to the predefined parameters. A lever, planetary gear or any type of the drive (electric, pneumatic, hydraulic etc.) installed at the top of the stem extensions could be the element enabling the control of the valve.
