Product data sheet The fittings are usually insulated in the systems. However, note that the flange into which the actuator is inserted is not insulated. To prevent any disturbing flow noise from being audible in quiet rooms, the pressure difference over the ball valve must not exceed 50% of the specified values. The crank handle is fixed to the AKM actuators. To operate this crank handle, the manual adjustment knob on the actuator must be pushed downwards. The actuator remains inactive until this knob is shifted into the top position again. There is also a squared end on the crank handle...

Product data sheet (1) Body of the ball valve (6) Ball, polished, chrome-plated Additional details on the definitions of pressure difference ∆p v : Maximum admissible pressure difference over the ball valve at every angle of rotation, limited by noise level and erosion. With this parameter, the ball valve is characterised as a flow element with specific hydraulic behaviour. Monitoring the cavitation and erosion along with the associated noise increases the service life and the operational capacity. ∆p max : Maximum admissible pressure difference over the ball valve at which the actuator can...
