The movement device is used in order to verify the mechanical endurance of progressive cartridges (from closed position, the cartridge opens at first only cold water, gradually opens also hot water until full hot position).
It includes the torque motor used for endurance tests of single lever mixers. A telescopic universal joint connects the flow control under test to the torque motor. A calibrated hydraulic resistance mounted on the tap limits the flow-rate value as indicated in the standards. The test method consists in subjecting the component to a specific number of opening and closing manoeuvre; angular speed and closure torque are defined by the standards. The faucet is supplied by hot and cold water.
The software allows to control: the rotation angle, the angular speed and torque and the outlet temperature in hot position.
