Main functions
The performance test bench for mixing and mixing valves is a test bench designed to measure the performance of valves and fittings using measuring instruments.
The station is used to test the mechanical strength and hydraulic characteristics of mechanical and thermostatic mixing and mixing valves.
This test bench can be used by :
- R&D for design ;
- prodcution for routine tests ;
- laboratories for characterization, qualification and verification of compliance with standards .
Our valve test benches are designed on a modular basis and can be equipped with a software allowing to automate testing to control measuring instruments, perform standardized tests independently, and provide a documented report. The software is in charge of conducting test scenarios (flow, temperature control, test sequences according to standards, etc.), tracking measurement results, performing calculations and editing a result report.
Operating mode
The test bench generates pressure using slave pumps and controls the controls the movement of the joysticks operating the taps, mixer taps using motorised actuators. These actuators are mounted on a C-beam which allows flexible attachment of all types of valve. When the devices to be tested are positioned on the test bench, pre-programmed test scenarios are run to measure pressures, flows, positions, torque and operating force.

OPTIONS
Linear actuator
The linear actuator can be used to operate valve controls such as the flow rate of a mechanical mixing valve, diverter controls, timed valves, etc. It features force and position measurement, and can be controlled in terms of position, speed and force.
Rotary actuator
The rotary actuator is used to operate rotary valve controls. It features torque and position measurement, and can be controlled for position, speed and torque. The output shaft is a splined hollow shaft that can accommodate a wide range of tooling. It can also be coupled to a linear actuator (to operate single-control mechanical mixing valves, for example).
Cooling by-pass
Internal tanks for temperature control by exchangers on external sources
Temperature control vessels regulate hot and cold water temperature within the bench, and are therefore independent of external power supplies. Thanks to the limited volume of the tanks, temperature setpoints can be changed in less than a minute, and high-precision temperature control is possible whatever the test conditions and bench power supply. Heating and cooling capacities are provided by external water supplies, which may be an existing plant circuit or independent hot and cold water loops.
Automatic stop
Automatic shutdown in the event of leakage or abnormal operating torque.
Tests de pression statique jusqu’à 16 bar
This system enables leak testing at high pressures, up to 16 bar, when the valve is in the closed position.

Rapid hot water temperature reduction
This system enables a sudden drop in hot water temperature to 12°C in a matter of seconds. In particular, it is used to characterize the behavior of thermostatic mixing valves in the event of a sudden change in hot water supply temperature.
Motorization of device mounting plate
Motorization of the valve mounting plate enables the valve to be positioned precisely and easily in relation to the actuator mounting beam, along 2 axes (translation and rotation). Thanks to program control, the user can memorize a particular test position associated with a particular type of valve.
Water distributor for hot and cold circuits for energy savings and closed circuit
When the water supply circuit to a bench is a closed circuit, the Splitter returns the mixed water mixed by the tap to the hot water circuit on the one hand, and the cold water circuit on the other, in proportion to temperature. Thanks to this system, the heating and cooling capacities of the hot and cold water generators can be significantly reduced.
