Valve Leak Test System using "Differential Pressure with Water"
Water valves with diameters of 20-100mm can be leak
tested both internally and externally using the 'differential
pressure with water' technique.
The features of the machine include easily removable tools for
the variable diameters of valves and torque control for closing
the valve, and rotation control at opening and closing of the valve.
The control panel is accessible, with a keyboard for the setting
of parameters, such as programmes, times, alarm points and pressures.
The display indicates the test process, pressures and a test result
in pascals. A separate pump stand allows access for maintenance.The
measurement pneumatic equipment is contained within a separate enclosure.
There is a pressure tank and return water tank with requisite filters
and valves included, and a sugevac vaccum pump for vaccum pumping
of the valve before filling with water, which provides a high filling
rate and eliminates the fill time before pressure stabilisation.
the maximum external test pressure is 25 bar. A drip tray is placed
under the fixture to collect waste water and at the lowest point,
there is a pump for the evacuation of waste water.
Upon activation of the start button, the valve is automatically
loaded and the protective guard descends, and automatically locks.
The guard may be opened after the test pressure has been reached
to allow for visual leak location. The machine is equipped with
clear protective guards and safety switches on three sides to allow
for valve maintenance and filter exchange.
