Repairs of proportional and servo valve
After designing and setting up a large number of hydraulic systems equipped with servovalves and professional valves for the demand of customers in the year, this company 1395 The repair services of this type of valves started and gradually by updating the required equipment according to the valid standards of the world (ISO4401) (ISO5598) (ISO5781) (ISO6263) (ISO626). It has provided the necessary facilities. This collection is currently equipped with 2 test stands for professional valves and servo valves, test stands for hydraulic pressure breakers, test stands for DIRECTONAL VALVE control valves, portable test boards and professional hydraulic valves and servo valves.
One of the advantages of this collection is that if there is another technical problem in the hydraulic system (other than proportional valves and servo valves), it will be easily done by the experienced engineers of this company to supply parts in the shortest possible time or to repair other equipment of your device.
How is the test and calibration done?
The servo valve test stand and the proportional valve test stand can test valves from a flow rate of 1 liter to 150 liters per minute and a maximum of 450 working pressures at different working temperatures. Also, relevant tests according to the desired valve data sheet, including leakage test leakagePressure test, flow test Flow , hysteresis test Hysteresis , vibration test, test in different temperature conditions, fatigue test Fatige and response time Response Valve opening threshold testThreshold. and symmetry or linearity test Symmetry And linearity passes to confirm its reliable and perfect performance. And after that, the valve in the hydraulic system of the press is taken and tested again according to the simulated working conditions to ensure the accuracy of its operation.
Making all kinds of professional valve boards
Repairs of servo valves and professional valves, taking into account the tolerances and the manufacturer’s standard, all parts are checked and modified. Due to the high sensitivity of the parts, all parts are washed by an ultrasonic bath machine. Among our other services, in addition Proportional valves and servo valves can be mentioned as follows:
- Construction and repair of all types of proportional valve boards (EVPD)
- Test and calibrate the settings (ADJUST) of the proportional valves according to the data sheet.
