Test stand for hydraulic components type GT-90/EW
GT-90/EW, conforming to Machine Directive 98/37/CE, is a test stand specifically developed, for testing and easy setting of hydraulic
components; flow rate up to 35 l/min at pressure 50 bar and up to 3,5 l/min at 350 bar: it is also possible to obtain flow and pressure
diagrams, repeatibility and hysteresis data, leakages and seals tests, etc.
Following components can be tested and setted, according to specific procedures supplied with the test stand:
- pressure, flow and directional control valves, also with external pilot (up to two values of pilot pressure);
- solenoid valves and other distributor, with different supply voltages (rectifier and transformers are incorporated in the electric
installation) and for different controls (manual, mechanical, hydraulic. etc.);
- cylinders of any type.
Test stan, mobile on four wheels, includes: electric equipments, hydraulic power pack and controls, standard connecting plates for
valves, fittings and flexible hoses.

STANDARD ACCESSORIES
A complete set of accessories are supplied
with test stand to allow the proper testings
and settings for any hydraulic component,
connected to relevant actuators and to pilot
and drain ports.
• Set of intermediate fitting plates can be
mounted on top of the base-plate BA509/DR to reduce the surface from size 25
to size 16 or 10 or 06 (see fig. 4.1).
• Tooling for fast coupling of solenoid valves
type DH and DK together with modular
components (see fig. 4.2).
• Four flexible pipes (Ø9.5 -21.6mm) with
3/8” GAS thread connections (L=1,5 m);
they are equipped with 8 fittings for fast
coupling at their ends.

INSTRUCTIONS FOR USE
Testing and setting operations can be easily
performed in accordance to specific procedures, developed on this general scheme:
4.2
1) Configuration of the valve;
2) Check of flow /∆p characteristics according to the regulation diagram;
3) Pressure displaying: min/max pressure
values; adjusting sensibility;
4) Flow displaying: minimum value; adjusting sensibility;
5) Repeatibility of flow and pressure settings;
6) Check of hysteresys for pressure and
flow rate control valves;
7) Check of hydraulic leakages and seals;
8) Check of correct energizing /denergizing
of solenoid operated valves, with proper
spool switching.
