Test bench for Hydraulic and Pneumatic tests of safety (relief) valves DN 3/5"-12" (15-300 mm), maximal hydraulic and pneumatic test pressure up to 250 bars (3563 psi), and for adjustment of safety (relief) valves (model SI-15)

Model SI-15

Test bench SI-15 is used for make of hydraulic and pneumatic tests of valve according to followings:

1. Maximal clamping force is 21,5 ton.

2. Type of valves: Safety (Relief, Pilot) Valve.

3. Size of valve according to maximum test pressure:

4. Test bench is used for following operations:
- Leakage test of connection body with seat (water and air);
- Leakage test of gate of safety valve (water and air);
- Functional test (adjustment of safety valves ) ;
- Body test (strength test and hardness test) with water.

5. Test bench makes testing of valve according to standards: API 527API 598, DIN EN 12266, ISO 5208, ASTM E 1003.

6. Type of valve connection: flange and threaded (Please specify type of connection valves according to each DN valve).

7. Size of test pressure:
- Body test (strength test and hardness test) with water: pressure test = 1,5 up to 2 x �N ;
- Seat test (leakage test): pressure test = no more operating pressure of valve ;
- Functional test (adjustment of safety valves ): pressure test = operating pressure of valve .

8. Control of testing:
- At test with water - on manometer of pump station, on falling drops in dropper on pump station and visual;
- At test with air - on manometer of pump station, on device of indicator for measurement of leakages on pump station and visual.

9. Kind of test bench: vertical.

10. Type of clamp : Unilateral clamp of the valve:

11. Process of testing:
- Loading/unloading of valve on test bench: manual OR your crane
- Clamp of valve: automatic
- Feeding a test pressure: automatic
- Monitoring and measurement of test results: manometer, visual.

12. Control panel has all necessary devices for measurement and control of testing (Please be informed that control panel is included in test bench).

Source of pressure (pump station) is included in test bench. Pump station used for creation of water and air pressure, for filling water of valves, for stepless control of outlet pressure, for automatic support of outlet pressure. Name of model is PGS.

Source of pressure (compressor unit) is included in test bench. Compressor unit used for creation of air pressure, for filling air of valves, and for compression of air. Compressor unit including tanks (storage system). Name of model is UK.

13. All metal details contacting with water are protected from corrosion.

14. Maximal size of test tables: 480 mm
Maximal height of clamping claws : 60 mm
Maximal weight of valve: 650 kg

15. Test medium:
- Water (Demands for water: in 100 cubic centimeters of water should contain no more than 400 particle a size from 50 up to 100 microns)
- Air from factory pneumatic mains (Demands for air: a size of a hard particle no more than 40 microns).

16. Ambient temperature: +1 up to +40 � �.

17. Overall dimensions
•  Test bench without control panel 1025 � 808 � 960 mm
•  Control panel 706�582�1315 mm

18. Weight
•  Test bench without control panel 600 kg
•  Control panel 115 kg
•  Set of interchangeable parts 190 kg

19. You must need for test bench of following:
- Inlet compressed air with pressure 4 up to 6 bar (57 up to 85 psi);
- Inlet water with pressure 1,5 bar (21-42 psi);
- We would like to recommend for you to have of Circulation water supply system volume 1000 liters, 1500 liters, and 5000 liters.
- Electric power supply 380V 50 Hz for compressor unit.
