Model SI-7

Test bench SI-7 is used for make of hydraulic and pneumatic tests of valve according to followings:

1. Maximal clamping force is 500 ton.

2. Type of valves: Gate Valve, Globe Valve, Check Valve, Butterfly Valve, Plug Valve, Ball Valve.

3. Size of valve according to maximum test pressure:

SI-7 included:
- Test bench;
- Pneumatic and hydraulic station used for creation of high pressure of water test up to 300 bar and air test up to 6 bar, and measurement of test results;
- Pump station is source of pressure which used for work of hydraulics of test bench;
- Control panel with digital monometers used for control of testing process;
- Circulation water supply system used for independent support of testing process in necessary volume of water with corrosion inhibitor;
- Electric box;
- Complete set of caps.

4. Test bench is used for following operations:
- Shell test (strength test and hardness test) with water, maximum test pressure up to 300 bar (4275 psi) ;
- Shell test (strength test and hardness test) with air, maximum test pressure up to 6 bar (85 psi);
- Seat test (leakage test) with water of seat, gland seal and gasket joint, maximum test pressure up to 300 bar (4275 psi) ;
- Seat test (leakage test) with air, maximum test pressure up to 6 bar (85 psi).

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

6. Type of valve connection: flange and welded (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 РN ;
- Seat test (leakage test) with water: pressure test = 1,1 x РN ;
- Seat test (leakage test) with air: pressure test = 6 bar (85 psi).

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

9. Kind of test bench: horizontal.

10. Type of clamp : Horizontal bilateral clamp between tables without deformation of valve body at test (We use of self-sealing caps):

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: digital monometer, visual.

12. Control panel has all necessary devices for measurement and control of testing .

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

14. Maximal distance between test tables: 1280 mm

Maximal size (diameter) of testing tables: 575 mm

Maximal weight of valve : 2740 kg

Inner distance between columns: 1640 mm

Height of valve axis from soil : 1130 mm
