Valve Testing and Repair Calibration Services
This valve test benchis used for make of hydraulic and pneumatic tests of swing check valves,according to the following: 1. Maximal clamping force : Depends on the valve max. pressure 2.Type of valves: Swing check valve, gate valve,globe valve, plug valve,ball valve,control valve 3.Size of valve : DN15-DN1200 ( Can be customized as per clients's tested valves) 4.Test bench is used for following operations:- Shell test (strength test and hardness test) with water, maximum test pressure up to 700 bar (9975 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 700 bar (9975 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 etc.6. Type of valve connection: flange (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 times of body pressure - Seat test (leakage test) with water: pressure test = 1,1 times of body pressure- Seat test (leakage test) with air: pressure test = 6 bar (85 psi). 8. Kind of test bench: horizontal.9. Type of clamp : : Horizontal bilateral clamp between tables with deformation of valve body at test: 10. 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: monometer and visual.Please contact us for more information.
