All standard qualification testing required:

Insulation resitsance:
Tested by DC500V megohmmete for 1 min, the insulation resistance should e100M
Watertight performance
Hydrostatic pressure up to 0.5bar, leakage ratio<0.1mL/min

Hydrostatic pressure 0.5~9.5bar, leakage ratio 0mL/min
Hydraulic pressure withstand
Withstand hydrostatic pressure of 12bar for 5min, no unbroken, deformation or outside leakage
Reliability
While valve is in CLOSED position, submit to 0.1~0.1bar, on and off for 10s respectively, lasting 1h, the check valve should be unblocked.
Flow characteristics
Pressure 0.2bar Flux e0.4L/min; Pressure 1bar Flux>8L/min;

Pressure 3bar Flux >25L/min; Pressure 8bar Flux >40L/min
Across layers insulation
Withstand high voltage pulse for 2s, no damage should occour.
Continuously energized
a. Energize (CLOSED position) for 12hrs, but valve not connected to water, the valve should have no deformation, and the coil should not be burned;
b. Energize (CLOSED position) for 5 days (120hrs), valve connected to water at 60 C, the valve should have no deformation, the coil should not be burned, no leaking and normal operation afterwards.
Withstand high voltage
High-voltagepower between electric conduction and external electrified metal
Withstand AC1500V,s50Hz for 1min, no flashover or breakdown;
Withstand1800V,50Hz for 1s, no flashover or breakdown.
