Test Performance Requirements

The equipment is used for the following performance requirements:

Body Strength Test

This is a pressure test for the tightness and pressure resistance of the complete valve shell formed by the valve body and valve cover. It is a hydraulic test. Within the specified time, no visible deformation and no leakage are considered qualified.

• When working pressure is less than 0.25 MPa, test pressure = maximum working pressure + 0.1 MPa
• When working pressure is greater than or equal to 0.25 MPa, test pressure = maximum working pressure × 1.5

Air Tightness Test

Includes low-pressure test (0.1 MPa) and high-pressure test (maximum working pressure). It is a pneumatic test using air, and no visible leakage within the specified time is considered qualified.

Shut-Off Time Test

When the internal pressure of the test piece reaches the maximum working pressure, the workpiece is manually closed. The time required for complete closure is checked by the flowmeter, displacement sensor, and manual timing.

• Below DN50: < 5 s
• DN65 and above: < 10 s

Excess Flow Performance Test

This test checks whether the valve can automatically close when the outlet medium flow reaches the rated flow. It is a hydraulic test, and the allowable deviation of the maximum flow at the moment of self-closing is rated flow ±10%. For some DN80 imported or imitation imported configurations, this function may be absent.
