Compatibility test

Test Background

The seals inside the valve and the valve body material need to be compatible with the coolant for a long time and need to work in coordination with the pump and sensors. Insufficient compatibility may cause corrosion, swelling, or inaccurate control.

Test Introduction

The compatibility test verifies the comprehensive matching of the valve in the liquid cooling system through the static corrosion test of the coolant and the flow linkage control test of the pump-sensor-valve.

Testing Objectives

Verify the compatibility of the valve body and sealing materials with the coolant

Evaluate the response consistency of the valve in dynamic control

Ensure there are no abnormalities when working in coordination with the pump and sensor

Verify the compatibility of communication and control protocols

FAQ
Q: How do solenoid valves and control valves cooperate in a liquid-cooling system? A: The shut-off valve is used for fault isolation, and the control valve is used for flow control. The two cooperate to achieve system redundancy and precise regulation.
