Performance Testing

Discover the comprehensive performance evaluations of CRDI metering valves at crdimeteringvalve.com. Our testing procedures cover various aspects, including electrical characteristics, accuracy, temperature resilience, pressure resistance, and leak prevention. Browse our catalog to find CRDI metering valves that adhere to the highest performance standards and are tailored to meet your specific requirements.

Above are the tests needed to be done after the CRDI metering valves are finished producing. However, regular checking also very important to keep the CRDI metering valves perform well.

In order to make sure the CRDI metering valves works normally, there are some parts of CRDI metering valves needed to be checked regularly and before installing to metering valve.

① Check whether there is deformation, cracking, thread damage, quenching, leakage and rust in the guide sleeve, spring, gasket and tight cap of the CRDI metering valves. The tight cap of the CRDI metering valves must be replaced after being disassembled for more than 5 times, as shown in the following.

② Replace the tight cap of the CRDI metering valves and the copper gasket of the CRDI metering valves

③ Check whether the gap between the CRDI metering valves needle and the CRDI metering valves shell is within the standard range and whether it reaches the standard for use

④All parts should be examined for wear under a microscope at least 20 times larger

⑤ CRDI metering valves tight cap deformation, cracking, thread damage, quenching, leakage, will lead to black smoke vehicle cap, fuel metering valve damage.

⑥metering valve opening pressure greater than or less than the specified range may cause metering valve damage.
⑦ Failure to replace wearing parts in time during maintenance may lead to fuel metering valve damage.

These are some precautions you need to know to maintain an CRDI metering valves. If there are more questions about CRDI metering valves and other problems, you are welcomed to contact us, crdimeteringvalve.com will do the best to help you solve your problems.
