Quality Control

Our production flows with whole-process quality control:

1、 Strict raw material control:

Well protection of valve stem in case of scratch, solid replaceable seats, separated stock of valve accessories.

2、We have all kinds of mechanical test.

a、Charpy Impact Test of ZJCLV Valves:

b、Tensile strength:

c、Hardness Tester of ZJCLV Valves:

d、Spectrometer test of chemical composition:

3、 we have all kinds of NDT tests as bellow:

MT- Maginetic Test of ZJCLV Valves

PT – Penetrant Test (DPI,LPI,FDPI,PT) of ZJCLV Valves

RT-Radiographic test if needed by customers especially used for high pressure and high temperature valves:

UT Ultrasonic Technique of ZJCLV Valves which is usually used for for forged steel valves

4 、Dimension tests by time to time to control the valve quality:

a、Angle Tester especially for  CLV Valves with BW ends:

b、Dimension inspection of FTF, flange thickness B, flange holes, distance of sealing, valve ID of every batch of ZJCLV valve productions.

c、Thread inspection of the stems to promise the quality

5 、Pressure Test Machines for every piece of ZJCLV Valves

6 、Color Paint Inspection of ZJCLV Valves

7 、We also alwasy do Fire Test of ZJCLV soft ball valves as we have fireproof design in our ball valves:

8 、ZJCLV Valves can also pass Cryogenic Testing to -191 centi-degree as precise design.
