Quality Control - SGON Valve

We improve efficiency through automated production lines to ensure high quality of valves. The accessories we use, such as sealing strips and stainless steel bolts, nuts, gaskets, etc. are better than most of our peers. In terms of processing accuracy, we use advanced equipment to achieve close cooperation.

The perfect production process covers every link from raw material procurement to finished product inspection to ensure that each product meets high standards. At the same time, we conduct multiple tests on raw materials and accessories to ensure product quality.

Procurement of raw materials

Incoming material inspection

Processing and manufacturing

Sembly and debugging

Quality inspection

Cleaning and packaging

Detection

We strictly implement the testing process. Raw materials are strictly tested to ensure performance; accessories are precision-checked to ensure the accuracy of parts; the surface treatment of the valve body blank is also strictly checked to ensure smoothness and corrosion resistance.

Raw material testing

Raw material testing focuses on the proportion of 304 and 316 stainless steel content, weighing to confirm weight, measuring length to ensure cutting accuracy, and evaluating surface treatment quality.

Accessory inspection

Accessory inspection includes precision sampling, including the consistency of the ball and valve body materials, the fit between the valve stem and the ball, the accuracy of the threads and nuts, etc., and also checks the accuracy of the gaskets.

Valve body blank surface treatment

Each valve body blank is carefully inspected after processing to deal with details such as sand holes and bumps to ensure a smooth and defect-free surface.

Accessories used by SGON

We offer high-performance sealing strips made from RPTFE, which outperforms standard PTFE used by many competitors. Our stainless steel accessories, including bolts, nuts, and gaskets, are made from 304 stainless steel, providing greater corrosion resistance and strength than the 201 commonly used in the market, ensuring reliability and durability in various environments.

Assembly

Our assembly process is rigorously controlled with a sampling inspection mechanism in place. The assembly manager, production management, and inspection team collaborate to ensure quality at every stage. Our experienced assembly staff undergo systematic training to ensure efficient and accurate operations. These measures demonstrate our commitment to providing reliable products and high-quality services.

Testing

Each SGON product undergoes rigorous component inspection and pressure testing, using advanced pressure testing machines to ensure safety and reliability. We provide customized testing solutions based on customer needs to ensure that products always meet high standards.

Pressure test

Each product is strictly pressure tested by a pressure test machine to ensure the sealing and pressure resistance in actual use.

Accessory test

Mainly for the temperature and pressure resistance of the sealing valve seat, materials can be flexibly selected according to customer needs, such as PTFE, RPTFE, PCTFE, PPL, PEEK, EPDM, etc.
