Check Valve

Check valve is an automated fluid control device designed to prevent medium backflow. Its core function is to ensure that the fluid can only flow in one direction, thereby avoiding system damage or equipment failure caused by backflow.

Widely used in water treatment, petrochemical industry, HVAC and other fields, check valves rely on their reliable anti-backflow function to ensure the safety and stability of system operation.

Raw material key testing

Raw material testing focuses on the proportion of stainless steel content, weight, length and surface treatment.

We use chemical analysis to ensure that the composition meets the standards, weigh to confirm the weight, measure the length to ensure cutting accuracy, and evaluate the quality of surface treatment.

Accessories

SGON valves feature sealing strips made of RPTFE, offering superior high-temperature resistance, chemical corrosion resistance, and a longer service life compared to standard PTFE. Additionally, SGON uses 304 stainless steel for bolts, nuts, and gaskets, ensuring greater durability and stability than the commonly used 201 stainless steel.

Processing

SGON valves use advanced automated lathe processing technology to ensure higher precision and stability. This automated production process not only improves production efficiency, but also reduces labor costs, thereby ensuring product quality while providing more competitive prices.

Production Capacity

SGON has 80 advanced equipments, including automation equipment, CNC lathes, press testing machines and tapping machines, etc.,

with an annual output of 2 million sets, to ensure efficient production and quality product supply.
