Valve Pressure Testing

Every valve undergoes rigorous pressure testing before leaving the factory, including Shell test, sealing test, and air test, to ensure zero leakage for each valve.

We maintain a large inventory of valves, including gate valves, globe valves, check valves, ball valves, and filters, made of both stainless steel and carbon steel, to meet our customers' urgent needs.

Our workers are diligently producing and processing all the valves to ensure timely delivery to each customer.

Our factory workshops are located on the 1st, 3rd, and 4th floors. The 1st floor is the production workshop, the 3rd floor is the warehouse, and the 4th floor contains both a production workshop and a paint shop.

This JIS standard flange ball valve has a DN150 diameter; its surface is smooth, free from weld spatter, porosity, and scratches, and it is ready for shipment.

150LB -30" large-diameter lug butterfly valves, all made of 316L material, use a variety of sealing structures, and have been tested in full open and full closed positions for export to the North American market.
