Leader in mass flow meter and controller technology

Wenzhou Zhenhong Valve Ball Co., Ltd. was established in 2000. We are a manufacturer dedicated to the development of high-precision, high-tech, and multi-performance balls. Focusing on valve ball manufacturing over 20 years' experience, with 3 fully automatic forging plants and 2 fully CNC manufacturing plants, covering an area of ​​40,000 square meters and 300+ employees, daily production capacity is more than 60000 pcs and a turnover of over 25 million US dollars in 2021. With strong production innovation capabilities and years of production management experience, our factory introduced Western Siemens CNC equipment-spherical grinders, machining centers, and spherical roundness measuring instruments, we won domestic and abroad market customers' recognition and praise.

Forging

The forging process is mainly used to produce 1/4" to 48" (DN5~1200), 150LB to 2500LB (PN10~420) solid ball billets, and also used to manufacture large-size (above 24") balls, with an annual production capacity of 200​ ​00 tons, starting from raw materials, we can control quality, production capacity, delivery time and cost in one stop, making us unparalleled in the valve ball industry.

Quality Control Work Parts

Raw Material Inspection: including the PMI, mechanical properties, dimensions, wall thickness of solid and hollow ball blanks, it`s performed against per heat no. or batch.

Machining Inspection

Mainly including the visual and dimensional check, performed by 100%, besides, we have QC personals in spot for continuous random check, to make sure each dimension comply with drawing requirements

Final Inspection

Once the valve-balls are cleaned and ready for packing, our inspector will do random inspection carefully, not only the dimension, also including the roundness, roughness, concentricity, symmetry, parallelism, perpendicularity, etc. make sure each ball is qualified before deliver to our customers'hands.
