Product Advantages

Integrally forged threaded flange globe valve with minimal leakage points, suitable for harsh conditions including high temperature, high pressure, and high erosion.

1. Integral forged valve body, available in sizes DN10–DN200

2. Dual-stem design: Upper stem features threaded hardening, lower stem has smooth surface hardening

3. Thread lubrication on upper stem isolates system media

4. The linear motion of the rotary lower stem replaces helical operation, preventing damage to the seat and tip components while reducing friction between packing and the lower stem.

5. Threaded joints welded to 1.5 times pipe wall thickness, with all welds subjected to radiographic inspection

6. Valve plugs overlaid with Stellite alloy, 6# and 12# composition

7. Precision-cast 304 stainless steel handwheel
