Specialize in stainless steel floating balls, trunnion balls, hollow balls and hard-sealed balls. We offer straight-through, elbow, tee, V-type, W-type, hemispherical, orbit and long-handle spherical products, as well as customized non-standard balls in special shapes and materials per drawings and specifications.

Metal valve seat adopts metal hard-seal structure, manufactured by precision machining and hard alloy surfacing. It owns outstanding high temperature, high pressure and wear resistance, suitable for petroleum, chemical, power and pipeline engineering with harsh working conditions. High temperatures: above 260 ºC the use of soft seats is not recommended.Abrassive media: even small particles can damage soft seats.High Velocity in opening/closing cycles: this action can perfectly deform the soft ring and destroy the seat.

Stainless Steel Valve Stem offer a full range of austenitic (304/316), martensitic (420/440C) and precipitation-hardening (17-4PH) material solutions.Through precision cold drawing or CNC turning forming, the dimensional accuracy is controlled within ±0.01mm, and the straightness is less than 0.02mm/m. The surface can be treated with mechanical polishing, electrolytic polishing or hard chromium coating, and the Ra value can be below 0.2μm. Covering ISO 5211, DIN standard and non-standard interface, the working temperature covers -196°C to 450°C, widely used in the chemical, pharmaceutical, food and shipbuilding industries of corrosive media and sanitary conditions, taking into consideration the corrosion resistance, wear resistance and assembly interchangeability.
