Hard alloy ball valves have evolved from traditional plug valves, featuring spherical closure elements that rotate around the valve stem axis. These components enable precise control over pipeline media flow, including cutting off, distributing, and altering flow direction. Specialized designs also support fluid flow regulation.

Precision tungsten carbide valve seat pairs are extensively used in petroleum drilling, deep-sea oil drilling, and pump valve systems. These critical components ensure reliable performance in demanding oil pump applications.

Petroleum drilling environments present extreme challenges including sand-laden wells, heavy oil wells, and high-pressure anti-sand conditions. The operating medium often contains corrosive elements such as water, gas, wax, and sand. Pump valves require superior sealing capabilities, exceptional wear resistance, and excellent corrosion resistance from ball and seat components.

• High density and exceptional wear resistance
• Superior corrosion resistance for petroleum extraction and transport
• High hardness (89.5-93 HRA) and bending strength (3200-4500 MPa)
• Stable chemical properties and outstanding impact toughness
• Significantly extends tool lifespan and reduces operational costs

As a super-hard metal representative, cemented carbides provide excellent high-temperature resistance and physical stability, making them ideal for extreme environment production and processing requirements.

• Long-term high temperature tolerance up to 800°C without deformation
• Air cooling compatibility without bursting
• Precision machining with parallelism under 0.003mm

Cemented carbide molds are widely used in hardware machining due to their superior performance characteristics. These components typically provide 10 to 50 times longer service life compared to standard alloy molds.

• Stamping dies for hard alloy and stainless steel components
• Grading molds and powder pressing dies
• Wire drawing dies and extrusion dies
• Cold dies for bolts, nuts, and frame stamping

We provide non-standard customized cemented carbide die components according to specific customer drawing requirements. Our precision tolerances meet rigorous operational standards, and we can accommodate special material requirements beyond standard specifications.
