Tungsten carbide Seats and Valves are applied into various oil and gas filed, oilfield valves, Coal chemical industry. In the condition of long and harsh working period , tungsten carbide valve is the best choice. At the same time, tungsten carbide valve and seat has the following advantages: low noise and high wear-resistance; high hardness, high compressive strength; Good chemical stability and

1. Excellent abrasion resistance, heat resistant 2. High wear resistance 3. High fractural strength 4. HIP sintering 5.Good impact toughness, chemical stability
