Hard Metal Alloy Solid Cemented Tungsten Carbide Valve Seat
Tungsten carbide mechanical seals are being used increasingly on fluid pump to replace packed gland and lip seal. Pump with mechanical seal perform more efficiently and generally perform more reliably for extended periods of time.
According to the shape, those seals are also called tungsten carbide mechanical seal rings. Due to the superiorities of tungsten carbide material, Our tungsten carbide mechanical seal rings shows high hardness, and the most important is that they resist corrosion and abrasion well. therefore, tungsten carbide mechanical seal rings are having wider use than seals of other materials.
1. High strength, high wear resistance, high precision, good temperature resistance and good corrosion resistance.
2. Mainly used for the sealing of valves of oil pumps in petroleum industry`s containing wells, viscous oil wells, sea oil wells and high pressure sulfur resistant oil wells, etc.
3. Balls and seats are used with compatible cemented carbide valve seats.
4. Precision machined cemented carbide balls of other grades and specifications are also available based on customers` demands.
5. Compatible high precision valve seats can also be made.
