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.
Specification
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.
