Cemented Carbide Valve Seat:
Introduction:
The tungsten carbide valve seat is required to have distinguished corrosion & erosion resistance. The grads specially designed for valve seat meet abrasive working environment. With good balance of toughness and hardness, valve seat has long service life to reduce maintenance frequency.
