The application of carbon based thin film on gate valve seats can reduce the viscosity risk of thermal spray coating on underwater valve seats, thereby improving the functional reliability of valve seat components in deep sea and high pressure.
The advantages brought include:
Significantly reduce friction on thermal spray coating (WC Co) sliders.
Reduce friction torque in water, gas, and high temperatures.
Excellent wear resistance.
Superior sealing performance.
Long term exposure to high-pressure and high-temperature environments ensures service stability.
