As we know, tungsten carbide throttle valve is a necessary part of the natural gas extraction industry. They are often subjected to high pressure gas erosion and corrosion, therefore, strong corrosion and oxidation resistance is very important for carbide throttle valves.

Cemented carbide throttle valve has high hardness, strong wear resistance, and strong corrosion resistance and other excellent properties of cemented carbide, which can correspondingly reduce the impact of vapor corrosion and extend the service life.

Cemented carbide throttle valve is often used with dosing pump, relief valve and actuator to form a throttling speed control circuit. If the load of the actuating element is unchanged, the pressure difference between the front and rear of the throttle valve is certain, and the flow rate through the throttle valve can be adjusted by changing the opening area of the throttle valve, so as to adjust the movement speed of the actuating element. In addition, in the hydraulic system, tungsten carbide throttle valve can also play the role of load resistance and pressure buffer, etc.
