The HTR steam trap control valve is a labyrinth-type high-differential pressure control valve. It is suitable for the main steam trap system and extraction system of thermal power plants to control high-temperature and high-pressure drop saturated water. This valve can also be applied in the petroleum and chemical industries to control high-pressure drop saturated liquids. It is one of the key control valves in thermal power plants.
The main advantages of the HTR steam trap control valve are as follows:
The fluid channel is of a labyrinth type, which continuously changes the fluid direction, controls the fluid velocity, prevents cavitation damage, and allows a pressure difference of 20MPa.
The throttling surface is separated from the sealing surface. Different throttling elements are provided according to the flow rate. The surface of the valve trim is hardened to a hardness of HRC70, ensuring tight closure and a long service life.
The valve body assembly adopts a self-sealing structure, and the greater the pressure difference, the better the sealing performance.
The valve body assembly and the actuator are connected in a floating manner, which can eliminate the jamming caused by the misalignment of the valve core and the push rod.
