ZMQSY/ZDLSY series pneumatic/electric Y type trap is a new-generation steam trap specially developed and designed by our company based on the hydrophobicity of thermal power plant equipment. The product is close to a straight flow design, reducing the flow resistance, the principle of secondary throttling and reducing Erosion improves life. The valve core and valve seat adopt solid carbide, closed inner leakage ≤ VI grade, valve seat compression structure, detachable middle cavity seal design, eliminate leakage, easy maintenance and other characteristics, but also in flammable, explosive occasions Use, according to the control system or adjust the instrument signal, cut off or open the valve, so as to achieve the use of controlled parameters. Therefore, it is widely used in remote control of thermal power plants and other industries.
