상품 특징

• Solid Brass 3/4-inch In-line Spring Check Valve 3/4-inch NPT Female Thread Unidirectional Non-return Water Backflow Prevention
• Solid Brass:The entire body of this check valve is crafted from solid brass, offering robustness and corrosion resistance for prolonged service life. The internal spring is constructed from stainless steel. No cheap, fragile aluminium or plastic materials. Working pressure: 200 PSI. Operating temperature range: -40 to +250 Fahrenheit (-40 to +121 degree centigrade).
• Heavy-Duty Thick-Wall:The premium forged brass check valve features precision-threaded ports for easy installation and connection. Large-bore connections ensure higher operational efficiency, greater flow capacity, and a compact, reliable valve body construction.
• Essential Tool:The check valve is employed in pipeline connections, primarily regulating unidirectional fluid flow within pipelines. It permits fluid movement in one direction only, preventing backflow. Mark the liquid inlet direction for convenient use and effective backflow prevention.
• Wide Application:Check valves prevent fluid backflow in fluid systems or compressed air backflow in pneumatic systems, reducing incidents and ensuring normal operation. Widely used in applications such as pump and compressor discharge cooling towers, HVAC systems, pressure pumps, sump pumps, condensate lines, and boilers to prevent backflow.
