Plunger valves are precision flow control devices characterized by a cylindrical plunger with a through hole, designed to regulate or isolate fluid flow in industrial pipelines. They operate by rotating the plunger to align or misalign its hole with the valve body’s flow path, ensuring tight shut-off and precise control. Composed of valve body, plunger, stem and sealing rings, they are widely used in scenarios requiring high sealing performance.
Robust structure with a smooth cylindrical plunger and high-quality sealing rings (PTFE, rubber), ensuring excellent leak-proof performance. The valve body is made of corrosion-resistant materials (stainless steel, brass, carbon steel), adapting to high-pressure, high-temperature and corrosive fluid environments. Simple construction allows easy disassembly and maintenance.
Superior sealing performance, capable of tight shut-off even for high-pressure fluids. Precise flow regulation with 90-degree rotation of the plunger, ensuring stable and reliable operation. Low friction between the plunger and sealing rings, extending service life and reducing operational torque.
Equipped with threaded connections, suitable for small-diameter pipelines and low-to-medium pressure systems. Ideal for HVAC, residential water supply and laboratory equipment due to easy installation and compact size.
Flanged connection design, suitable for large-diameter, high-pressure industrial pipelines. Widely used in petrochemical, chemical processing and power generation industries for heavy-duty flow control.
Widely applied in petrochemical, chemical processing, power generation, water treatment, HVAC and marine industries. Suitable for controlling fluids such as water, oil, gas, chemical reagents and other corrosive or non-corrosive media, especially in scenarios requiring high sealing and precision control.
