Our check valves are designed to prevent backflow and ensure reliable one-way flow control in pipelines. Featuring automatic operation, fast response, tight sealing, and low pressure loss, they help protect equipment widely used in water treatment, oil & gas, petrochemical, power generation, HVAC, and maintain stable system performance.
Industrial applications, our check valves are available in swing, lift, dual-plate, ball, and axial flow designs to meet different operating conditions and project requirements.
Brass valves are designed for reliable flow control, shut-off, and pipeline protection in various fluid systems. Featuring compact structure, corrosion resistance, easy installation, and stable performance, they provide durable solutions for residential, commercial, and light industrial applications.
Available in brass gate valves, ball valves, globe valves, check valves, strainers, and air release valves, with different connection and sealing options. Suitable for water, air, gas, and other compatible media, they are widely used in plumbing, HVAC, irrigation, water supply, compressed air, and building service systems.
Hydraulic control valves are designed for automatic flow regulation, pressure control, and pipeline protection in water systems. Featuring self-operated hydraulic control, stable performance, accurate adjustment, and reliable sealing, they help maintain safe and efficient system operation without external power.
Available in pressure reducing valves, pressure relief valves, float control valves, pump control valves, flow control valves, and solenoid control valves. Suitable for water, clean water, wastewater, and other compatible liquid media, they are widely used in municipal water supply, building water systems, irrigation, fire protection, water treatment, and industrial water networks.
Pipe fittings, couplings and flanges are essential components for creating safe, continuous and serviceable pipeline systems. They provide reliable solutions for connecting pipe sections, accommodating outside-diameter differences, transitioning between plain-ended pipes and flanged equipment, and simplifying pipeline installation, extension, maintenance and repair. Flexible sealing structures can also help accommodate limited pipe misalignment and movement under suitable installation conditions.
Available in various connection designs and material configurations, the series can support connections involving ductile iron, grey iron, steel, PVC-U, PVC-O, PE and other compatible pipes. With options for mechanical joints, flexible couplings and flanged connections, these products are widely used in municipal water networks, water treatment plants, pump stations, irrigation, fire-water systems, building services and industrial utility pipelines.
Product selection should be based on the pipe material, actual outside diameter, pressure rating, flange standard, medium, operating temperature, installation environment and axial restraint requirements. Special sizes, materials, coatings, flange drilling and connection configurations can be discussed with the factory.
