Plastic Swing type-check valve

Plastic Swing type-check valve

Swing check valves feature a robust and simple design, allowing smooth flow with very low pressure drop. They respond automatically to flow changes, provide reliable backflow protection, and are easy to maintain, making them suitable for a wide range of industrial piping systems.

 Main Structural Features

• Hinged Disc–Automatically opens and closes, response time <0.5 s.
• Full-Bore Design–Low pressure loss, 30–50% less than lift check valves.
• Simple Structure–Few moving parts, 1M+ cycles service life.
• Wide Range–Sizes DN15–DN300, pressure up to PN25.

Industrial Applications

• Water Supply Systems–Prevent backflow in pipelines and pumping stations.
• Wastewater Treatment–Suitable for large flow and low-pressure-loss conditions.
• Industrial Process Lines–Used in chemical and energy industries for flow protection.
• Pump Discharge Lines–Protect pumps from reverse flow and water hammer.

 FAQ for Plastic Swing type-check valve:

Q: What media are plastic swing check valves suitable for?
A: They are ideal for corrosive fluids such as acids, alkalis, and wastewater, with chemical resistance across a pH range of 0–14.

Q: What temperature range can plastic swing check valves operate in?
A: Depending on the material (PP, PVDF, or PVC), they can operate from –10°C up to 120°C.
