• Made from durable ABS plastic,High quality Nitril-Bruna N seal,Universal design works with multiple applications
• Check valve is used in fluid system to prevent reverse flow fluid, or used in pneumatic system to prevent reverse flow of compressed air
• This check valve keeps the water from flowing back to the pump and prevents the pump from rapid cycling, extending the life of the pump
• These check valves are applicable for fluid systems to stop countercurrent liquids, or for pneumatic systems to prevent reverse flow of compressed air.
• Note: when installing the check valve, pay special attention to the flow direction of the medium; The normal flow direction of the medium should be consistent with the arrow direction indicated on the valve body, otherwise the normal flow of the medium will be cut off
