The HH49X Type Micro-Resistant Slow Closing Check Valve is installed in pipelines or at pump discharge outlets to prevent water hammer caused by pressure differential when the pump shuts down, thereby protecting the pump from reverse rotation.

This valve features a novel structure, compact size, lightweight design, low fluid resistance, reliable sealing, smooth operation, long service life, and excellent energy-saving performance. It is suitable for use in water supply and drainage, fire protection, HVAC, and other systems to prevent damage to pumps and pipelines caused by water hammer resulting from reverse flow. Additionally, it provides a silencing effect.
