HC41X-10/16/25Q installed on the outlet pipeline of water pumps. It prevents damage caused by high-
pressure water flow impacting the pump in the event of pump shutdown. Its features are as follows:
Smooth Liquid Flow: The valve allows smooth liquid passage with minimal local head loss.
Guided Closure: Equipped with a guiding mechanism, the valve closes flexibly and provides linear sealing,
resulting in effective check function and noise reduction during closure.
Compact and Lightweight: The valve is compact in size and lightweight, facilitating easy installation and
maintenance.
