Mod.Protector

The CSA Non-slam check valve protector are designed specifically to ensure a drop tight back prevention mitigating surge events . As their name implies, these valves close without slamming, meaning no excess pressure spikes are created.

The obturator of CSA a non-slam check valve protector has an internal spring opposing the opening fluid flow pressure. When the flow of a media is strong enough, the spring compresses and the valve opens; the disc is smoothly pushed back toward the seating surface in the valve by the spring as the flow decreases and stops, but before flow direction reverses thus avoiding water hammer. The needle shaped body ensures the maximum resistance to cavitation, noise and reduced headloss.
