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.
