Product Introduction
Grooved resilient swing check valve is a one-way check valve.
When the medium flows forward, the valve disc opens under the action of fluid pressure.
When backward, the valve disc closes under spring elasticity and reverse fluid pressure, which cuts off the passage and prevents backflow.
