BOLTED COVER SWING CHECK VALVE
Check valves (Non Return Valve ) are used to prevent reverse flow.
The design of check valves is very simple . A hinged door is placed
inside the Swing Check Valve body . With the pressure coming
upstream the door is held open; when pressure increases on the
downstream side, it forces the door to valve close, stopping any
back flow. These valves are most often used to protect rotating
equipment such as pumps or turbines from the effects of flow
