Bi-Directional Check Valves |
 |
|
 |
The BDC Series B-Directional Check Valve Permits a differential flow in both directions. The free flow direction permits flow in excess of 1,000 liters a minute. The controlled flow direction with a pressure differential of 5 PSIG or more has a flow less than 2.5 liter a minute. An umbrella shaped performance flow disc allows for bi-directional flow to equalize as the pressure bias across the umbrella stabilizes.
