Heavy Duty Check Valves with Push-to-Connect Fittings for Drinking Water. The metal body is more durable than plastic. WebA check valve provided with a spring or counterweight begins to open when a certain static differential pressure (upstream pressure minus the downstream pressure acting on the valve) across the valve has been reached. This produces an opening force (pressure differential x cross-sectional area of valve), acting against the closing force.
