The double piston effect seat design in the API 6D is also called the Double-Isolation-and-Bleed Valve DIB Valve. In the closed position ball is pushed against the seat by the pressure of the fluid from upstream and hence can pressure seal the downstream of the valve. ball check valve design principles.
Ball Check Valve Design Principles, In some designs the body itself is split into two sections that bolt together. The interior surface of the main seats of ball check valves are more or less conically-tapered to guide the ball into the seat and form a positive seal when stopping reverse flow. This device requires some pressure to compress the spring and open the valve.

Ball Check Valves are simple and compact and commonly used on small water or wastewater pumps where economy is important. Fluid flowing to the right will push the ball bearing against the spring and open the valve to permit flow. A Ball Check Valve consists of a threaded or flanged body with internal features that guide a rubbercoated ball in and out of the seat as the flow goes forward and reverse.
In dynamic conditions flow The water pressure exceeds the spring tension.
Specialist in the design and manufacture of high integrity isolation valves. I used Algor to do the CFD and found it necessary to restrict the flow up to 60 GPM into the face of the ball or the flow speed and pressure at the ball face would cause the oil to burn. In a check valve whose disc travel is linear the percent of flow area will be equal to. Ball valve design in which the ball is not rigidly held on its rotational axis is free to float between the seat rings. In the closed position ball is pushed against the seat by the pressure of the fluid from upstream and hence can pressure seal the downstream of the valve. The spring tension forces the plunger into its seat keeping the check valve closed.

In some designs the body itself is split into two sections that bolt together. Like valve bodies bonnets vary in design. Although manufacturers claim their check valves are leak-free in one direction of flow and allow free flow in the reverse direction a tiny scratch wear mark or imperfection on the poppet or scat will permit some leakage. The ball valve can be closed tightly by 90 degree rotation and small rotational torque. Types of Check Valves. Check Valves And Pumps.
In static conditions no flow The check valve is normally closed. The ball is free to rotate resulting in even wear and a wiping action between the ball and seat. This ball rotates freely when fluid passes through the system which causes a wiping motion and even wear between the ball and seat. Ball Valve structure and working principles.
