1. In a closed position, the stainless steel ball valve can be subjected to pressure from the valve stem, thereby becoming pressed against the valve seat;
When the handwheel of a stainless steel ball valve rotates counterclockwise, the direction of movement of the valve stem is reversed, and the bottom corner plane of the stainless steel flange ball valve disengages the ball from the valve seat.
3. The valve rod continues to rise and interact with the guide pin in the spiral groove of the valve rod, allowing the ball to begin to rotate without friction.
Lift the stainless steel ball valve stem to the limit position and fully open the ball valve stem.
1. When the stainless steel ball valve is fully opened, flush it clean;
2. Before installing the stainless steel ball valve, it is necessary to continuously study the system test of the complete machine according to the specified signal, and it can only be installed online after passing the test;
3. Before connecting stainless steel flange ball valves to the pipeline system, residual impurities in various pipelines must be removed;
4. During installation, the actuator of the ball valve shall not be used as a lifting point to avoid damage to the actuator and accessories;
5. Stainless steel flange ball valves shall be installed in the horizontal or vertical direction of the pipeline;
The installation point of the stainless steel ball valve near the pipeline shall not be used for low pressure or external force, but can be used to cancel the pipeline support or bracket;
