How to operate the food grade sanitary ball valve?

1. Make sure that the pipeline and food grade sanitary ball valve have been flushed before operation.

2. The operation of the food grade sanitary ball valve drives the valve stem to complete rotation according to the input signal of the actuator: when it rotates 1/4 turn (90°) in the forward direction, the valve is closed. When the reverse rotation is 1/4 turn (90°), the valve opens.

3. When the direction indicating arrow of the actuator is parallel to the pipeline, the food grade sanitary ball valve is open; when the indicating arrow is perpendicular to the pipeline, the valve is closed.



How to maintain food grade sanitary ball valve?

1. Keep the valve in the half-open position, flush and remove the dangerous substances that may exist inside and outside the food grade sanitary ball valve.

2. Close the ball valve, remove the connecting bolts and nuts on both flanges, and then completely remove the food grade sanitary ball valve from the pipeline.

3. Disassemble the drive device in order: actuator, connecting bracket, lock washer, stem nut, butterfly shrapnel, glam, wear-resistant piece, stem packing.

4. Remove the body cover connecting bolts and nuts, separate the valve cover from the valve body, and remove the valve cover gasket.

5. Make sure that the food grade sanitary ball valve is in the "off" position, which can easily take it out of the valve body, and then take out the valve seat.

6. Gently push the valve stem down from the hole in the valve body until it is completely taken out, and then take out the O-ring and the lower packing of the valve stem.




What is the solution for food grade sanitary ball valve failure?

1. Remove the protective covers on both sides of the flange, and rinse and clean with the food grade sanitary ball valve fully opened.

2. Before installation, the whole machine should be tested according to the specified signal (electricity or gas) (to prevent the vibration caused by transportation from affecting the performance), and then it can be installed online (wiring according to the wiring diagram of the electric actuator).

3. Before preparing to connect with the pipeline, flush and remove the remaining impurities in the pipeline (these substances may damage the valve seat and ball).

4. During installation, please do not use the actuator part of the valve as a lifting point to avoid damage to the food grade sanitary ball valve actuator and accessories.

5. This kind of food grade sanitary ball valve should be installed in the horizontal or vertical direction of the pipeline.

6. The pipeline near the installation point should not be drooping or bear external forces. Pipe supports or supports can be used to eliminate the deviation of the pipeline.

7. After connecting with the pipeline, please use the specified torque to cross-lock the flange to connect the food grade sanitary ball valve bolts.
