9.16 E471Loading Valve
EMCO WHEATON Loading Valves are maintenance-friendly.
The loading valve can be located on all lengths of the loading arm.
Check loading valve for leaks with each loading cycle and replace seals as
necessary. Refer to the Figure on page 16 for section views and parts list.
Instructions for Opening the Valve the First time:
1. Move the arm in the loading position. The A-length should be near or below
horizontal.
2. Open the product valve slightly to provide roughly 1/16 of the normal flow rate.
3. Once valve is free from air, open fully and allow to close. Repeat as necessary
to remove any remaining air trapped in the valve.
The valve is free of air upstream when the valve closes smoothly with a small
delay as soon as you release the lever.
Use the product valve for normal operation.
Adjustment of Closing Speed:
You can adjust the loading valve depending on the flow rate and the viscosity of
the product to close within the shortest time without a pressure line shock.
The closing time of the loading valve is set during assembly to a value which lets
about 50 to 60 L pass at a product flow of 2000 L/min until the valve is completely
closed.
To adjust the closing speed, remove pipe plug (Item #2), and using a blade
screwdriver turn the adjusting screw (Item #5). Check the closing time after each
medium turn of the adjusting screw until the desired closing-time is found.
Turn the adjusting screw clockwise to increase the closing time.
Turn the adjusting screw counter-clockwise to reduce the closing time.
