EW Fuel Management supply the loading valve model 504 which is used as standard on our 3″and 4″ top loading arms for hydrocarbons. Loading Valves are available in two configurations, hold open or stay open type.
The Hold Open Valve requires the operator to manually hold the valve open through the entire filling operation, on releasing the valve lever the valve will shut off the flow.
Furthermore, the Stay Open Valve allows the operator to move the lever to the open position, the valve will remain in the open position until the operator moves the lever to the close position to stop the flow.
Model 2305 micro-switch can be mounted onto the loading valve to signal valve in the open or closed condition.
