API Coupler For Filling & Unloading

Series 513 Snap-On API Coupler

The Excel Loading series 513 semi-automatic coupler is used in the petrochemical industry when a dry coupling is required. It is mainly used to connect a bottom loading arm or a hose to a tanker equipped with a bottom loading adapter manufactured according to API RP 1004 standard regulations. The Excel Loading 513 coupler allows the final connection of the loading operation to be leak free and totally safe conditions for operators.

How API Couplers Works

Pressing the coupler to the adapter, the 5 locking lugs of the coupler automatically hook to the adaptor and the outer ring moves front-ward fixing its position. The operator has to turn the lever counter clockwise to start the delivery.

There is double security:

  1. The flow can be started only when the coupler is hooked
  2. It’s not possible to disconnect the coupler when the lever is in the open position.

To terminate the delivery, rotate the lever clockwise and to disconnect the coupler by pulling the
release handle.
