Release unit
PNEUMATIC EMCO WHEATON

Our pneumatic Quick Release System provides automatic disconnection of a loading arm in the event of a tanker accidentally driving away whilst simultaneously shutting off the product flow both upstream and downstream of the disconnection point.

The system is used at single loading arm stations and bottom loading stations.

The quick release unit is fitted as an integral part of the outboard end (B-dimension) of the loading arm. Both valves are clamped together by a collar assembly and the clamp is released by a pneumatic cylinder. A limit switch fitted to the double swing joint, and controlling the rotation angel, activates the cylinder.

The connecting flange sensor and a shear pin, also fitted to the double swing joint, prevent accidental release whilst maneuvering the loading arm.
