Specialty Loading Arms

OPW – Vapor Recovery Loading Arms

This simple arm incorporates only three swivel planes of rotation and is designed for use in top loading installations where the vehicle is located at a fixed distance from the riser pipe. The two swivel planes at the inlet permit both up-and-down and side-to-side movement of the assembly, and the third swivel plane allows the drop pipe to remain vertical.

Valves can be located inboard or outboard to facilitate loading. And with a valve located outboard, dripping of viscous products after loading can be minimized. When equipped with additional swivel planes of rotation and/or drop hose, along with required outboard coupling, union or fitting, the single arm loader is adaptable to tight fill or closed loading.
