The slide sleeve type of arm incorporates a slide sleeve assembly that telescopes in and out to adjust for variations in the distance from the loading rack to the hauling vehicle. It is used primarily in small bulk plants and terminals for top loading gasoline, fuel oil, or other petroleum products. This durable, dependable and cost effective loading arm is time tested as a practical method of locating the drop tube accurately and easily. The slide sleeve is a medium duty unit designed for flow rates up to 15 ft/sec (4.5 m/sec). Higher flow rates may tend to push the inner tube out beyond the loading point.

OPW Engineered Systems Loading Valves are designed to shut off the flow without causing damaging shock in the pipeline. Pipeline shock, or "hammer," causes problems with pipe joints and instruments in the line. Fast, shockless closing is assured by use of an adjustable needle valve, and a dashpot. Air cannot be trapped in the valve so the valve does not open after closure. This variable closure rate controls shock with minimum afterflow. Loading valves are available in several styles to fill almost any liquid transfer requirement where versatility and ease of operation are desired.

The 6400 series horizontal loading valve, made in cast aluminum, is "soft closing" in order to reduce line shock. The valve connections are tank-truck (TTMA) flanges. The sturdy valve has a "deadman" feature that requires the operator to hold the handle in the open position while loading. The trim inside the body is stainless steel, which means this valve can be used for a variety of chemicals and fuels. Available seals are Buna-N, Ethylene Propylene or Fluorocarbon for versatility in handling a wide range of fluids within the parameters of the body and trim limits. Available in 3" and 4" sizes.
