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 fillmore
