Export Controls on Fluid Handling Equipment

Written by Eric McClafferty, Kelley Drye & Warren LLP

Pumps and Systems, August 2009

Export control agencies have continuously intensified their focus on pump, valve and other fluid handling equipment companies. In particular, there has been a great deal of enforcement emphasis on the broad, expanding export controls in the U.S. Export Administration Regulations (EAR) under Export Control Classification Number (ECCN) 2B350, which covers pumps, valves, pipes, storage tanks, heat exchangers and other equipment that can be used for chemical processing.

Late last year, construction began on an expansion project that would more than double production at the water treatment plant in the small Virginia town of Front Royal-increasing the treatment capacity from 3 million gallons of water per day to 6.5 million gallons per day. The plant had been in operation since 1960 with few modifications until the expansion plan was initiated.

When choosing a valve for an application, there is much to consider. Common concerns usually include cost, familiarity with a brand or type of valve and the method of operation. While these are certainly important factors, other considerations such as chemical resistance, abrasion, temperature and pressure relationships and future maintenance can often be overlooked.

Power Plant Emissions

Sulfur emissions are one of the most environmentally harmful air emissions from coal fired power plants. Sulfur creates an unpleasant haze in the atmosphere and causes human respiratory problems. It returns to the earth in rain, commonly known as acid rain, which destroys plants in streams and lakes. The water may look clean, but fish die from the lack of a food source.

Cavitation Prevention

Pumps & Systems, October 2008

The Telltale Signs of Cavitation

In water distribution systems where high pressure differentials and high flow rates are present, valves, piping and equipment really take a beating. When automatic control valves are exposed to such conditions, they will often exhibit vibration and excessive noise, letting the operator know that the pressure differentials and high flow rates are taking their toll. When these "symptoms" appear, they are clear indications that cavitation is occurring and will be followed by diminished performance and failure.
