The environmental systems suppliers generate revenues of over $100 billion per year. The systems they supply include valves valued at nearly $1 billion/yr. This is the conclusion reached by the McIlvaine Company in N028 Industrial Valves: World Market.
The largest segment of the market is for valves dealing with water and slurries. Valves used for fabric filter pulse cleaning and air monitoring valves are the exception. Some of the individual valve purchases are substantial. The knife gate and ball valves used in a large power plant flue gas desulfurization system cost over $1 million. ITT, Pentair and Crane purse this market with dedicated sales people.
