Downstream processing and Chemical manufacturing is an important part of the Oil and Gas Industry which draws on equipment designed to satisfy similar API and ANSI specifications to those used in hydrocarbons production projects. Generally the size of piping, the valves and other equipment used in these processes is much smaller than that used in Oil and Gas production. The requirements for valves intended for processing oil, gas and chemicals are lower working pressures, high working temperatures, the number of crevices and “dead” spaces kept to a minimum and the valves capable of opening and closing against pressure without creating a rapid change in pressure downstream.

These Processing Applications include Urea and Ammonia Production and these tend to be viscous and non-lubricating fluids with noxious effects if released to the atmosphere. For Downstream processing and Chemicals manufacturing, Globe Valves find ready acceptance because they are capable of giving a tight shut off at high and low pressure and maintaining this with changing temperature. They can be opened and closed to give a gradual change of flow, reducing the risk of downstream pressure shock. The body and seats are designed to eliminate cavities and crevices.

BEL Valves supplies Globe Valves for corrosive and hazardous duty, such as Urea Service. The valves can be manufactured from a range of materials, such as Austenitic Stainless Steel, and Nickel Alloys, with internal components made from suitable materials. For low temperature service such as Ammonia production, the valves are made from Low Temperature Carbon Steel with 13% Chromium trim and Stellite hard facing. When the service conditions require it, the materials of the valves can be supplied to NACE Standards. The size range includes Nominal Bores from 0.5 to 24’’ in Globe Patterns and ½” to 10’’ in Angle Patterns and in Pressure Ratings ANSI 150 to 4500 and API 2,000 to 15,000psi. Design Codes include ANSI B16.34 and API 6A.
