Severe Service Applications
49000 Series The 49000 Series is a large capacity control valve designed with an over-sized body area to house multi-stage V-Log Energy Management trim. The 49000 series can be applied through a wide range of products from high pressure drop anti-cavitation liquid designs through low noise gas and steam applications. Available in both globe and angle style designs and incorporating the Lo-dB and V-Log trims, the 49000 series provides a flexible solution to fit high pressure drop applications in any pipe size or process fluid application.	72000 Series Dresser Masoneilan designed the 72000 Series family of energy management and low noise products for use in compressor anti-surge, gasto-flare and other venting applications where high noise attenuation and high flow capacity are required. The 72000 Series is a fabricated angle valve to offer effective solutions for customers’ specific process needs. For addressing your most severe, high expansion ratio applications, custom V-Log trim options are readily available.	77000 Series The 77000 Series multi-stage expanding area control valve is designed primarily for high-pressure compressible fluid or two-phase applications. It effectively controls erosion, vibration, and high noise conditions, making it an ideal solution for high-pressure, high temperature, flashing hydrocarbon liquid services. Typical applications for this design include a range from hot high-pressure separator control in hydroprocessing applications to gas well-head control in off-shore choke valve as well as a reliable solution for high pressure gas letdown with entrained debris.
78400/18400 Series Axial flow LincolnLog® design utilizes a tortuous path to distribute pressure drop along the axis of the plug. The axial stages throttle in unison as the plug strokes, maintaining staging ratios at all lift points. Velocity and pressure drop are controlled, thus eliminating cavitation and the resulting trim damage. This valve is highly effective in pump recirculation and highpressure liquid letdown applications.	79000 Series The 79000 Series is an angle body design developed to use the VRT® Variable Resistance Trim for high pressure liquid letdown applications. The anti-cavitation VRT trim is best used when optimally designed to match the pump flow curves, allowing steady operation as the plant is brought up to speed and the plant comes on line. The 79000 Series can be enhanced with a partial stack design to allow higher flow rates as the percent lift is increased.	84000 Series The 84000 Series SteamForm®, steam conditioning valve, is built off a flexible platform to condition steam under a full severity range of conditions. Designed to use a wide range of trim options the SteamForm operates from a range of low pressure steady state process steam applications to intermittent, rapid response turbine bypass. Built from patented technology the SteamForm valve uses precision spray nozzles and a proprietary water injection design to desuperheat and trim designs to thermally compensate for high temperature cycling for installation in the most severe steam environments.
