Severe service control valves

The Masoneilan 49000 Series V-LOG high pressure drop valve is designed with an expanded body gallery to facilitate gas expansion and offers up to 36 stages of pressure reduction through a trim configuration. This valve provides optimized solutions for severe service applications characterized by high-pressure drops, which may lead to damaging noise or cavitating fluid conditions. Constructed around the Masoneilan V-LOG Energy Management Trim, the 49000 Series is adept at managing a diverse array of liquid and gas services across various process industries.

The Masoneilan 71000 Series single-ported, heavy top-guided control valves are engineered with inherent versatility, making them ideal for a diverse range of heavy-duty process applications, including crude oil refining and gasification units. This valve offer:

• Streamlined Angle Body Design
• Heavy Guided, Hardened Plug Design
• Corrosion-Resistant Materials
• Low Emission Certification
• Tight Shutoff

The Masoneilan 72000 Series represents a specially designed angle valve that ensures precise capacity management while effectively minimizing noise and outlet velocities. This is achieved through the use of single or multiple cages, making it suitable for high-capacity and high-pressure gas letdown applications.

The adaptable nature of the fabricated valve body allows for tailored engineering solutions, accommodating significant variations between inlet and outlet sizes to facilitate downstream gas expansion and noise reduction. The Masoneilan Lo-dB low noise trim and V-LOG Energy Management Trim are specifically designed to manage noise and vibration in applications with severe high expansion ratios.

The Masoneilan 74000 Series valve, at its base level, is distinguished by a single-stage trim housed within an angle-style valve body, featuring straightforward flow geometry for both the valve body and trim. This uncomplicated flow path has demonstrated effectiveness in specific heavy oil applications, where high-velocity erosive jets tend to damage more intricate valve trims. The product has achieved notable success in challenging refining environments, particularly where the presence of entrained solids poses significant issues, and where other conventional severe service trims have experienced catastrophic failures.

The 74000 has garnered widespread industry recognition for its reliability in the most demanding conditions and is often specifically recommended by seasoned users. In a market seeking differentiated products, the 74000 is recognized for its unique design and exceptional performance.

The Masoneilan 77000 Series multi-stage expanding area control valve is specifically engineered for applications involving high-pressure compressible fluids or two-phase mixtures. It proficiently manages issues related to erosion, vibration, and elevated noise levels, rendering it an optimal choice for services involving high pressure, high temperature, and flashing hydrocarbon liquids.

Common applications for this design encompass a variety of functions, including control of Hot High Pressure Separators in hydroprocessing operations, gas wellhead regulation in offshore choke valves, and a dependable solution for high-pressure gas letdown that may contain entrained debris.

The Masoneilan 78400 / 18400 Series LincolnLog design employs a convoluted pathway to evenly distribute pressure loss along the axis of the plug. The axial stages operate in concert as the plug moves, ensuring that staging ratios remain consistent at all lift positions. Both velocity and pressure drop are regulated, thereby preventing cavitation and subsequent trim damage.

This valve proves to be exceptionally efficient in applications involving pump recirculation and high-pressure liquid letdown, particularly in Hydrotreater processes.

The Masoneilan 84000 Series range of steam conditioning valves presents an extensive array of features, such as low noise trim and a patented water injection system, designed for applications necessitating both pressure and temperature reduction within a cohesive framework. The SteamForm™ product line integrates over 125 years of expertise in pressure control with cutting-edge desuperheating technology, delivering a highly efficient solution for steam conditioning. The 84000 Series SteamForm™ Steam Conditioning Valve offers several advantages, including an Axial Flow LincolnLog design that employs a convoluted pathway to evenly distribute pressure drop along the plug’s axis. This design effectively manages velocity and pressure drop, thereby preventing cavitation and subsequent trim damage.

The Masoneilan 75000 Series represents an advanced solution for tank level control, specifically engineered to withstand erosive conditions and resist flashing. It is particularly suited for level control tasks involving corrosive or viscous fluids commonly found in the Purified Terephthalic Acid (PTA) chemical sector. This series features a fully ported body with a sweep angle design and a contoured gallery, which effectively minimizes pressure losses and reduces the risk of erosion caused by particle impact within the flow path.

The series is available in various configurations, including 90°, 120°, and 135° sweep angles, facilitating convenient piping connections in confined tank-mounted environments.
