It's time for you to learn more about the technical information, applications, and advantages of yet another valve in the Masoneilan portfolio.
In the universe of control globe valves, it is impossible not to mention the importance and presence of the Masoneilan 21000 as one of the references in the field.
The Masoneilan 21000 is a valve that combines the practicality of design, configurations for application in various processes, global manufacturing, and high efficiency. This makes it one of the key items in the Baker Hughes Masoneilan product line.
In this article, we will showcase the characteristics and benefits that have made it employed in the majority of industries.
Getting to Know the Masoneilan 21000 Valve
The Masoneilan 21000 is a linear, unbalanced valve used in various industries and processes. It is manufactured in standard carbon steel and stainless steel configurations, as well as in special materials such as duplex, super duplex, chrome-moly, among others.
This model is part of a set of valves with recognized quality worldwide, with a long and consistent installed base.
The Masoneilan 21000 has a wide operating temperature range, with special bonnet configurations for cryogenic services (with temperatures around -196 ºC) and for high-temperature operations (close to 427 ºC).
Its size range varies from ¾ inches to 8 inches, pressure classes from 150 to 2500, with flanged, threaded, or welded connections.
It can be of the diaphragm type, recommended for simpler operations, or of the piston type for high-pressure tasks.
Among its manufacturing features, two points deserve attention: the types of trim and bonnet, let's take a look.
Masoneilan 21000: Types of Trim
If you are new to the world of valves and not yet familiar with some terms, we'll explain: trim is the assembly that includes the stem, plug, cage, and valve seat.
In the case of the Masoneilan 21000 valve, in addition to variations in CV and types of opening, there are different special internals designs, such as:
- Trim Lo-dB and Anti-cavitation: It has a special plug to reduce excessive noise caused by gas velocity or to treat sigma conditions in liquid fluids. Cavitation is the phenomenon of vaporization of a liquid due to the reduction of pressure during its movement, damaging the metal surface of the internals. The trims come in configurations with 1 or 2 stages.
- Trim Close Clearance: Available for valves with diameters up to 1", intended for microflow control with CVs ranging from 0.1 to 1.
- Coatings/Sealing Classes: The trim of the Masoneilan 21000 valve is available in various material configurations, hardenings with coatings, and soft materials for Class VI sealing.
Masoneilan 21000: Types of Bonnet
For work with critical temperatures and fugitive emission control, the Masoneilan 21000 offers special bonnets that allow compliance with this type of process.
- Extended Bonnet EB: For work with critical temperatures, it allows admitting temperatures up to 427°C with PTFE gaskets.
- Extended Bonnet for Cryogenic Work: For control at low temperatures, it allows working with temperatures down to -196°C with TFE V-ring gaskets.
- Extended Bonnet with BS bellows: For stem emission control, it is available in standard material stainless steel 316 or Hasteloy, Monel, and Inconel.
- LE-Packing – Pure Air Compliance: The optional low-emission LE™ PACKING gasket system helps reduce atmospheric emissions from the stem sealing area. This unique feature helps promote compliance with environmental safety and emission control requirements. No bonnet extension is required for stem inclusion.
