Neles globe valves are certified to SIL 3.

Válvulas segmentadas

Neles™ segment valves are economical high-performance control valves designed for liquid, gas, vapor and slurry control applications - especially those with high capacity and wide rangeability requirements. The Neles™ R-series offers light weight, low torque control valves from 1" low-capacity models up to 32".

Válvula de tanpón excéntrica

Neles™ Finetrol™ eccentric rotary plug valve is designed for liquid, gas, vapor and slurry control in general and demanding applications. Neles Finetrol is certified to SIL 3. Excellent control performance and capability to handle impure fluids makes Finetrol well suited in refining and petrochemical industry applications.

PV/PVE pinch valves

Flowrox PV, PVE and PVE/S heavy duty pinch valves are designed for shut off and control applications involving abrasive or corrosive slurries, powders or granular substances. In the open position, the valve is full bore with no flow restrictions. During closing, two pinch bars squeeze the valve sleeve shut on the center line. Bubble tight shut-off is provided even if solids have built up on the sleeve wall.

Controladores de válvula

High availability and easy interpretation are the key success factors in effective field device data analysis. Valmet valve controllers support standardized technologies and ensure the availability and usability of diagnostics information independent of your control, safety or asset management system.

Válvulas de mariposa

Neles™ butterfly valves are designed to truly optimize the efficiency of process operations by offering best-in-class valve capacity. They provide long-lasting tightness and industry-leading valve reliability, certified to SIL 3. Our product range includes both metal and soft-seated and rubber-lined butterfly valves.

Válvulas de bola

Our ball valves are designed to meet the requirements of the process industries with improved process safety and efficiency. Our proven technology in design, materials and coatings enhance process reliability in the most demanding shut-off and control applications. For control applications our ball valves provide famous Q-trim™ technology for noise attenuation and cavitation prevention. A wide range of product certifications include fugitive emission, fire-safe and SIL 3.

Actuadores neumático

Neles™ double acting and spring return quarter-turn actuators are designed for use both in modulating control and on-off service. These actuators offer an extremely long cycle life and are well suited for almost any type of rotary valve.

Your one-stop shop for control valves

What do you look for in a control valve supplier? When it comes to control valve requirements no two are ever the same. It is not just the pressure and temperature of the process or the required controllability, but also issues such as the need to prevent cavitation, to control noise, to keep within emission limits, etc. This means selecting a control valve always requires due care and attention.

Valvulas aseguran la confiabilidad de la central eléctrica de Naantali

El proceso de la planta de energía implica condiciones desafiantes y la planta debe permanecer en funcionamiento continuamente. Las válvulas de control son una parte pequeña pero importante del proceso: controlan el flujo y mantienen estable el proceso de la planta de energía, lo que ayuda a garantizar que la planta funcione de manera eficiente.

How to choose control valves?

Control valve requirements often differ depending on the process area, application and end user specifications. Process conditions and the range of parameters also vary widely, including pressure, temperature, controllability, cavitation risk, environmental impact, noise and more. Plus, priorities may differ. An end user may want to know more about a valve’s performance, controllability and total life-cycle cost, whereas an EPC contractor may be more concerned about the CAPEX-related costs and delivery times. How do you know where to start – and where to turn for help with quality information you can rely on?

Válvulas de control confiables: La base para el rendimiento del proceso y el tiempo de funcionamiento.

Al considerar el rendimiento del control en una planta de proceso moderna, es fácil confundirse con la complejidad de todo. El sistema de control suele ser la parte en la que los propietarios de plantas se concentran más. Sin embargo, no se debe olvidar que el último elemento de control, la válvula de control, establece la línea de base para un control preciso.

Determining the control valve pressure drop for control valve sizing purposes

Our guest writer Jon F. Monsen discusses the correct method for determining the control valve sizing pressure drop when the system already exists or has been designed.

Flowrox control and shut-off pinch valves succeed in ore and water treatment plants in a Spanish mine

After seven years of implementation of Flowrox™ pinch valves in a concentration plant, customer remains satisfied with the cost savings combined with reliable operation and easy valve maintenance. All 330 pinch valves were installed in an extension of their ore and water treatment plant. The project basically consisted of duplicating the size of an existing plant.

Control valves for industrial applications

General service and economical performance

Neles offers a wide range of linear and rotary valves suited to general service in a wide range of industries. Our globe valves are considered an excellent choice for general and high differential pressure applications. They are great for clean flow media and known for their ability to resist noise and cavitation. For fibrous or dirty flow media, such as those often found at pulp mills, our segment valves offer high-capacity performance, often at lower nominal valve sizes. This makes them an economical and reliable valve choice.

Bigger sizes and demanding applications

Our butterfly valves are an attractive choice when looking for an economical, lightweight control valve in larger sizes. They typically offer a high flow capacity and lower fugitive emissions. For more demanding applications, such as those found in many refineries or petrochemical plants, we recommend our eccentric rotary plug valves due to their excellent ability to handle dirty fluids with particulates.

Rough and rugged reliability

For some especially rough applications with both high-pressure and high-capacity requirements, our heavy-duty ball valves can deliver the needed performance, reliability and durability. For especially demanding applications and process conditions, Neles offers a range of solutions to avoid the negative impact of noise, flashing and cavitation.
