Las válvulas de bola, válvulas de mariposa, válvulas de diafragma y válvulas de compuerta a menudo son automatizadas con actuadores eléctricos o neumáticos. Esto permite la operación remota por una variedad de razones: ahorros en mano de obra, seguridad de la planta, garantía de la calidad del producto y secuenciación automática, por nombrar algunas pocas. La elección del tipo de actuador depende de muchos factores, que incluyen disponibilidad de suministro de aire, requisitos de ciclado, condiciones del entorno, compatibilidad con el tipo de operación de control y costo. Los posicionadores pueden montarse en estas válvulas si se requiere control de flujo.

Characteristics:

Quarter turn valve with hyperbolic flow characteristic, low pressure drops and reliable sealing. Poor flow control, typically used in on/off applications with very little to no suspended solids. Multiport valves used for diverting, splitting lines and mixing.

Operation:

Electrical actuation (all sizes) or Pneumatic actuation (all sizes)

Characteristics:

Quarter turn valve with equal percentage type flow characteristic. Moderate flow control, can be used for both on/off and modulating service. Good tolerance to suspended solids but not recommended for use with slurries or debris.

Operation:

Electrical actuation (1 1/2" – 24") or  Pneumatic actuation (1 1/2" – 24")

Characteristics:

Multi turn valve with linear type flow characteristic. Good flow control, can be used for both on/off and modulating service. High tolerance to suspended solids, excellent for slurry service and high resistance to clogging due to debris. Bonnet can be removed for cleaning out valve.

Operation:

Electrical actuation (1/2" – 4") or Pneumatic actuation (1/2" – 10")

Characteristics:

Chemical Processing, Water & Wastewater, Landfills, Irrigation, Food Processing, Mining

Operation:

Electric 1-1/2" – 3"

Characteristics:

Chemical Processing, Water & Wastewater, Landfills, Irrigation, Food Processing, Mining

Operation:

Electric 1-1/2" – 3"
