    • IP / NEMA Weatherproof enclosures

      • EN60529 Standard defines IP indicator to specify the weatherproofness of a device. First digit refers to protection against solid objects: number 6 corresponds to dust tightness. Second digit refers to protection against moisture/watertightness. Electric actuators are not designed for permanent water submersion; however, temporary immersion is possible from IP67 upwards.
        - IP65: Protected against water jets
        - IP67: Protected against the effects of immersion (max. 1m deep & 30 min long)
        - IP68: Protected against submersion (time lapse & depth to be specified,
        ex: 5m/72h or 10m/96h)
      • American Standard NEMA proposes another classification for actuator weatherproof enclosure protection: NEMA 4, 6, 6P and 6X according to working environment, up to protection against submersion.
    • Protection for explosive atmosphere

      • Electric actuators working in explosive atmosphere require a specific enclosure protection submitted to dedicated certification.
      • According to market areas, there exists several types of explosion proof certifications:
        - European ATEX
        - International IECEx
        - US NEMA 7 & 9
        - Customs Union for Belarus, Kazakhstan and Russia
        - INMETRO for Brazil
        - CQST for China...

      Focus on ATEX European Directive

      The European directive 94/9/CE states the conditions to be met for equipment items used under potentially explosive atmosphere. It classifies the installation areas according to groups and categories:

      Ex de
      OR

      Equipment with electric connection in increased safety "e" (tight terminal box). The remaining parts of the electric equipment are in explosion proof "d" enclosure.

    • Nuclear site

      • Nuclear Power Plants required special design of actuators which are qualified according to RCC-E or IEEE safety standards and can be installed either inside or outside containment area.
      • The RCC-E and IEEE documents specify the rules for design, qualification and construction of electrical materials for nuclear power plants.
      • Three main levels of requirements and qualification exist depending on the type of application. Please note that these three types of application exist in all standards but may be named differently.
      • The three levels of requirements are :
        - Non safety requirements (NC) : actuators designed for operation in normal environment for 30 years (referred as "NC" type in the RCC-E standard)
        - Safety requirements outside containment (Nuc OC) : actuators designed for operation in normal environment for 30 years and during seismic accidents (referred as "K3" type in the RCC-E standard)
        - Safety requirements inside containment (Nuc IC) : actuators designed for operation during 40 years in ionizing environment and remaining operational in case of seismic accidents and LOCA, Loss of Coolant Accident (referred as "K1" type in the RCC-E standard)

    • Modulating performance criteria
    • Resolution

      • The resolution is the smallest achievable step at the output shaft of the electric actuator.
      • This is the most important performance criterion to ensure efficient modulating since it refers to the ability of the actuator to promptly operate the valve by little steps.
      • Practically, if we have a minimum output change - resolution - equals to 2%, then:
        - 2% means 2% of the total travel of the valve.
        - Therefore, a resolution of 2% allows the actuator to reach 50 steps along the total travel. Similarly a resolution of 1% would allow the actuator to reach 100 steps along the total travel.
        - For a Quarter-turn actuator: 2% of 90°= 1,8°(minimum output change would be a rotation of 1,8°)
    • Dead band

      • The dead band is the range through which an input signal may vary, upon reversal of direction, without triggering any observable change in the position of the valve
      • For example, a dead band of ±1% means that, if the actuator receives the order to move to position x, it must finally stop within an interval of
        [x-1%; x+1%]
      • Obviously, an actuator with a dead band of 1% will be more performant for modulating than an actuator with a dead band of 2%
    • Response time

      • The response time is the time needed by the actuator to reach the required position following an input signal change.
      • Usually, the electric actuator piloting a valve must reach a specific position as quick as possible to ensure an optimal control of the process. This is even more relevant when it comes to small changes of valve position. Therefore, response time is a key performance criterion.
      • In order to measure the level of performance of an actuator regarding response time, we usually compare « T63 ».
      • T63 is the lapse of time needed by the actuator to reach 63% of the output step when it receives an input signal of 2%. This a reference time measurement called time constant.
      • The response time is the addition of the dead time (time without any movement) and time constant T63.
    • Linearity

      • The linearity refers to the idea that the percentage of change in input signal must approximate the percentage of change at the output of the actuator.
      • Indeed, a valve is called linear when the flow is proportional to the opening position of the gate.
      • Most of modulating valves are linear. But depending on the type of valve, linearity may vary.
      • In case of strong non-linearity of the valve, it may cause instability of the modulating process. Therefore, the valve must be operated only through its most linear portion to ensure modulating duty.

Two steps to select the actuator in accordance with your need

STEP 1: EN15714-2 Standard defines a duty classification for an electric actuator to operate the valve. This duty classification defines basic design requirements.

Select Actuator Duty

Class A
On-Off

The actuator is required to drive the valve through its entire travel from the fully open position to the fully closed position or vice-versa.

Class B
Inching / Positioning

The actuator is required to occasionally drive the valve to any position.

Class C
Modulating

The actuator is required to frequently drive the valve to any position between fully open and fully closed.

Class D
Continuous modulating

The actuator is required to continuously drive the valve to any position between fully open and fully closed.

Process requirements

Endurance Criterion

Considering On-Off applications (Class A), process requirements imply to set ENDURANCE (lifetime of the actuator - number of cycles) as the decisive criterion.
Indeed, endurance requirements will not be the same for all market applications (for instance, due to difference of lifetime of installations).
That is the reason why, according to customers' process requirements, BERNARD CONTROLS offers:

  • Class A actuators, complying with EN15714-2 Standard,
  • Class A+ actuators with improved endurance / lifetime.

Process requirements

Endurance Criterion

Considering Inching/Positioning applications (Class B), process requirements imply to set ENDURANCE (lifetime of the actuator - number of cycles) as the decisive criterion.
Indeed, endurance requirements will not be the same for all market applications (for instance, due to difference of lifetime of installations).
That is the reason why, according to customers' process requirements, BERNARD CONTROLS offers:

  • Class B actuators, complying with EN15714-2 Standard,
  • Class B+ actuators with improved endurance / lifetime.

  • Inching / Positioning Class B

    • What is Fail Safe ?

      For all part-turn applications, spring return FQ range actuators ensure the immediate and automatic opening or closing of the valve even without any power supply, as soons as an emergency signal is activated.

      This signal can be activated following:

      • an abnormal event (fire, overflow ...)
      • an automatic control
      • an operator's action
      • or the lack of power supply

      Examples of applications: storage and distribution of gas and dangerous liquids, fire protection systems, protection of chemical facilities, air conditioning and ventilation of hazardous areas.
