Who is Bernard Controls and what does it make?

Bernard Controls is a French group specialised in electric actuators for valves, with roots in an electric motor workshop opened north of Paris. It later moved on to actuators, and the company introduced the compact electric quarter-turn actuator, intended for the butterfly valve. Today the group has subsidiaries on several continents and a strong presence in nuclear energy, oil and gas, power and water.

The programme has several ranges. The AQ, AQL and AQXL quarter-turn actuators cover the basic functions for valves or dampers in moderate conditions; the AQL ranges from 15 to 70 Nm in three models, with IP68 and operation on alternating or direct current. The SQ, ST and STX ranges are weatherproof, with heavy mechanical construction and a handwheel with a differential system without a declutch lever. The nuclear-qualified versions (Nuc IC for inside the containment, Nuc OC for outside) comply with RCC-E and IEEE standards. For controls, the company offers INTELLI+, fieldbus solutions and SIL design. Its own technologies include travel limiting systems, torque limiters, manual emergency operation, absolute sensors and ESD functions. The ranges are chosen according to the duty class.

For Romania, this type of actuator appears in power plants, water stations and the oil and gas industry, as a spare part on imported valves or as a project choice. For a quotation, the range, torque, voltage, duty class and environmental protection matter.

What do we supply from the Bernard Controls range?

Product	Description
AQ, AQL and AQXL ranges	Electric quarter-turn actuators for the functions needed to operate a valve or damper in moderate conditions. The AQL covers torques from 15 to 70 Nm, with IP68 protection, C4 and operating temperatures from −20 to +60 °C.
SQ, SQX, ST and STX ranges	Weatherproof actuators for energy, water and industry. They have heavy mechanical construction, operating temperature from −20 to +70 °C, optionally −40 °C, and versions with integral control or explosion-proof (SQX, STX).
Nuclear-qualified actuators	Multi-turn actuators for inside the containment (Nuc IC), designed to operate for 40 years in an ionising environment and in the event of an earthquake or a loss-of-coolant accident, plus quarter-turn and multi-turn actuators for outside (Nuc OC).
Controls and communication	INTELLI+ and LOGIC controls, absolute sensors, ESD functions, open fieldbus systems and SIL design. They complete the actuators with monitoring and integration into the automation systems of the power plant or the refinery. They are chosen according to the safety level required.

How do we supply Bernard Controls in Romania?

We can quote Bernard Controls actuators based on the range and the nameplate of the existing unit. They are brought in to order, through EU supply channels or by import, usually 1–4 weeks, and nuclear-qualified versions or those with a special configuration have a lead time which, depending on the brand and the specifications, may be longer. For the request, send the range (AQ, SQ, ST, STX), the rated torque, the voltage and frequency, the duty class, the degree of protection, the control type and the mounting flange. The lead time is confirmed in the quotation.

Nuclear qualifications and new seismic certificates are issued by the manufacturer and by accredited laboratories for each project separately.

Frequently asked questions about Bernard Controls

What does Bernard Controls produce?

Bernard Controls produces electric quarter-turn and multi-turn actuators for valves and dampers, in the AQ, SQ, ST and STX ranges, plus nuclear-qualified actuators, INTELLI+ controls and fieldbus communication solutions. The main markets are nuclear, oil and gas, power and water.

How do I choose between the AQL and SQ ranges?

The AQL is for low torques, from 15 to 70 Nm, in moderate conditions, while the SQ is for higher torques and harsher conditions, with reinforced mechanical construction. The valve torque, the duty class, the working environment and the temperature range help us.

How long does it take to bring a Bernard actuator to Romania?

It is brought in to order, through EU supply channels or by import, usually 1–4 weeks. Explosion-proof versions or those with integral control may take longer. Small parts can be delivered in 24–72 h when the item is available locally or at the supplier. The exact lead time is given in the quotation.

Can I replace an older Bernard actuator?

It can be checked, but we confirm a replacement only once we see the data. Send the actuator nameplate, the torque, the mounting flange, the voltage and a photo of the control. We look for the current range that keeps the existing connection and signals, then confirm in the quotation.

What information should the request for an actuator contain?

Specify the valve type (butterfly, ball, globe or gate), the torque or force required, the operating time, the voltage, the environmental protection and whether explosion-proof or SIL is needed. If the actuator replaces an existing one, attach its nameplate. Also mention the ambient temperature at the installation site.

How do I request a Bernard Controls quotation?

Send the Bernard Controls code from the nameplate and the quantity; we reply in English with availability and the lead time written in the quotation.
