TROX Explosion Proof Actuators

Product Information

Specifications

• Product Name: Explosion-proof Actuators
• Application: Opening and closing multileaf dampers in potentially explosive atmospheres (ATEX)
• Optional Equipment and Accessories: Solenoid valve (24V or 230V), Limit switches
• Material: Construction and materials comply with EU directive and guidelines for use in potentially explosive atmospheres (ATEX)

Description

• The Explosion-proof Actuators are designed for opening and closing Type JZ and JZ-Low leakage multileaf dampers in potentially explosive atmospheres (ATEX).
• They are suitable for use with steel or stainless steel multileaf dampers that have brass or stainless steel bearings.

FAQ

What is ATEX?

• ATEX stands for “Atmosphères Explosibles” and refers to the European Union directive that covers equipment and protective systems intended for use in potentially explosive atmospheres.

What zones are the actuators approved for?

• The actuators are approved for gases, mists, and vapours in zones 1 and 2, as well as dusts in zones 21 and 22.

What is the control input signal for the electric actuators?

• The control input signal for the electric actuators is a 2-wire control (3-point, open/close).

How can I manually operate the electric actuators?

• The electric actuators come with a crank handle for manual operation.

Product Using Instructions

Special Characteristics

• ATEX mark and certification
• Approved for gases, mists, and vapours in zones 1 and 2
• Approved for dusts in zones 21 and 22

Electric Actuator

• Overload protection
• Control input signal: 2-wire control (3-point, open/close)
• Spring return actuator for damper blade safety function
• Auxiliary switch for capturing the end positions
• Crank handle for manual operation

Pneumatic Actuator

• Control input signal: 1-wire control of a solenoid valve
• Optional limit switch for capturing the end positions
• Safety function with double acting actuators (power off)
• Safety function with single acting actuators (pressure off)

Functional Description

• The Explosion-proof Actuator moves the blades of a multileaf damper into the OPEN or CLOSED position.

Electric Spring Return Actuator

• Control input signal with 2-wire control (3-point).

Double Acting Pneumatic Actuators

The easiest way to generate the control input signal is electrically, using solenoid valves. The multileaf damper is opened and closed with compressed air. The actuator has two tube connections. Compressed air is applied to one tube connection while the other connection remains open, allowing the air to escape from the corresponding chamber of the actuator. For the other direction of rotation, the process is reversed.

Single Acting Pneumatic Actuators

• The easiest way to generate the control input signal is electrically, using solenoid valves.
• The multileaf damper is closed with compressed air and opened with spring force. The actuator has one tube connection for compressed air. For the other direction of rotation, the connection remains open.
