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.
