Explosion-Proof Electric Actuators are a great choice for use in hazardous gas or dust environments. These units feature flameproof enclosures and conduit seals that prevent heat and sparks.
They also come equipped with a hand wheel for manual control. They are ideal for automating quarter turn ball valves, butterfly valves and dampers.
- Safety
Designed for environments with hazardous gas and dust, explosion-proof electric actuators provide safe valve automation. They are certified to UL, ATEX and IECEx standards for safety in oil/gas, chemical/pharma and other facilities handling combustible materials. They feature flameproof enclosures, conduit seals and dual power shaft seals to prevent sparks during an explosion.
They include overload, temperature and torque switch protection, visual and electrical valve position indication as well as manual override. They can also be fitted with a variety of angular travel changeable mechanisms to suit your application.
The most important performance metrics for actuators are speed and durability. The former refers to the actuator’s speed capacity when it’s not carrying any load, while the latter is its ability to withstand extreme conditions.
- Durability
Whether you need on/off, jog, or proportional control, explosion-proof electric actuators are built to last. The RuggedBoard design reduces internal electrical connections, locking drives eliminate the need for motor brakes and manual override does not require a clutch, making them the most durable actuators available. Failsafe options are also available to ensure your system reverts to a safe position in case of failure.
The WE Series and XE Explosion-Proof electric actuators are specifically designed for quarter turn operating applications such as Ball valves, Butterfly valves, Plug valves and Dampers. With a hard aluminum alloy housing, anodized with polyester powder coating, these units offer durability and corrosion resistance.
All models are ISO 5211 compatible with double square drive and include visual valve position indicators and manual override without a clutch or brake. They are designed for Zone 1 or 2, containing Group II A and Group II B gases, or Zone 21 or 22, containing combustible dust atmospheres with temperatures up to T4. Suitable for Water-treatment plant, Petroleum, Pharmacy, Chemical industry, Power Plant, Metallurgy etc.
- Efficiency
Electric actuators do not require pumps or motors which are exposed to the elements, which makes them more reliable. They are also quieter than pneumatic or hydraulic complete systems and don’t leak hazardous fluids. They can reset to a fail-safe position in the event of power loss and are ideal for remote environments like a gas pipeline powered by solar or battery.
They are also more efficient than other types of actuators. Their linear systems can reach up to 15 times the travel life of a ball screw solution and have a high level of control over position, acceleration or deceleration and output force compared to servo hydraulic solutions.
Group 57 Explosion proof electric actuators are great for hygienic applications, such as managing chemical dosing and flow management. They have a rugged construction and high reliability standards and run on DC power which makes them an excellent choice for remote, hazardous environments. They are equipped with a spring-return failsafe option which means that in the event of a power failure, the valve will be reset to a preset, safe position.
- Convenience
In addition to their safety and durability features, explosion-proof electric actuators are convenient because they don’t require external pumps or motors. This means they are smaller and take up less space than traditional hydraulic actuators.
These actuators are also able to work in hazardous and flammable environments because they are designed with flameproof enclosures and conduit seals that prevent sparks. They are also UL, ATEX and IECEx certified to ensure that they perform well in a wide range of conditions.
In addition to explosion-proof features, these actuators are equipped with intelligent functions like bus control technology, absolute encoder, infrared remote control technology and liquid crystal display. This makes them ideal for use in a variety of industrial applications. They can also be used with a wide variety of valves including ball valve, butterfly valve and gate valve. This allows you to realize industrial automation and improve the safety of your project. It can be used in dangerous industries such as petroleum, paper, metallurgy and power plant.
