Opciones de personalización

We offer stainless steel, cast aluminum and engineering plastic housings to adapt to corrosive, humid and dusty conditions. It enhances weather resistance and structural strength for long-term stable operation in various explosion-proof zones.

Multiple AC and DC voltage grades are available, covering common industrial low and medium voltages. It complies with domestic and international power supply standards to connect with all kinds of industrial control circuits.

Wall-mounted, column-mounted, embedded and floor-standing structures are optional to optimize on-site layout and fit workshop equipment, pipelines and control cabinets.

IP54 to IP66 protection levels are customized to resist rain, dust and oil pollution. It is ideal for outdoor ports, open oil fields and underground coal mines.
L(B/C/N)Z Series Explosion-proof Operating Column
L(B/C/N)Z series explosion-proof operation columns are major on-site control devices for high-risk industrial automation in petroleum, chemical and coal explosion-prone areas. Made of high-strength materials, the dustproof, waterproof and anti-corrosion columns support multi-module combination. With simple operation, they realize quick device start-stop and status checking. Customizable explosion-proof grades and installation methods fit layouts of various automated production lines.


BZX51 Explosion-proof Travel Switch
Long-term high-load operation of automated equipment requires durable limit switches. BZX51 switches adopt wear-resistant contacts and reinforced housings with anti-vibration and anti-aging performance, rarely failing after repeated triggering. Dustproof and waterproof, they work stably in dusty and humid conditions. Replacing old switches reduces maintenance downtime and cuts operational costs of production lines.
BDF Explosion-proof Solenoid Valve
BDF explosion-proof solenoid valves adopt modular structure and standardized parts for convenient maintenance and component replacement without disassembling whole pipelines. The wear-resistant spools resist jamming and reduce failures. Widely used in oil depots, chemical lines and coal mine ventilation pipelines, they simplify on-site maintenance while ensuring explosion-proof safety and improving overall production efficiency.


General Explosion-proof Travel Switch
The general explosion-proof travel switch has strong universality for automated equipment in most regular explosion-prone areas such as ports, metallurgy and grain processing. Equipped with complete limit and interlock functions and standard installation sizes, it replaces many similar products directly. Dustproof and waterproof with high cost performance, it is an ideal universal choice for equipment explosion-proof renovation and regular part replacement.
AC Series Explosion-proof Plug-in Device (IIB)
AC series explosion-proof plug devices (IIB) are designed for IIB explosion environments, providing temporary power for mobile automated equipment and testing instruments. The sealed explosion-proof structure avoids exposed electric arcs during plugging. Firmly connected and anti-drop, waterproof and dustproof, they fit indoor and outdoor explosion-proof scenarios such as ports and chemical workshops, becoming standard safe parts for temporary power use.

Explosion-proof Control Components Secure Hazardous Industrial Automation


In industrial sites like petroleum and chemical plants with flammable and explosive media, common electrical parts easily cause safety accidents, making professional explosion-proof control components essential for automated production. Tovent’s five core products cover operation, limit, valve control and connection, complying with domestic and international explosion-proof standards. After multiple tests, the products adopt sealed housings and flameproof circuits to isolate sparks from dangerous media. Many factories have reduced failure rates and simplified safety management after replacement.
The upgrading of industrial automation relies on the iteration of supporting explosion-proof equipment. Many old factories use outdated parts with poor precision and declining protection, leading to hidden dangers. With years of experience, Tovent optimizes products based on on-site operation, selecting proper materials and wiring for actual working conditions. These products fit both fixed and mobile equipment. We also provide personalized customization on explosion-proof grades and installation sizes to match all automated production lines.
