The VATTEN explosion-proof limit switch model V274 valve limit switch box is an essential field instrument for monitoring valve status in an automated control system. It outputs a switch signal indicating the open or closed position of the valve. This signal is received by the controller or sampled by the computer for verification, which then triggers the next step in the process. In addition to valve status monitoring, this device plays a critical role in valve interlock protection within the automated control system and provides remote alarm and indication functions, ensuring the safe and reliable operation of the system.

|
Universal AC/DC Compatibility |
Silver-plated contacts to prevent poor contact due to copper oxidation. |
|
Display Cap |
Made from impact-resistant, high-transparency polycarbonate, maintaining clarity even outdoors (compared to AS or acrylic used in some market products). |
|
Surface Layer |
Outdoor-specific epoxy resin, resistant to fading or peeling over time. |
|
Materials |
Stainless steel used for all components (shaft, screws, brackets) to ensure high product quality. Market products may have thinner walls and cheaper materials like UNIWO’s 1/2 thickness, fast-cutting iron shafts, or zinc-plated screws. |
|
Shaft and Shell |
Copper sleeve for good gloss and tight sealing between shaft and outer casing. |
|
Explosion-Proof Switch |
Wall thickness ≥ 4.5mm, meeting explosion-proof research institute standards. |
|
Certifications |
Waterproof and explosion-proof certifications. |
|
Internal Protection |
Corrosion-resistant treatment and color coating applied inside the switch. |
|
Casting Material |
ADC12D for the body material. |
We can design and develop according to the needs of our customers to meet the requirements of different clients.

One-stop Automatic Valve Solutions Though small in size, valves act as the critical "throats" in the industrial chains of coal chemical and mineral processing sectors. The fluids here are far from pure — they consist of ore slurry loaded with high-hardness particles, highly corrosive chemical agents, as well as high-te...
