DN50-DN200 Plastic Ball Valve Lockout
DN50-DN200 plastic ball valve lockout device BD-F02 is a professional industrial lockout & tagout (LOTO) system energy isolation device, primarily used for handle-type ball valves with diameters ranging from DN50 to DN200 (50 mm to 200 mm).
- Compatibility Range: Designed specifically for DN50-DN200 (50mm-200mm) handle-type ball valves. The adjustable structure adapts to standard ball valves of different sizes within this range.
- Material Specifications: Made of high-strength PP engineering plastic in one piece, impact-resistant, corrosion-resistant, and aging-resistant, it can operate stably under complex conditions such as extreme temperatures from -20℃ to 100℃.
- Locking configuration: Supports simultaneous locking operations using two industrial safety padlocks with a shackle diameter ≤ 9mm, with team collaborative maintenance, strictly adhering to the “last person to unlock” safety standard, effectively avoiding the risk of mis-locking by a single person.

Core Selling Points:
Adjustable Design: Compatible with pipe diameters of 64mm–100mm (2"to 8"), suitable for most industrial ball valves. A single model covers multiple valve specifications, significantly reducing inventory costs for businesses.
Four-Legged Wrap-Around Design: Four legs tightly wrap around the valve body and handle, ensuring a more secure and slip-resistant lock, preventing accidental loosening during maintenance.
High-Strength Engineering Materials: Made of impact-resistant, aging-resistant, and high/low temperature resistant engineering plastics, suitable for long-term use in harsh environments such as chemical plants, oil fields, power plants, and manufacturing workshops.
Multi-User Lockout Management: Supports simultaneous locking by multiple users, complying with the "last person to unlock" safety standard for team maintenance, improving on-site management compliance.
Visual Identification: High-recognition industrial safety color scheme allows for easy identification of the locked status from a distance, effectively reminding personnel to refrain from operation and reducing the risk of accidents.
- Quick Installation: Tool-free installation and disassembly; locking/unlocking can be completed with one hand, improving maintenance efficiency and adapting to high-frequency LOTO (Locking On to Move) operation scenarios.
- Wide range of applications: Suitable for all industrial scenarios requiring energy isolation, including petrochemicals, power generation, pharmaceuticals, papermaking, shipbuilding, and mining.
- Safety and compliance: Product structure and performance comply with CE and OSHA standards, helping companies pass EHS audits and reducing compliance risks.
