Key Features of ONIS LINE BLIND
ONIS LINE BLIND, an alternative to conventional spectacle blinds, helps improve safety and reduce labor requirements in plant maintenance.
・Reduces equipment downtime by up to 95%
ONIS LINE BLIND enables quick opening and closing operation by a single operator without the need for additional tools. This significantly reduces the workload involved in piping isolation, even at sites facing labor shortages, and contributes to improved plant operating rates.
・High safety and reliability
In December 2025, ONIS LINE BLIND successfully passed the high-pressure gas equipment test conducted by the High Pressure Gas Safety Institute of Japan (KHK). The product delivers excellent safety and reliability even under demanding operating conditions.
・D3B model: A piping solution designed to eliminate human error
The D3B model incorporates a patented safety device that prevents incorrect operation while the valve is open, thereby eliminating the risk of serious accidents such as opening the system while it is pressurized. By minimizing fluid loss, the model also helps reduce wastewater treatment costs while contributing to environmental protection.
