Caleffi Series 8541 Normally Open Threaded Gas Solenoid Valve with Manual Reset
PGTECH is the official distributor of Caleffi products in Vietnam, supplying a comprehensive range of gas safety valves and hydraulic solutions imported directly from Italy. The Caleffi Series 8541 Threaded Gas Solenoid Valve is engineered for gas shut-off applications where maximum operational safety and reliable manual restart are required.
Operating in a normally open (NO) configuration, the valve automatically closes whenever electrical power is interrupted and remains closed until manually reset. This design prevents unintended gas flow after power restoration, making it ideal for gas burners, boiler rooms, commercial kitchens, industrial gas pipelines, and other gas safety installations.
Manufactured to stringent European standards, the Series 8541 combines durable construction, threaded installation, IP65 Class A Group 2 protection, and ATEX certification to deliver reliable long-term performance in hazardous environments.
Available threaded sizes include 1/2", 3/4", and 1", with actuator options for both 24V and 230V power supplies.
Main Features
The Caleffi Series 8541 enhances gas system safety by automatically isolating the gas supply during power failure while requiring manual reset before normal operation resumes. Its threaded connection simplifies installation, while IP65 Class A Group 2 protection and ATEX certification ensure dependable operation in commercial and industrial gas systems requiring high safety standards.
