Caleffi Normally Open Gas Solenoid Valve with Manual Reset – Series 8540

PGTECH is the official distributor of Caleffi products in Vietnam, supplying a comprehensive range of gas safety valves and hydraulic control solutions imported directly from Italy. The Caleffi Series 8540 Normally Open Gas Solenoid Valve is specifically designed for gas shut-off applications where manual reset after a power interruption is required to enhance operational safety.

Operating in a normally open (NO) configuration, the valve automatically closes when electrical power is lost and remains closed until manually reset. This design helps prevent unintended gas flow after power restoration, making it particularly suitable for gas burners, boiler rooms, industrial gas pipelines, and commercial gas distribution systems.

Manufactured to stringent European standards, the Series 8540 offers reliable performance, robust construction, IP65 environmental protection, and ATEX certification for installation in potentially explosive atmospheres.

Main Features

The Caleffi Series 8540 gas solenoid valve enhances gas system safety by automatically shutting off gas flow during power failures while requiring manual reset before restarting operation. This safety mechanism minimizes accidental gas release after power restoration and provides greater protection for personnel, equipment, and industrial facilities. Its rugged construction, ATEX certification, and reliable operation make it suitable for demanding commercial and industrial gas applications.
