ASCO NF8551B405 Hazardous Location Solenoid Valve

ASCO NF8551B405 Hazardous Location Solenoid Valve is a pilot-operated valve designed for use in hazardous-area environments, featuring 1/4" NPT inlet and outlet connections and a 24 VDC coil. This model is part of ASCO’s NF8551 family, intended to control gas and vapor flows in industrial plants where strict safety classifications apply, such as chemical processing, oil and gas, and refining facilities. The valve offers a compact, rugged design with an orifice around 0.24 inches (approximately 6 mm) and a moderate flow capacity suitable for differential pressures up to roughly 30 psi, depending on installation and media. It is built for integration with standard control circuitry and is suitable for safety-critical gas-handling and automation applications in demanding hazardous-location environments.
