ASCO JB8214235CSA 2-Way Normally Closed 3/4″ NPT 120VAC Fuel Gas Solenoid Shutoff Valve

Description

ASCO JB8214235CSA Fuel Gas Solenoid Shutoff Valve Overview

The ASCO JB8214235CSA is a 2-way, normally closed solenoid valve engineered for reliable fuel gas shutoff applications in commercial and industrial HVAC systems. With a robust aluminum body, NBR seals, and a NEMA 1 enclosure with junction box, this valve delivers dependable performance and straightforward installation in demanding environments.

Key Features

• 2-Way, Normally Closed (NC) operation — valve closes automatically upon de-energization for fail-safe fuel shutoff
• 3/4″ connection — compatible with NPT or Flange pipe configurations for flexible installation
• 120VAC coil voltage for standard commercial electrical supply compatibility
• Flow coefficient (Cv) of 11 — supports up to 593,200 BTU/hr fuel gas capacity
• Operating pressure range: 0–5 PSI, ideal for low-pressure fuel gas systems
• Aluminum body construction — lightweight, corrosion-resistant, and durable
• NBR (Nitrile Butadiene Rubber) seals — excellent compatibility with natural gas and other fuel gases
• NEMA 1 enclosure with junction box — suitable for general indoor use, protecting internal components from dust and light contact
