Normally Closed Diaphragm Gas Valve, 1 in. NPT

This normally closed diaphragm gas valve is for commercial heating equipment professionals who need to control gas flow and provide final shutoff service. It is designed for use with natural, LP, or manufactured gases in atmospheric boilers, commercial water heaters, and rooftop heaters.

The solenoid-operated valve has a cast aluminum, straight-through body with 1 in. NPT connections and a maximum pressure rating of 1/2 PSI. It operates on line voltage, opens slowly, and closes quickly through a weight- and spring-loaded diaphragm. The valve closes on power failure, with a maximum closing time of two seconds. Opening time can be set using various bleed-orifice sizes or an adjustable bleed valve.

Key Features:

• Normally closed operation: Closes when power fails to support final shutoff service.
• Slow-opening action: Allows the opening time to be set with compatible bleed-orifice options or an adjustable bleed valve.
• Fast closing response: Closes firmly in two seconds maximum.
• Gas compatibility: Supports natural, LP, and manufactured gas applications.
• Straight-through aluminum body: Provides a cast aluminum valve construction in a straight-through pattern.

Choose this 1 in. NPT diaphragm valve for line-voltage commercial heating systems that require normally closed gas control and final shutoff capability.
