A Y Mcdonald 4215-194 Low Pressure Plug Valve 3/4 in Fnpt Brass

Product Description

The A Y MCDONALD 4215-194 is a manually operated, low pressure plug valve with integral check, designed for natural gas and propane gas service on residential and light commercial house piping systems. The brass body construction suits indoor installations between the meter outlet and the appliance inlet connection. Rated at 2 psi, it accepts 3/4 inch FNPT connections and is operated by a lever handle actuator for quick quarter-turn shutoff. This valve is built for licensed plumbers and gas fitters performing appliance hookup or service work on low-pressure gas piping systems.

This valve is intended for indoor gas piping installations at ambient temperatures between 32 degrees F and 125 degrees F. It is positioned in the gas supply line between the meter outlet and the inlet connection of the gas appliance, making it a standard component in residential gas rough-in and service work. The integrated check function adds a layer of backflow prevention within the same body, reducing the number of fittings needed in the assembly.
