specifically engineered to regulate airflow and maintain consistent branch line pressure for pneumatic thermostats and HVAC zoning accessories

The unit is constructed with a porous bronze sleeve or high-grade steel balls (depending on specific revision) to minimize mechanical friction and thermal buildup during continuous duty cycles

this is a synchronous drive model

providing precise safety limit control for gas-fired equipment

it effectively manages individual loads up to 140

Carrier LH33WZ019 Ignitor Assembly 340155-7024 specifically engineered to regulate airflowThe Carrier LH33WZ019 Ignitor Assembly is a critical OEM replacement component designed for precise ignition sequences in Carrier, Bryant, and Payne gas fired furnaces. This hot surface ignitor (HSI) is engineered with high grade silicon carbide to withstand rapid thermal cycling and high temperature environments. It functions by reaching necessary ignition temperatures via electrical resistance before the gas valve opens, ensuring a reliable flame
