Siemens Building Technology 274-03080 Control Valve Assembly 319825-402 The Reznor 209339 Spark Electrode

The Reznor 209339 Spark Electrode (also identified as PSE-RZ9) is the direct OEM replacement engineered to deliver consistent high-voltage arcing to ignite the gas-air mixture across various unit heater and air handler platforms

Precision Pilot Duty: Optimized for low-volume pneumatic circuits to ensure stable and responsive actuator control

The Johnson Controls VG2231VM292NGGA is a heavy-duty 4-inch 2-way normally open flanged globe valve designed for precise flow control in demanding hydronic systems

though it provides functional insulation only in these setups

which often results in the motor "hunting" (rocking back and forth)

Siemens Building Technology 274-03080 Control Valve Assembly 319825-402 The Reznor 209339 Spark ElectrodeThe Siemens 274 03080 Control Valve Assembly is a heavy duty solution for precise hydronic flow control in commercial HVAC systems. This 2 way normally closed modulating valve features a 2 inch NPT connection and is engineered with a 40 Cv linear flow characteristic to ensure stable regulation in air handling units and heat exchangers. Designed for seamless integration, the Siemens actuator accepts both 0 10 VDC and 4 20 mA control signals, operating
