#rb3-0178

The ASCO RB3-0178 is a direct-acting 24V DC poppet solenoid valve designed for precise control of fuel gas flow in HVAC systems. The valve utilizes a small, disc-shaped poppet that opens and closes an internal passage in response to an electrical signal. When energized, the solenoid creates a magnetic field that lifts the poppet, allowing fuel gas to flow. De-energizing the solenoid removes the magnetic force, and the poppet spring closes the passage, stopping gas flow.
