Dayton Air Control Products
Ridewell Suspension stopped manufacturing the Model 7423 Height & Leveling Control Valve around 2006. This Valve described as Mega-Duty was used on Trucks/Tractors, Trailers, Buses, Motor Homes, Air Cabs and Air Seats.
The Valve was available in many configurations and under numerous Part Numbers. It also came in an Air Dump Valve version, where a Dump Valve was mounted to the top of the Height Control Valve.
This Valve is recognizable with a black plastic body and distinctive blue exhaust cap on the bottom and the Ridewell name and numbers 7423 molded into the top of the valve near the air supply port.
Depending on your particular application there are several good replacements that we can recommend for you below. Please note that with any replacement some changes may be required during installation.

K861007 - If you have a "7423 with a Zero Pressure Dump" such as a Trailer that uses automatic dump then this is a good choice. It comes with 3/8" PTC fittings and may require re-routing the air lines.
