Both models are double check detector assemblies. Production of the Model 16 was from approximately 1980-1990. The Model 16-4 began in 1991 and was discontinued in 2003. In the Model 16 the main valve utilizes an assembly similar to the Model D/DEX. The bypass valve on both models utilizes the 3/4" D2 or Wilkins 950 XL. The serial number of the main valve unit is needed to order some repair parts. The Model 16-4 main valve utilizes the D-4 design.
