  • C300 / C300N / LFC300 / LFC300N

    C300 / C300N / LFC300 / LFC300N

    Ames C300 is a double check detector assembly. Originally produced under the Hunter name from 2000-2002. In 2002 Watts bought the Hunter models and began producing them as the Ames C200 and C200A. Watts also produces these models under the Watts name as the model 757 or 757A. The "C" designation refers to Ames Colt brand name. The body is stainless steel tubing. To access the check components a sleeve is mounted over the access cover. On the 2 1/2"-6" sizes the sleeve slides over the body to access the check components. On the 8"-10" sizes the sleeve is attached by two grooved couplings. The checks are modular and constructed of Noryl plastic. The check utilizes a torsion spring which is contained when the check module is removed from the body. The check spring must be extended and controlled with a pin or screw driver to replace the check disc. The check disc is either an EPDM or silicone. The model Ames C200 and Ames C200A will have the same external dimensions. The "A" model was discontinued in 2008 and utilizes a bi-link check mechanism while the "non A" version utilizes a tri-link check mechanism. The body length may vary and could be 1" shorter than shown in the dimension chart on versions produced earlier than 2003.

  • 3000SE

    3000SE

    The Ames 2000SE and 3000SE are double check valve assemblies. Production began in 1990. The body is fabricated stainless steel. Single top mounted cover. All have a modular check design. The 3/4"-2" from 1990-1992, had internal check mechanisms that were modular and made of a glass filled Noryl. The older assemblies have ball valve shutoffs that were built into the body. In 1992 external ball valves that screw onto the body of the assembly were added. In 1992 the check module working mechanism design was changed to a pivot design. 3/4" - 2" discontinued in 1997. The 2 1/2 - 12" check mechanism is made of a glass filled Noryl. The checks are modular. The check design is a cam operated mechanism. 2 1/2" - 10" sizes the check modules are not repairable and the whole check module must be replaced. For the 2000 SE design in the 2 1/", 6", and 8" sizes. The SE uses internal parts one size smaller than the pip size: 8" 2000 SE has 6" check modules, a 6" 2000 SE would contain 4" check modules. Be sure which version you have. The 2 1/2" SE was discontinued in 2003. The 6" and 8" SE models were discontinued in 2006.
