RK 007M3 CK1 3/4" 1st Check Complete

Series 007 Double Check Valve Assemblies are Watts "contractor grade" double check valve. They began production in 1989 and still are being manufactured. Available in sizes 1/2 - 3" all models feature a one cover design. The smaller 1/2 - 2" models are all constructed of bronze and use check modules that slide into the body and are held in place with a retainer. The modules come apart for service. Over the years, Watts has redesigned the devices slightly. They call these changes "modifications." You will notice devices tagged with 007, 007M1, 007M2, and 007M3. The "M" stands for modification and although the appearance is very similar on all these valves, their parts are very different, so be sure of your valve before ordering. The larger 2 1/2 - 3" devices are available in bronze or a cast iron epoxy coated body. Many different shutoff options and configuration options are available. Like the smaller sizes, they use self contained check assemblies with a retainer. For a short time, Watts offered a 4 - 6" 007 that discontinued in 1992. No special tools are required for servicing 007 Series devices
