Notice the difference between the 2 different clamps. Parts #11 and #12. These will determine which valve you need. Clamp style part #11 is WVS002. Clamp style part # 12 is WVS003. These valve look similar but are NOT interchangeable. Several of the internal parts of the valve are the same. All parts are available at http://www.waterwayparts.com
