  • Ball drain wye strainer valve assembly
    Patent number: 11802625
    Abstract: A ball drain wye strainer valve assembly includes a wye strainer located adjacent to a T-ball valve within a unitary body. The ball drain wye strainer valve assembly includes an additional valve member. The combination of the valve members permits the flushing of the wye strainer screen from either upstream or downstream. A drain is also incorporated to allow for the system draining, flushing, or air-purging during the initial installation and subsequent maintenance of the screen and wye strainer.
