The Cla-Val 585 Series Swing Check Valve is designed for long service life and maintenance-free operation. It has a full-flow area body and is equipped with a disc arm with dual precision pins for optimum disc connection and protection against damage due to vibration.
During system flowing conditions the disc swings up to the open position allowing unrestricted flow through the valve. When system reverse flow conditions occur, the disc swings down to the closed position, preventing reverse flow. This product is available in sizes 2″ through 48.”
