A pump discharge valve is necessarily a Butterfly valve fitted on the discharge side of the pump which acts as both a non-return valve and an isolation valve.

Its main function is to prevent the reverse flow of water in the event of pump shutdown.

For large pumping schemes, the pump discharge valve is a cost-effective solution compared to installing a separate isolating valve and non-return valve on the pump outlet. Owing to its Butterfly type construction, it offers high flow capacity and low head loss (pressure drop), significantly reducing pumping energy consumption on a continuous basis.

Recognized as a breakthrough in modern pumping design, the Butterfly type pump discharge valve has been widely adopted in lift irrigation projects, which are among the largest users of centrifugal pumps.
