DN25/32 drain service valve with socket ends AVK

Drain service valve, primarily intended for use in summer house areas where the pipeline depth is shallow or where there is a need to drain the house's plumbing system for the winter.
The ground tap is equipped with a valve that remains closed under pipeline pressure, but when the pressure drops, a membrane opens, allowing the pipeline to drain into the ground.
The product comes with a drainage pipe that attaches to the valve.
