GLOBTOS P400-25 793 1,8<\/strong><\/p>\n

Ball valve for pre-insulation \u2013 reduced bore DN400 PN25<\/b><\/h2>\n

Compact valve solution for underground networks.<\/b> The GLOBTOS DN400 PN25 ball valve with wrench operation (hexagonal stem) for pre-insulated systems with reduced bore is an economical solution for underground district heating networks using dry stem technology.<\/span><\/p>\n

Key features of the DN400 valve<\/b><\/h3>\n

Dry stem \u2013 insulation protection<\/b><\/h4>\n

The special design with sealing located next to the ball eliminates the risk of flooding the pipeline insulation layer. This is crucial for maintaining thermal insulation performance and ensuring long service life of the entire system.<\/span><\/p>\n

Compact design<\/b><\/h4>\n

The reduced ball diameter allows for smaller valve dimensions, making installation easier in chambers and inspection wells. Lower weight also ensures easier handling during installation.<\/span><\/p>\n

Compatibility with pre-insulated systems<\/b><\/p>\n

The design compliant with EN 488 ensures full compatibility with pre-insulated pipelines. Standard dimensions allow seamless integration with existing infrastructure.<\/span><\/p>\n
