Klapa przeciwcofkowa PTK-A VAG HADE® Siedlisko skośne dla rurociągów grawitacyjnych do mocowania kotwami na gładkiej ścianie betonowej

Flap valve with slanted disk to ensure discharge of the medium above the water level. For mounting to even concrete walls with anchor bolts. Easy mounting due to low weight and absolute corrosion resistance due to the PE-HD material. Opens even at low differential pressure due to the low-resistance disk bearing. Ideally suited for gravity lines and for use in pumping stations.
