KP BACKFLOW PREVENTERS
The NavoTech KP backflow preventers are used for one-way closing and opening of pipe channels, preventing backflow in the event of a rise in the level of sewage behind the flap. They play a protective and regulatory role.
The backflow preventer opens automatically in the direction of flow due to the pressure of the liquid inside the pipeline.When the liquid pressure rises downstream of the non-return check valve (in the receiver) to a value greater than the pressure in the supply pipeline, the non-return flap closing disc is automatically closed.
The KP backflow preventers are manufactured in two basic types:
-network backflow preventer,
KP-S - backflow preventer, network, barefoot,
KP-Sk - backflow preventer, network, flanged,
for installation on a gravity sewer network,
- final backflow preventers
KP-Kb - backflow preventer, final, barefoot,
KP-Kb-p - backflow preventer, final, barefoot with counterweight,
KP-Kk - backflow preventer, final, flanged,
KP-Kk-p - backflow preventer, final, flanged with counterweight,
for installation in a well, abutment, sewage outlet to the receiver.
