Arflu tilbakeslagsventil for dyse

Beskrivelse

Arflu Nozzle tilbakeslagsventiler er utviklet for å gi pålitelig forebygging av tilbakestrømning for petrokjemisk industri, gass- og vannforsyning.
Arflu’s Engineering department has create Nozzle check valve with dymanic quick closing which reduces the flow return speed. The Axial movement of the disc produces a streamlineflow with venturi effect which reduces the pressure drop with minimal seat leakage and with minimum turbulences.
Our design needs only a very low flow to completely open the valve and guarantees the highest fluid dynamic performances reacting fast to flow alteration.
Arflu Nozzle check valves are available with multiple spring torques increasing considerably its purposes. it has also been conceived to have a really low maintenance costs and high serviceability.

DYNAMIC QUICK CLOSING
Arflu Nozzle Check valves are design to reduce the fluid flow speed during the closure.

MAINTENANCE AND SERVICEABILITY
Arflu valves are designed and developed to have the lowest possible maintenance. If any repair is required, these can easily be accessed without any special tools.

FLUID HAMMER REDUCTION
Thanks to its special design of the disc there is an important fluid hammer reduction which also depends on the spring torque.

DISC AXIAL MOVEMENT
The inner shape produces a streamlined flow with Venturi effect which reduces considerably the pressure drop.

DISC SHORT STROKE
All of our Nozzle check valves are developed to have a short stroke of the disc which also means a reduction of the body dimensions which also signifies less material needed.
