ARK2 Swing Check Valve
The ARK2 PFA lined swing check valve is available in sizes up to 16” NB / DN400 and is ideal for slurries with its unhindered flow path through the open valve. The valve features a tapered seat to aid with closing of the valve in horizontal lines. The valve body is a wafer pattern style and is sized to mount between ASME B16.5 class 150 and DIN PN10/16 flanged piping. Like other PFA lined valves from the Atomac range the ARK2 non-return valve utilises T grooves machined into the cast body to anchor the lining firmly to the body ensuring the integrity of the liner when the valve is operating at high pressures and temperatures.
