ARPModel CO-L20 Series -Double Offset Valve

SHARE

Double offset dampers are widely known as high performance valves. Particularly suited for low pressure flows, total tightness requirements and temperatures up to 260°C. Tightness is guaranteed by perfect coupling of the self-adjusting gasket inserted on the perimeter of the blade and the stainless steel seat. Robust design and high-quality materials ensure long life, low operating torque values and low friction. Double eccentric valves are leak-proof in one direction only. Flow direction is indicated by the arrow. Hydrostatic tests are performed as standard according to EN 12266.
