Abstract
Disclosed is a valve device and a method for operating at least two valves actuated by an actuator and arranged for controlling fluid flow in at least two separate fluid lines. The valve device can simultaneously control at least two diaphragm operated valves using a single actuator. The valve device includes a pressure release mechanism constructed to change pressure in a diaphragm chamber of each diaphragm operated valve and thereby open or close the diaphragm operated valve.
