摘要： A valve device incorporating two valves is provided. For example the two valves could be a stop valve and a control valve, housed in the same side of a common casing. The proposed valve device includes an inlet port and an outlet port connected by a fluid flow channel. The valve device further includes a first valve and a second valve housed in a common casing. The first valve includes a first valve head mounted on an annular-shaped first spindle. The second valve includes a second valve head mounted on a second spindle, the second spindle extending concentrically and slidably through the annular-shaped first spindle. The first and second valves are displaceable along a common axis and operable to influence fluid flow between the inlet port and the outlet port through the flow channel.
