German Auma valves Auma models Auma prices

Auma valves serve an on/off function. They are commonly installed at the inlets and outlets of cold and heat sources, at equipment inlets and outlets, and on pipeline branches (including risers); they can also be used as drain valves and air vent valves. Common shut-off valves include gate valves, globe valves, ball valves, and butterfly valves. Gate valves can be classified into rising-stem and non-rising-stem types, single-disc and double-disc types, and wedge-disc and parallel-disc types. Gate valves do not provide tight shutoff, and large-diameter gate valves are difficult to open; the valve body size along the flow direction is small, resulting in low flow resistance, and gate valves cover a wide range of nominal diameters. Globe valves are classified into straight-through, angle, and Y-pattern types based on media flow direction,
