German INSECA valve INSECA model INSECA price

INSECA 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 as rising-stem or non-rising-stem, single-disc or double-disc, and wedge-gate or parallel-gate. Gate valves do not provide tight shutoff, and large-diameter gate valves are difficult to open; the valve body dimensions along the flow direction are small, resulting in low flow resistance, and gate valves cover a wide range of nominal diameters. Globe valves are classified by medium flow direction into straight-through, angle, and Y-pattern types.
