Co-ax Flow Control Valves

Within the family of pressureregulating valves, a technical distinction is made between series of bypass valves, inline valves and threeway valves.

Coaxial highpressure valves are valves with two or three connections and two switching positions. The pneumatically operated valves of the VK series in particular have an extraordinarily positive relationship between high pressure range and high flow rate due to their high switching force.

The cartridge valves are available in a nominal width of 10 to 15 mm. Depending on the pressure difference, drives with one, two, or three pistons are required. The tedious dismantling of the entire valve body from the pipeline using a large wrench is no longer necessary; only the three screws have to be loosened. Another advantage is the consistently small valve diameter, even at the highest system pressures. The drives have small diameters and are arranged in tandem, one behind the other. This means that these valves can be installed next to each other to save space, even in extremely confined spaces. A version with a hose seal is available for heavily soiled or sticky media.

Whenever several valves are to be used in a confined space and with minimal piping, a module or strip solution is recommended. In contrast to single piping, the expense for valve piping, fittings, working time, and possible leaks is almost cut in half.
