Product description Control valves control gases, vapours or liquids and change the
flow conditions of a process.
The control valves consists of the body (valve bottom) and the
actuator which, depending on the control signal, changes the
position of the closure member (plug) relative to the seat. The
bodies have been arranged in logical kits, allowing the user
to assemble the highest possible number of variants from a
minimum of components to match each individual application.
Our range also includes a series of peripheral units such as
positioners, boosters, filter-reducing stations or solenoid valves.
Positioners and solenoid valves can be assembled directly or
according to NAMUR recommendations. Refer to the relevant
manufacturer’s instruction manual for information regarding
peripheral equipment.
