Description
The control valve ZK 313 is used to reduce large differential pressures. It is used mainly in
industrial plants and power stations in which ease of maintenance and high resistance to
wear are required.
The valve consists of the valve body, a yoke suitable for the various actuators, and a ZK
radial stage nozzle

with valve plug integrated in the valve body to act at the control element.
The valve body comes in two different sizes: The small size DN 25 - DN 80 is available as
straight-through (ZK 313-D/...) or angle (ZK 313-E/...) version. For larger flowrates open-die
forged bodies DN 80 - DN 150 in Z shape (ZK 313-Z0/...) or as angle versions (ZK 313-E0/...)
are also available.
The control valve can be operated by means of various actuators, e.g. electric rotary
actuators, pneumatic actuators and lever actuators, or by means of a handwheel.
