Hydraulic cylinder

Characterized by their long service life.

This is guaranteed by using of high-quality materials for guide and sealing elements.

Cylinder design:

Synchronous cylinder
Differential cylinder
single or double acting
with or without spring return
Optionally with position feedback and limit switches

Our position measuring systems are non-contact according to the state of the art. Hydraulic cylinders in special designs are also part of our delivery program.

Hydraulic cylinder

Type CD 250 C …. DBUW (nominal pressure 250 bar)

Application:

Hydraulic actuation of a control valve

Execution:

double-acting with end position damping in both directions
with a position indicator (magnetostrictive position measuring system)
with 2 pieces non-contact limit switches (initiators)
with a terminal box (position measuring system and limit switches are wired up to there.)

Hydraulic cylinder

Type CER 250 C …. DVUW (nominal pressure 250 bar)

Application:

Hydraulic actuation of a control valve with safety quick closing function

Execution:

single-acting with end position damping in CLOSE position (piston rod extended)
with a position indicator (magnetostrictive position measuring system)
with a terminal box (position measuring system is wired up to there.)
with a spring cylinder with built-in and preloaded disc spring package (for a quick-closing function)

Hydraulic cylinder

Type CER 250 C …. DVUW (nominal pressure 250 bar)

Application:

Hydraulic actuation of a steam reducing valve with safety quick closing function

Execution:

single-acting with end position damping in CLOSE position (piston rod extended)
with a position indicator (magnetostrictive position measuring system)
with a terminal box (position measuring system is wired up to there.)
with a spring cylinder with built-in and preloaded disc spring package (for a quick-closing function)
with an oil drip tray (for horizontal installation)

Hydraulic cylinder

Type CER 250 C …. DV (nominal pressure 250 bar)

Application:

Hydraulic actuation of a shut-off valve

Execution:

double-acting with end position damping in both directions

Hydraulic cylinder

Types CER 250 C …. DV and CD 250 C …. DBUW (both: nominal pressure 250 bar)

Application:

Hydraulic actuation of a combined shut-off and control valve

Execution:

single-acting with end position damping in CLOSE position (piston rod extended) for the shut-off valve (on top in the picture), equipped with 4 mechanical limit switches, with a spring cylinder (a pre-loaded disc spring package is installed for the quick-closing function) and with an oil drip tray (for vertical installation)
double-acting with end position damping in both directions for the control valve (on the right in the picture), equipped with a position indicator (magnetostrictive position measuring system)
Each of the both hydraulic cylinders is equipped with a control block with all the components which are necessary to control the hydraulic cylinders.
Additional, each of the both hydraulic cylinders is equipped with a terminal box to which all electrical components are wired.
