At present, our Division 1 produces MODACT® actuators intended for the actuation of valves, also ball, butterfly and gate, of all types even in environments with gas or fume explosion hazard.
Wide range of types opens extensive application possibilities for our actuators in control and regulation circuits of technological processes.

Our manufacturing program includes rotary single-turn and multiturn actuators for direct mounting on valves or lever-type actuators with closing torques from 8 to 4000 Nm, linear actuators with axial forces from 11.5 to 63 kN.

Our special features are MOA and MOA OC actuators intended for operation under extreme conditions in nuclear power plants.

Modular concept of MODACT actuators made it possible to simplify and unify numerous actuator elements and to achieve long service life and high service reliability of these units. Contributor to this development was our own design and development base which gave rise to several unique solutions - epicyclic gear case design permitting manual actuation even with electromotor running, torque switch interlocking, low hysteresis and non-linearity of position transducers or high setting accuracy of position and torque switches.

Safe operation of our actuators is secured by enclosure of types IP 55, IP 65 and IP 67.

A new feature of our actuators is electronic circuitry with microprocessors allowing higher actuation accuracy and higher plant reliability to be achieved with less demanding commissioning and adjustment operations. This circuitry is also equipped with permanently operating self-diagnostic facility, which greatly simplifies fault detection in control circuitry.

Commercial designation of these actuators is MODACT CONTROL. Greatest care is dedicated to quality control in all phases of production because quality is one of the most important aspects influencing market success of the product.

This is why we decided to introduce a quality control system in all activities of our company. Culmination of this effort was successful certification audit and acquisition of EN ISO 9001 Certificate from RW TÜV Institution in Essen in March 1995. Renewal audit in 2006 was successful and validity of the Certificate was prolonged until 2009. These were the first steps in our effort the objective of which is a reliable product and, consequently, a satisfied customer.

We provide guarantee and postguarantee services for our products. We offer the following services: installation of actuators on customer premises, adjustment, repairs, adaptations, revisions and external maintenance.
