The TA Roloff range offers a wide array of options for modifying valve gear to the customer’s needs. If you do not wish to utilise these options and are looking for a simple 90° actuator (quarter turn) you might find what you are looking for with this brand.   Nurkraft actuators are a traditional and effective […]


TA Roloff actuators can be upgraded with the patented FM System to carry out spring operated fail-safe mechanisms. The typical application areas of the FM System are areas where valves must automatically move to prior determined safety positions (end position “OPEN” or “CLOSED”) in the event of a power failure. The FM System uses the  […]


E 71 Hilfsspannung TA Roloff actuators can be made fail safe with the E71 auxiliary power unit. This will ensure that actuators in operation will move to the required safety positions (end positions “OPEN” or “CLOSED”) in the event of a power failure. The energy from integrated accumulators is used for this purpose. The integration […]


IP 68 Oceangear The actuator series TA 70, TA 120, TA 130 and TA 140 are available in hermetically sealed casing (according to IP 68) for permanent underwater service for depths down to 100m. The IP 68 Oceangear Series is therefore the first choice for areas which are either permanently, frequently or occasionally flooded.  A […]


TA Actuator 140 Ex Ex II 2G Ex de IIC T6 (ATEX) An actuator for heavy and very heavy industrial applications. Works perfectly on plug valves and on valves with a high restoring torque. High performance margin provides safety. Advantages : Suitable for Zones 1 and 2 Device categories 2G and 3G Pressure resistant casing “d” […]


TA Actuator 140   An actuator for heavy and very heavy industrial applications. Even valves with a high restoring torque (e.g. metal to metal sealed butterfly valves) can be safely operated due to the self-locking gears. Advantages : High torque up to 1500 Nm Compact size (ideal for installing into systems) Simple electrical control Robust metal […]


TA Actuator 60 Ideal actuator for building into systems (e.g. fire extinguishing systems) or for automating high pressure needle valves.   Advantages:  High torque (min. 8 Nm) Compact construction (ideal for building into systems) Simple electrical control Robust metal casing Many options Highly suited for the pharmaceutical industry and for mounting onto laboratory valves. 


TA Actuator 130 Ex Ex II 2G Ex d IIC T6 (ATEX) Value for money for standard and heavy industry applications. They are, for example, ideal for valves requiring a high torque throughout their entire travels such as plug valves on ships carrying bitumen.   TA Roloff can offer  this model with all custom designed options […]


TA Actuator 130 Actuator with a very good price/performance ratio and a wide range of applications for medium-heavy and heavy industry. Ideal for valves requiring a high torque over the entire travel e.g. plug valves or ball valves carrying dry steam. Advantages : High Torque (up to 280 Nm) Compact construction Simple electrical control Robust metal […]


TA Actuator 120 The basic underlying construction of this actuator has not changed for decades. It is frequently used in shipbuilding where mounting space is limited. It is a robust alternative to cheaper actuators with their high maintenance costs. Harmonic proportions of actuator and valve up to a torque range of DN 125. Speeding up […]


TA Actuator 70 Ex Ex II 2G Ex d IIC T6 (ATEX) The TA 70 Ex can be used for many purposes thanks to its wide range in terms of running speed and torque.   Examples of applications in hazardous areas : tankers, natural gas filling stations. Also mounted on unmanned drilling stations in the North […]


TA Actuator 70 All-purpose actuator which can be easily customised to specific demands.   Suitable for spindle and linear valves. Converts the smallest electrical impulses into rotary and linear movements. Maintenance free functionality lasting many years e.g. for 8 way ball taps in petrol additive facilities (“Ex” area). Advantages : High torque (up to 32 Nm) […]
