Rack and pinion actuators

Their high quality is consistently confirmed by independent testing series performed by the large-scale chemical industry, both nationally and internationally. The design principle of the rod-guided pistons is based on a patented system that delivers crucial benefits: our drives are maintenance-free, compact and offer high levels of reliability and long service life.

More info...

Wherever liquids, gases or vapours are conducted through pipelines there are valves and fittings, which must be actuated or moved.

Rack and pinion actuators are essential components of an actuator system consisting of valves and fittings, directional control valves or positioners and end position monitors. These units are inter-connected via standardised interfaces. From the process control system, from programmable controls or from other control devices, positioning signals are transmitted to the rack and pinion actuators via directional control valves or positioners. The rack and pinion actuators then mechanically translate the signals into rotary motion, which actuates the valves and fittings.

Thanks to their compact design and high performance our rack and pinion actuators are preferably used for automation of ball valves, plug valves, butterfly valves and control valves.

Position monitoring units

Position monitoring units enable reliable monitoring of end and intermediate positions of drives. In addition, running times can be monitored in case of special safety requirements.

More info...

Position monitoring units enable reliable monitoring of end and intermediate positions of drives. In addition, running times can be monitored in case of special safety requirements. Positions are monitored by initiators （slot form or cylinder form） or by limit valves and micro-switches with or without protective casings （design according to VDI/VDE 3845）. We offer versions with various protection class conformances, e.g. IP65, IP 68, Ex2, ATEX, NEMA or GOST.

Positioners

Positioners are used in the process industry for controlling chemical and physical processes. Positioners fitted to pneumatic control valves are used to assign the valve position and position signal.

Positioners are used inthe process industry for controlling chemical and physical processes.Positioners fitted to pneumatic control valves are used to assign thevalve position and position signal. Depending on the respectiverequirement （e.g explosion protection）, pneumatic orelectro-pneumatic versions are used. Both analogue （4 ??" 20mAsignal） and digital （bus-capable） activation is available. Allinterfaces are NAMUR-conformant.

The digital positionerswe use have extended functionalities, such as autostart withself-calibration and self-diagnosis, and enable convenient on-siteoperation using local push-buttons and LEDs. Installation isperformed either directly or in accordance with IEC 534 Part 6（NAMUR）. Additional features: protection class IP 65 and NEMA 4X,explosion protection: EEx ia IIC T4 acc. to CENELEC or “IntrinsicSafety” acc. to FM and CSA.

Directional control valves

In fluid technology, directional control valves are used to open or block the passage for service media like compressed air or hydraulic fluid or to change the flow direction. The valves are actuated electrically, pneumatically, mechanically or manually.

In fluid technology,directional control valves are used to open or block the passage forservice media like compressed air or hydraulic fluid or to change theflow direction.

The valves are actuatedelectrically, pneumatically, mechanically or manually. Our productrange includes 5/2-way and 3/2-way valves with ¼ inchconnections or special sizes, which can be flanged directly to theassembly according to VDI/VDE 3845. For high safety requirements,redundant versions are available.

Electro-magneticallyactuated and directly controlled poppet valves are suitable for awide range of service media: filtered, oil-free and dried compressedair, instrument air, nitrogen and other non-combustible, neutral, dryfluids （for versions suitable for liquid and aggressive fluids,please enquire）.

Poppet valves made byNORGEN have TÜV approval certificates based on IEC 61508 and DINV19251 and can be used in safety-relevant systems up to SIL4 and AK7*as well as in the applicability ranges of explosion protection typesEEx me. EEX md, XP （Div 1） in zones 1, 2 （gases）, 21, 22, dusts） ATEXCat. II 2GD.

The valves are mainlyused for control of single- and double-acting pneumatic processdrives.

Couplings/Brackets

Couplings and brackets are used to connect rack and pinion actuators and valves and fittings with each other. Our standard couplings are compley made of high-grade stainless steel. Our standard consoles are galvanised.For high-temperature applications, （hot vapour, superheated steam） higher-end versions in stainless steel as well as adapters with cooling fins are used.
