Fluid Power – Stainless Steel Pneumatic Actuator

Fluid Power – Stainless Steel Pneumatic Actuator


Series SSPA-10 (Stainless Steel Pneumatic Actuator Body Design)

The stainless steel pneumatic actuator series is a great solution for you heavy duty automation needs.  With a durable stainless steel body and manufactured to NAMUR standards and the option to add a solenoid valve, this actuator will continue to preform under time and pressure.  Each pneumatic actuator comes with a complete spring pack (which contains 6 springs per pack).  The benefits of using a stainless steel actuator is a corrosion resistance surface – resistance to most corrosive materials.  There is no lubrication needed for this series of actuators with a very simple maintenance and configuration cycle.



  1. Establish the valve manufacturer’s breakaway or seating/unseating torque, then add 20% as a safety factor.
  2. Determine available air pressure to the actuator (e.g. 60 P.S.I.).
  3. Refer to the chart, find the 60 P.S.I. column and scan down until a torque value greater than the valve torque is found (e.g. 141 in. lbs.).  Valtorc double acting actuator has no torque drop through the full 90º stroke.


  1. Establish the valve manufacturer’s seating torque (closing) and breakaway torque (opening). Add a 20% safety factor.
  2. Refer to the spring torque column and select the SPRING END TORQUE that equals or exceeds the required valve torque.
  3. Determine the available air line pressure to the actuator (e.g. 80 P.S.I.). Refer to the 80 P.S.I. column and scan down to where it intersects with the spring. In this case, the end spring torque is 112 in. lbs,. which exceeds the required 96 in. lbs. required.

Fluid Power – Ceramic Air Motors Put A New Spin On MRI Imaging!

When surgeons need to see inside a patient during a surgery, they often have to send the patient outside the operating room because the metal in a MRI system can interfere with critical equipment needed for surgery. Tasked with this challenge, the designers at Deprag Schulz GmbH & Co., Amberg, Germany, custom-designed an air motor to power the shield in open MRI machines. The result: a modular design that uses only ceramics and plastics, runs on oil-free compressed air, and is almost noiseless.

Open-MRI machines, like the one pictured, can use customized, metal-free air motors to allow them to be used in operating rooms without disrupting critical surgical equipment.

Using an MRI (magnetic resonance imaging) machine in an operating room would be ideal for clinical monitoring of minimally invasive procedures (keyhole surgery), during tumor operations on the brain or liver, and procedures involving the heart. However, ferrous metal in traditional motors that drive the MRI’s rotating shield causes interference fields in the operating room. The patient, therefore, has to be moved to an adjacent room accompanied by an anesthetist in the middle of an operation to be examined using operative magnetic resonance imaging. Such brain tumor examination procedures have been successfully carried out at the Neuro-surgical University Clinic in Heidelberg, Germany, for 13 years.

In an effort to reduce the need to move patients, research has been conducted to provide an accompanying MRI exam inside operating rooms. Instead of the usual MRI tunnel system, new open MRI exam systems enable doctors to access the target area of the patient during image scanning. The need then, was to develop a rotating MRI-imaging shield driven by a completely metal free-system, including the motor.

Going metal-free

A custom designed air motor from Deprag uses ceramic and engineered plastics instead of metal, thereby preventing it from producing stray electromagnetic fields.

Because they must contain metals to generate magnetic fields to convert electrical power into mechanical rotational power, any electric motor was ruled out. Therefore, an air motor became the most likely solution. The challenge to develop a completely non-metal air vane motor was presented to the Development Department at Deprag Schulz GmbH & Co., Amberg, Germany. Gerd Zinn , the head of Serial Machine Development remembers: “This motor was needed for diagnostics in an MRI system where the use of metal would cause interference with the operating system. Therefore, it was not a suitable material for the application.”

Product Manager Dagmar Hierl added, “Our ferrite-free air motors were designed and developed especially for such an application. These Deprag air motors can play an important role in the development of medical equipment.” This motor is suitable for other applications where the use of metal is out of the question.

Modular designs make for easy customization

Deprag specializes in air motors. Hierl said that 85 % of all the company’s projects are special solutions. “We individually adapt the air motors from our catalog to fit our clients’ specific requests. We are able to develop cost-effective special motors because of our modular system,” Hierl said. “The spectrum ranges from single air motors to fully automatic production systems. Creativity and customer focus are therefore very important to us.”

The team set to work, drawing on their knowledge from decades of developmental projects involving air motors. The result: an air motor made of ceramic and synthetic materials that does not contain a single piece of metal.

Circuits and systems made easy
Fluid Power Systems and Circuits, by Russell W. Henke, P.E., highlights circuit analysis and design flow for: constant and demand flow circuits, directional controls, pressure controls, and more. Complete with illustrations and easy-to-understand text, this book shows you how to analyze interactions of system components and how to pull an entire design together to meet anticipated loads and operating requirements. 400 pages, hard cover book, $80.00. Visit to order.

The prototype of the ceramic motor has a diameter of 40 mm and is only 78 mm long. Operating from compressed air at 2 bar, the motor transmits 150 W of power at a speed of 14,000 rpm. At its idle speed of 9000 rpm, it achieves 36 W power.

Because the entire motor system had to be metal-free, the pneumatic hose end fittings are also made of an engineered plastic. Three ports on the motor produce clockwise rotation, counter-clockwise rotation, and exhaust. In addition, valve circuitry is designed based on needs. For example, if one directional hookup is used (either CW or CCW only), a 2-position, 3-port valve is used. If bidirectional rotation is needed, a 3-position, 4-port valve will be used.

Zinn says the motor runs on oil-free compressed air. And although the research team did not require it, Deprag designers worked to reduce noise as well. To reduce noise from the motor assembly, a hose system was designed consisting of a combined inlet and exhaust hose.
