AFO Compact Cylinders



Clippard Air Force One® Compact Cylinders


Clippard Instrument Laboratory’s Air Force On

e compact cylinders are available in double acting, spring return, spring extend and double rod models. GMR sensors and magnetic piston versions are also available.

The AFO cylinder features include a stainless steel tube and roller burnished piston rod. This means longer rod and piston seal life. For corrosive environments, where dirt and abrasives may be ingested, and cause seals to wear faster than normally expected, the AFO offers the benefit of tie rod construction. This enables seals to be replaced, rather than replacing the entire cylinder. The non-corrosive construction of the AFO cylinder body is reliable in abrasive environments, able to withstand the toughest conditions.

The various mounting configurations available in the AFO cylinders assure freedom to interchange with most cylinders on the market. This means most systems can be upgraded to include quality AFO cylinders.
Magnetic Pistons & GMR Sensors
Position Sensing Switch

Clippard offers the solid state circuitry of the GMR Switch to reliably detect the presence of a magnet attached to the piston. Clippard’s GMR Switch incorporates an LED to visually show switch actuation. The GMR Switch is offered in sinking (NPN) and sourcing (PNP) and with a variety of cable configurations.




Locating GMR Sensors on Cylinders


Cylinders ordered with magnetic pistons come with an additional attached rod* on which the GMR Switch can be attached. The Switch snaps onto the rod and can be slid into the desired location. A set screw is used to lock the GMR Switch in place.

* Additional rod is not used on 1 1/2″ Bore Cyl. GMR Switch can mount directly to any tie rod.
Magnetic Pistons

A specialized magnet is attached to the piston that will actuate the Clippard GMR sensors. This allows one or more of these dependable electronic sensor/switches to accurately determine the position of the cylinder rod. To order cylinders with magnetic pistons, specify model numbers that end with -M. GMR sensors must be ordered separately.
Brass Cylinders

ES Series Valves




Clippard ES Series Valves

The compact ES valve, like Clippard EV and ET valves, converts low voltage, low current signals into high pressure (0 to 105 psig) pneumatic outputs, utilizing a unique, patented valving principle. Since there are no sliding parts, and complete poppet travel is only 0.007”, low power consumption and exceptionally long life are assured with this design. No flow is required for cooling because the compact ES is cool, as well as quiet, in operation.

The compact nature of design makes this valve well suited to a wide range of applications in biomedical, environmental test equipment, textile machines, packaging machinery, computerized industrial automation, and portable systems.

• Close mounting – 7/8” on center
• Overall height less than 1”
• Easy to mount on manifold with two #4-40 screws
• Geometric design
• Polymer housing – Zytel ST 801® super tough
• TE Connectivity-style pin connection or 18” wire leads
• Flow up to 0.6 scfm (17 l/min)

As in the case of the EV/EVO product, the ES/ESO uses the single moving part design proven many times in the EV/ET/EC series valves. Of course, given the reduced size of the coil the power to operate increases to 1 watt.

Because of its reliability, the ES/ESO series valve is found in many of the same applications and industries as its predecessor, the EV/ET/EC. However, the smaller size finds it used more commonly in portable or mobile equipment. This makes the valve particularly applicable in home healthcare applications.

Valves are small in size with a variety of coil voltages and flow options. Mounting is as close as 7/8” on center.Housing is molded Zytel® ST 801 for toughness and rigidity.
Valves feature low power, cool running, quiet operation and fast response time. They convert low voltage, low current signals into high pressure pneumatic outputs.
ESO and similar styles have top hose barb or #10-32 threaded fitting for N.C. exhaust or N.O. inlet.
Coils are available to mate with TE Connectivity
#5-103956-2 with connector or with 18” wire leads which utilize #26 wire.
Clippard ES valves are unique, with only one internal moving part that travels a mere 0.007”
EFB Fill & Bleed Circuits

Clippard’s EFB series electronic fill and bleed circuits are a combination of Clippard pneumatic valve components used to inflate a volume or apparatus in one controllable function, and to release or vent pressure in a second controllable function. Fill and bleed circuits are commonly used in many applications where a particular pressure, firmness, or position can be controlled with the addition or venting of pressure.

• Compact, robust design
• Extremely fast response
• Exceptionally long life

Intrinsically Safe Valves

Clippard Intrinsically Safe Solenoid Valves
The design of Clippard electronic valves is a deceptively simple arrangement with a minimum of operating parts, and remarkably straight forward low power operation. The “spider” is the only moving part and its motion to operate the valve is a mere 0.007″ travel. Low voltage DC inputs, signals from simple manual switching up to computer directed systems, move the spider in extremely fast response time… 5 to 10 milliseconds. The unit uses extremely low power (0.67 watts at the rated voltage) and is cool running. The valves are lightweight, compact in physical size and mount easily in space-saving packages. The Intrinsically Safe Series Solenoid Valves are available in 2- and 3-way configurations and feature low power consumption. In-line or manifold mount available. Normally-Closed or fully-ported. Multiple connection options.

What is Intrinsic Safety?

An intrinsically safe system is one in which all electrical devices and their associated circuits are designed such that they can neither arc nor spark with sufficient energy to ignite the hazardous substances around which they are being used. Put another way, the energy stored from the inductance of the circuit components must be unable to generate a spark or arc at the circuits open point during current circulation that is capable of igniting the hazardous materials present when they are in a fuel/air mixture that is most favorable for ignition.




What is Entity Approval?

According to Intrinstic Safety standards, there is no requirement for authorized laboratory certification of system-wide Intrinsic Safety if the designer can determine, with certainty, that the physical and electrical parameters of every system component has been met sufficient to ensure that system-wide intrinsic safety has been maintained.

An “Entity Approval” is documentation stating that a device is Intrinsically Safe in specified hazardous atmospheres if the stated physical and electrical conditions contained in the approval are met. By meeting the requirements of “Entity Approvals” on all components of a system, the designer can more easily document that system-wide intrinsic safety has been maintained.

The Clippard EI-EIO Series valves hold the Entity Approvals listed and supporting documentation is available to our customers.

EGV Poppet Valves

EM Series Valves

An even smaller Mouse valve! When space is critical, the EM Series Valve provides the best solution. At just over an inch tall, and less than 3/4” in diameter, the EM Valve uses Clippard’s special “spider” design. This reliable and proven design for long life is housed in a miniature body, and incorporates wire leads out the top, allowing body rotation for close-center mounting. In addition, the valve

features higher flow; combining fast shifting speed, extremely high cycle life with the design flexibility to make this valve a “small wonder” for demanding applications.

Control Data

A Bipolar Chopper Drive (not included) is a power-efficient method of using current to drive a stepping motor to obtain high stepping rates. The chopper gets its name from the technique of rapidly turning the output voltage on and off (chopping) to control motor current.

Stepper motors require some external electrical components in order to operate. These components typically include a power supply, logic sequencer switching components and a clock pulse source to determine the step rate. Many commercially available drives have integrated these components into a complete package.
