Linear Piston Pneumatic Actuator

Indicator

The NAMUR standard indicator facilitates the installation of position switches,

positioners and other accessories.

Output shaft

Nickel-plated alloy steel, high-precision one-piece output shaft also meets

NAMUR, ISO5211, DIN3337 standards. Sizes and stainless steel materials can

be customized according to customer requirements.

Cylinder

ASTM6005 die-cast aluminum alloy cylinder body can be hard-oxidized,

epoxy resin sprayed , PTFE coating or nickel plating to meet different

requirements.

Piston

The double-piston rack is made of cast aluminum hard anodized or steel

galvanized. The installation position is symmetrical, the action is fast, and the

service life is long. Simply invert the piston to change the direction of rotation.

Stroke adjustment

Two independent stroke adjustment screws can adjust the switch position

conveniently and accurately ±5°.

High performance spring

Using high-quality materials, coating treatment, pre-compression assembly.

It has strong corrosion resistance and service life. It can safely and simply

disassemble the single-acting actuator, and meet different torque output

ranges by changing the number of springs.

Bearing, guide plate

The use of low-friction, long-life composite materials avoids direct contact

between metal and metal, and is simple and convenient to maintain.

Seal

Use nitrile rubber under normal temperature working conditions, and use

fluorine rubber or silicone rubber at high or low temperatures.

GEKO Actuators (Pneumatic, Quarter turn or Linear - SIL 3 Certified)

For pneumatic actuators the sealing with flanges and piston is performed

by means of a floating O-ring design and guided internally by a sliding

ring in Teflon graphite.

For sealing with flanges and piston is performed by means of O-rings and

guided internally by a sliding ring in Teflon bronze.

All seals are specifically designed and chosen on the basis of the use cases:

ambient temperature, supply medium type, etc.
