GKSL series pneumatic and hydraulic actuators provide global customers the latest valve actuation design. It is linear type.
Pneumatic cylinders (supply medium can be air or gas) are suitable for supply pressures up to 160 bar.Hydraulic cylinders are suitable for supply pressures up to 400 bar.
The mechanism of piston and yoke has an advantageous torque output.
The springs are fully encapsulated in a welded container, which encloses the spring assembly in a safety frame
arrangement that does not allow it to extend beyond a given value and ensures personnel safety.
The NAMUR standard indicator facilitates the installation of position switches, positioners and other accessories.
2. 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.
ASTM6005 die-cast aluminum alloy cylinder body can be hard-oxidized, epoxy resin sprayed (blue, orange, yellow, etc. sprayed as required), PTFE coating or nickel plating to meet different requirements.
4. End cap
The surface of die-cast aluminum alloy is sprayed with various colors of metal powder, PTFE coating or nickel plating treatment.
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.
6. Stroke adjustment
Two independent stroke adjustment screws can adjust the switch position conveniently and accurately ±5°.
7. 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.
8. 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 and replace.
Use nitrile rubber under normal temperature working conditions, and use fluorine rubber or silicone rubber at high or low temperatures.
GEKO Actuators (Hydraulic & 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 hydraulic actuators the 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.
