END-Armaturen ED620556

The ED/EE series pneumatic actuator is a high-quality device, developed and manufactured by us. The use of high-quality materials while considering high-quality demands is a guarantee for high operating reliability. The housing of this actuator is equipped with a PTFE-coating, similar to that of frypans. Due to its anti-adhesive effect, this makes it possible to prevent dirt from sticking or to remove it more easily. Advantages:

• Short-term availability of special types, development, manufacturing, assembly and quality control are completely „Made in Germany“
• Compact design without edges susceptible to pollution
• High-quality coating available from stock
• High pneumatic torque
• Stem and standard parts made of stainless steel
• Anti-blowout stem
• No change of dimensions for actuators with spring-return
• Price-performance ratio
• Simple, standardized mounting, extension or connection of signal transmitters or controlling devices according to EN 12116 (ISO5211)
• Power transmission via precisely performed involute gearing
• All plastic parts with a weight of more than 20 g are marked according to our environment management system DIN EN ISO 14001.

Function Description The actuator is a pneumatic twin-piston drive, designed primarily for operating ball valves and butterfly valves. A double-action and a spring-return (single-action) type are available. The twin-pistons provides high torque in a compact system. The rotation angle is adjustable by ±6° from the standard setting. Design Due to the twin-piston system the force developed by the counter-running pistons is transmitted to one common pinion via two tooth racks solidly connected with the pistons. This principle ensures a linear torque transmission along the entire stroke. In our shop, further versions of the pneumatic actuator ED / EE and an extensive range of accessories can be ordered online:

• Actuator with lower or higher torque.
• Actuator with ATEX approval for using in explosive atmospheres.
• Actuator with special surface coatings of the body, example: black anodized, hard-coated, chemical nickel plated and with PTFE-coating.
