quarter turn vane type pneumatic actuator

タイトルまたは説明

Compact,lightweight,yet powerful.
EHO-QTV Vane actuators are smaller than other types of actuators in the torque output range of up tp ****0 in-lb.EHO-QTV Vane actuators produce a high ratio of torque output per pound of actuator weight.
Long life
Exhaustive factory tests and customer applications have substantiated the long life of EHO-QTV vane actuators.
Durable housing
The housing is die cast aluminum for maximum strength. The housing is then coated with a high quality alkyd enamel for excellent atmospheric corrosion resistance.

Modular construction
Accessory control components can be easily added in the field.

Ease of installation
EHO-QTV Vane actuator is easy to install because of their lightweight,compact design.Mounting kits are available for all types of valves and other devices.

Wide temperature range
EHO-QTV Vane actuator can operate efficiently from 0℃ to**0℃. Contact the factory for applications in other temperature ranges.

Simplicity
Only one moving part,the vane(paddle), is needed to transmit the torque to the valve.Because the paddle is cast directly on the shaft,there is no lost motion during the stroke. This design provides excellent repeatability when used with a positioner.

Uniform seal
The paddle comes assembled with integral nylon bearings to equalize O-ring compression around the paddle.

Low friction
The EHO-QTV Vane actuator use the excellent O-rings and bronze bushings to minimize friction. The result is a design which is more than *0% efficient in torque output.

Low maintenance
There are only 3 soft parts which can wear during operation*1 paddle O-ring and 2 shaft O-rings.These O-rings are easily replaced and are readily available from the factory and all automation centers.

External stroke adjustment
The EHO-QTV Vane actuator is designed with convenient external travel stops to allow a wide range of rotation adjustment(+/**0 at each end of the stroke).
