Retractors are extendable cleaning nozzles. By using retractor nozzles, the highest level of safety and hygiene can be achieved. Our selection of retractor nozzles includes devices with spring or compressed air retraction. Nozzle extension in these devices is usually accomplished via fluid pressure. Retractors can be equipped with static spray balls, Chemidisc and Chemitorus series slide bearing nozzles, and high-speed rotating ball bearing nozzles. The position of a retractor nozzle (open/closed) can be checked by means of a magnetic sensor. Our retractors can be adapted to individual needs. Depending on the type of device, FDA conformity as well as EX exemption and stroke lenghts between 50 mm and 1000 mm are possible.

Function

During the cleaning process, the spray head is pneumatically controlled and extended. After the cleaning process, the spray head is returned to its rest position by the strong spring load from the product chamber.

The IS25 has a spray head which is extended for cleaning in containers or pipelines. After the cleaning process, the spray head returns to its rest position and closes flush with the product chamber.
The use of the IS25 considerably reduces cleaning costs, because there is no need for buildup in agitator vessels or flooding of pipelines.
The IS25 is particularly suitable for cleaning tanks with moving internals, such as beam agitators and scrapers.
With the IS25 it is now also possible to clean bulk material pipelines with a minimized quantity, previously only possible with the use of a large quantity of cleaning agent. This considerably reduces energy and investment costs, as the cleaning agent consumption of the IS25 is only approx. 3.4 – 4.8 m³/h at 2 bar.

Application Areas and Cleaning Diameters

IS25 Device Description

Splash-proof connection head to protect the electrical installation (up to IP67).
Very compact and reversible actuator – spring closing / air opening or vice versa. Air support of the spring chamber is possible.
ECOVENT® -E actuators have the possibility of internal airflow.
Due to the open lantern, a defective rod seal and the valve position can be recognized immediately.
Reliable sealing at the valve stem – highest surface quality due to rolled stem surface.
One or two-piece housing.
The metallic stop of the valve disc results in a defined deformation of the seal. This results in a long service life.
Seat ring and guide for the spray head.
Removable spray head
Easy installation and removal by means of a hinged ringSplash-proof connection head to protect the electrical installation (up to IP67).
