Technical specifications
* Easy construction
* Especially soft switching behaviour as the ST-261
* Easily operated adjustment and shifting
* Adjustable minimum and maximum pressure
* Extremely long durability

The unloader ST-291 is equipped with a thread for fixing it at the frame of your high pressure cleaner. According to in-house statements the switch with protection class IP 67 which is used for this valve is "as water-proof
as a submarine". Unlike to other valves the switch does not come into contact with water or other mediums as it is mounted on the outside of the valve and mechanically operated by the piston rod. It is of the directional contact type
i.e. that a contact is produced in any position.
