easily adjusted via unique valve mechanism (patented) by varying the compressed air supply.
The ability to adjust the impact force will enhances the air knocker capability to work on unforeseen circumstances such as changes of material characteristic due to the process.
*The blue part is the unique “umbrella type valve”
Multiple Air Knockers operated in Cascade Connection
* RKVS15 type does not support the relay piping.In combination used with fully pneumatic operated controller (AOC-1B), the air knocker can be easily add on to the hopper, piping …etc. without electrical works! The AOC-1B controller can be actuated manually by a 3-way hand valve (In-built) or automatically by an external 3-way solenoid valve or pneumatic valve.
The electrical/pneumatic signal to actuate the solenoid/pneumatic valve could be from the down stream equipment such as rotary valve, slide gate valve, butterfly valve…etc.
The RKVS15 can be installed with a M10 bolt. Therefore, it can be installed on your idea such as installation with the dedicated stay bracket, with no knocker mounting stay provided on the container or with no soldering of container.
The repair kit consists of 4 replacement parts only and can be easily replaced within 10 minutes.
The stainless steel knocker series have durability supported by high design basis and have a simple structure, which provides almost maintenance-free performance and requires no additional spare parts. In long-term delivery record of this air stainless steel knocker series, customers have appreciated its maintenance-free performance with almost no failure
