CAST IRON GATE VALVE 30CH6BR
Closing and opening of the 30ch6br gate valve is performed manually. Due to the progressive movement of the stem when turning the handwheel, the wedge rests against the support wall, pushing the disks apart. As a result, the sealing surfaces of the disks are pressed against the sealing surfaces of the body, ensuring the closure of the passage.
