The gate valve can only be fully opened and closed, and cannot be adjusted or throttled. So rising gate valve is also one kind of gate valve. By turning the handwheel, the threads of the handwheel and the valve stem move forward or backward, and the valve plate connected to the valve stem moves up or down to realize the opening and closing function. In summary above, this is the rising gate valve we use.
