Hand wheels, handles and Wei mechanism does not allow for lifting with. The flow of media should be consistent with the direction of the arrow body. Threaded valve, also known as the cross-sectional doors, is the most widely used of a valve, the reason it's popular is due to the process of opening and closing between the sealing surface friction is small, more durable, opening height is not easy to manufacture, easy maintenance, not only for low pressure, and is suitable for high pressure. Its closure principle is to rely on the valve bar pressure, so the valve seat sealing surface sealing surface snug fit to prevent the media circulation. Threaded media only allowed one-way flow valve, directional installation. Its structure is greater than the length of the valve, and fluid resistance, long-term operation, the sealing reliability is not strong.
