Gate valve for catalyst flow regulation has axial longitudinal sector of plate-side guide rods arranged so that they cover tube-side guide rods in one open position of valve

摘要

The gate valve has a tube sector (10) and a membrane (11) with aperture (12) and a valve plate (13) acting with the aperture. The axial longitudinal sector of the plate side guide rods is arranged so that the plate-side guide rods largely cover the tube-side guide rods (14) when the valve plate is in its second open position.
