Outlet valve with a 60° outlet nozzle

Picture: DDPS

To allow an easy interchangeability and compatibility to its customers in pharmaceutical and fine chemical field, De Dietrich Process Systems (DDPS) has extended its range of disc bottom outlet valves by adding a 60° outlet nozzle version. As an alternative to the approved 45° valve, Cleanvalve with all its special properties is now available, with a 60° outlet nozzle according to DIN 28140-1. This DIN Norm defines the angle (60°) as well as the exact position of the outlet nozzle flange. This allows easy retrofitting on existing reactors and tanks made of glass-lined steel, stainless steel or nickel alloy. All features of Cleanvalve 45° are preserved with the following advantages:

  • Patented flat seat to avoid collection or build-up of materials in the annular area between the valve seat and nozzle wall
  • Self draining design of the internal components and body
  • Cleanvalve is able to accommodate temperature measurement sensors, measurement electrodes at the lowest point in the vessel
  • All DDPS glass-lined valves are made of cast steel coated with the standard DD3009 enamel identical to the reactors on which they are installed. Wetted parts feature the same characteristics of all other glass-lined equipment.
