Spray Rinse Valve

Fetterolf rotating Spray Rinse Valves (also referred to as wash down valves) are designed to effectively rinse any size tank, vessel or reactor without the need to open them. This increases production time but more importantly assures employee safety by eliminating the requirement for personnel to enter a vessel or confined space that potentially has hazardous or toxic material.

Spray Rinse Valve

The Fetterolf rotating Ram-Seal spray rinse valve is used to clean the vessel walls of loosely attached coatings and solids to prevent build up and batch to batch contamination. This is extremely important in services that contain harmful substances that are life threatening such as VCM.

The rotating or linear washdown valve (spray rinse valve) is mounted to the top of the vessel. The number and size of valves are determined by the process, size and shape of the vessel. The valve eliminates the need for vessel opening or closing.


Spray Rinse Pattern

The Fetterolf spray rinse valve has been designed to allow cleaning of a vessel or reactor without entering the vessel or reactor. It is the result of many years of research and optimisation in live customer applications. Its most common application

Spray rinse valve during testing

is in the PVC industry. It is also used in styrene reactors and other polymer and paint applications. A high degree of customisation of the spray tube is available to ensure optimal rinsing for reactors that may have diverse pieces of equipment in the reactor (UV tubes in the CPVC process for example).

One key advantage of the Ram-Seal spray rinse valve design is that no chlorine, other gases or sediments can enter the valve in the open or closed position. This ensures free flowand no clogging, and means that the valve is always available to clean. It also ensures that any toxic gases in the reactor stay in the reactor.
