FV25 / FV50 – FLUSHING VALVES

CHARACTERISTICS

Flushing valves – FV25 / FV50

APPLICATION

The new HOMA flushing valve prevents the building up of grease and solids in pump sumps. Every time the pump starts, the valve is opened and a part of the pumped liquid is blown through a jet nozzle into the sump, flushing all solids into suspension, so that they are pumped away within the pumping cycle.

CHARACTERISTICS

Flushing valves – FV25 / FV50

APPLICATION

The new HOMA flushing valve prevents the building up of grease and solids in pump sumps. Every time the pump starts, the valve is opened and a part of the pumped liquid is blown through a jet nozzle into the sump, flushing all solids into suspension, so that they are pumped away within the pumping cycle.

MATERIALS

Housing (Stainless steel 1.4436) Adjusting screw (Brass) Diaphragm/Jet nozzle (NBR) Ball seat (Stainless steel 1.4571) Ball (FV 25: Ball bearing steel FV 50: NBR with steel core) Oil (Food save)

CONSTRUCTION TYPE

The flushing valve is installed between the pump discharge fl ange and either the guide claw (if a coupling system is used) or the discharge pipe (if the pump is set up on the ground). Adapter kits DN 50 (2″) to DN 150 (6″”) are available for different discharge diameters. On larger pumps, the flushing valve can also be mounted directly on the cleanout. The valve is operated by using the venturi effect and pressure difference. It works without any additional energy input or control. The flushing time can be individually adjusted between 20 and 50 seconds. In addition, the design allows an easy replacement of wearing parts like nozzle or ball seat.”

FEATURES

The valve nozzle can be directed either at the bottom of the pit to prevent sedimentation or upwards to prevent the formation of a scum layer, especially on liquids with high grease content. At the end of the preset flushing time, the valve closes automatically to complete the flushing process. The dispersed pollutants are pumped out with the medium. After the pumping process, the fl ushing valve opens again automatically for the next flushing process.
