Accessories for gate valves
Product information
All Lohse knife gate valves can be individually adjusted. This allows the valves to be used in the most demanding business processes. A standard Lohse valve can be adapted to your specific wishes and circumstances by means of a modification or an addition.
Each Lohse valve can be easily modified through a number of applications or modifications.
The conical insert ring
The conical ring reduces the inlet of the valve in relation to the outlet. This directs the medium to the centre of the bore and prevents solid particles from remaining in the dead spaces of the valve.
The ring protects the pressed collars of the valve which, as long as the ring is mounted, are completely free of wear. The conical ring can easily be clamped between the flange and the valve. No modification of the valve is required.
A spring-loaded conical insert ring with scraper ring
The spring-loaded conical insert with scraper ring reduces the inlet of the valve relative to the outlet. This directs the medium to the centre of the bore and prevents solid particles from remaining in the dead spaces of the valve.
In addition, an integrated scraper ring scrapes the plate clean before entering the valve during operation. This prevents the medium from sticking to the valve plate and being pressed into the slide cups, thus preventing wear of the seals.
The conical ring can easily be clamped between the flange and the valve. No modification of the valve is required.
A conical insert ring with storm ribs
The conical ring with storm ribs reduces the inlet of the valve in relation to the outlet. This directs the medium to the centre of the bore and prevents solid particles from remaining in the dead spaces of the valve.
In addition, the ring is fitted with ribs that break up any vortices in the medium. This solution is mainly used for valves under cyclones or that have to deal with heavy vortices in the medium. Since the vortices are partially broken down, it significantly reduces wear on the plate, the pressed collars and the internal parts.
The conical ring can easily be clamped between the flange and the valve. No modification of the valve is required.
Special materials
The material of practically all parts can be adjusted as desired. The valve plate and the pressed collars can be made of hardened material, ceramic or special alloys. This will delay or even prevent wear. Ask our specialists for advice tailored to your needs.
Flush connections
All Lohse knife gate valves can be supplied with single or multiple flush connections. Flush connections can flush the dead spaces with air or liquid before the valve opens and/or closes. This prevents abrasive media such as salt, lime and sugar from solidifying, thus preventing the valve from jamming.
