SUPPLEMENTARY
LOADING SYSTEMS
Improve the operating characteristics of your safety valve
The LESER Supplementary Loading System (SLS) is an
accessory that can be installed on new safety valves or
on safety valves already in operation (retrofit). It serves to improve the operating characteristics of the safety valve.
​
The main applications for the SLS in the pulp and paper
industry are:
​
-
The protection of the drying cylinders
-
The protection of the steam boiler
Benefits of the Supplementary Loading System
The Supplementary Loading System supports the opening and closing of the safety valve. The LESER Supplementary Loading System improves the operating characteristics of safety valves in the following areas
-
Higher process productivity due to working pressure up to 97% of set pressure.
Less loss of media when the safety valve opens and closes. -
Shorter duration of noise emission
-
Fully tight up to the set pressure.
-
Less wear of the safety valve
In the new brochure, LESER describes in detail how it works and also in detail the components and necessary requirements for installing the Supplementary Loading System
