Limiting valve LPS/L25

Vacuum limiter (L)

Description

Low pressure relief valves control primary pressure (p1, ahead the valve). The low pressure relief valve (also back pressure relief valve) LPS is used in chemical and pharmaceutical industries for blanketing or inertization of reactors, storage tanks and vessels with inert gas such as nitrogen.

Technology

The spring loaded construction with large diaphragm provides an excellent control performance. A direct guided valve with large size enables fine regulation of back pressure as well as safe pressure relief at varying gas flow rate.

Application

This vacuum limiter LPS/L is used to protect vessels and storage tanks against implosion. With too low pressure, atmospheric air or ventilation gas can be drawn via the regulator.
