Low pressure relief valve LPS/N25, SST

Reduzierventil LPR25

Negative pressure relief valve (N)

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

The back pressure relief valve LPS/N works under vacuum conditions with back pressure (p2) slightly below atmospheric pressure. Pressure ranges vary between -220 mbar relative and +5 mbar relative. LPS/N is a perfect pressure reducer for inertization applications under vacuum conditions.
