Pressure Switches

The following components are available for monitoring the pipeline pressure.
Pressure switches. These are preset for normal line pressures (4 bar & vacuum only). They have a 1/4 BSP male thread and are supplied with a dowty seal. Maximum over pressure of 300bar allows pipeline testing without removing pressure switches from the line.
Manifolds. Manifolds are brass bodies with 15mm copper stubs and are available as single or twin units. Both types incorporate minimum leak devices which allow pressure switches to be changed without dropping pipeline pressure.

Pressure switches & manifolds are de-greased for use with oxygen & are supplied in sealed packing
