PEECO High Pressure Flow Switches
For Hazardous Locations with Maximum Allowable Pressure to 10,000 PSI
Utilizing
¼" thick Heat Treated aluminum cover with
5 fully engaged threads, all units are designed to encapsulate
any internal explosion. In lieu of a bellows assembly
a solid rod extends through a flexure tube brazed or
welded into a S.S. ball fixture. Unit has been successfully
field tested up to 10,000psi. Wall thickness of the
flexure tube will vary with pressure requirements. This
model is recommended for all pressures over 600psi.
Each of the four basic styles shown are adaptable to
many other fittings and configurations.
