Time proven magnetic head leak proof construction combines with a
heavy duty welded chamber to provide excellent reliability for control
of compatible liquids. Operating pressures of 1250 psig (86 bar) at
650°F (345°C) and 750 psig (52 bar) at 750°F (400°C) are standard. The
use of an external magnet reduces the possibility of magnetic particle
build up inside the armature tube and subsequent loss of operation as
may occur with the internal magnet repulsion design. The controls
feature carbon steel bodies and stainless steel internal trim. Process
mounting configurations include either side/bottom combination 1"
NPT/socket weld hubs, side/bottom flanges or side/side flanges. A
variety of hermetically sealed snap action or mercury switches are
available in SPST, SPDT, or DPDT action for single or two stage
operation. Mercury or Gold alloy snap action contacts are suitable for
low current DC applications. A full range of switch enclosures are
offered. Many chamber, enclosure and switch combinations are UL
approved.
