Features

  •  Installation Adaptability—360-degree
adjustability of the body/diaphragm case connection
and four-position vent mounting permit flexibility in
vent positioning and installation in awkward positions
or limited spaces. Units may be mounted in any
orientation without affecting proper operation.
  •  Tamper-Resistant Adjustment—Closing cap and
spring case on most types allow installation of sealing
wire to discourage or detect unauthorized adjustment
of the pressure setting (Figure 2).
  •  Rugged Construction—Diaphragm case and
internal parts are designed to withstand vibration
and shock.

  •  Precision Control of Low-Pressure Setting—
Large diaphragm areas provide more accurate
control at low-pressure settings.

  •  Corrosion Resistance—Constructions are
available in a variety of materials for compatibility
with corrosive process gases.
