KEY BENEFITS: 1106 PULSATION DAMPENER
• Adjustable, self cleaning
• Protects pressure instruments from process
pulsation
KEY BENEFITS: 1112 PRESSURE SNUBBER
• Filter disc available with wide porosity options
for a variety of process media
• Low profile design for space restricted
applications
1106 - Provides restriction by means of a moving pin, which may
be placed in either of five different sized holes, and this allows the
user to vary the amount of dampening to suit the requirements.
The pulsating pressure moves the pin up and down, providing
a self-cleaning action. Dampeners are shipped with a pin in the
‘middle’ hole, and may be used in either a vertical or horizontal
position. Maximum pressure is 5000 PSI.
1112 - Used for dampening and filtering, the snubber has a metal
disc available in four grades of porosity. The one best suited for
the application can be selected from the ordering code. Due to
the large filter area, the snubber has less tendency to clog than
orifice-type devices. All-metal construction permits the snubber
to be washed in a variety of common solvents.
