Overview of Primary Product
Adjustment knob
The shape of the knob is designed to ensure maximum comfort for
the operator and an accurate adjustment. 6 full turns of rotation with
10 decimal graduations per rotation allows for precise valve adjust-
ment. Shades of the scale indicator are large and clear allowing for
easy, accurate reading. The knob is made of a reinforced high strength
corrosion-resistant polymer.
Adjustment reference scale
Each 360° rotation of the knob moves the turn indicator by one
position, ranging from 0 (valve closed) to 6 (valve fully open). A
geared drive (6) allows for decimal graduations of the scale situated
around the knob itself letting the flow rate to be finely tuned.
Stainless steel valve plug (1)
High resistance to corrosion and erosion due to continual water flow or
impurities in fluid.
Teon stem guide bearing (2)
Prevents noise and vibration - particularly in severe operating
conditions.

Double internal o-rings
Double O-rings (3) prevent water from coming in contact with the screw
thread (4), which allows the rod (5) to fine-tune the calibrated valve plug
position (1). In addition, the resulting dry control stem thread prevents
seizing from scale after long in-operation periods.

Memory stop
The 130 series balancing valve features a memory stop that allows the
valve to be reopened to the initial position if it has been closed for any
reason such as isolating components in the balanced circuit. Locking
the position to be memorized requires the use of a 2.5 mm hex key.
Insulation shells
The 130 series balancing valve can be supplied with optional insulation
shells, code CBN130xxxx series purchased separately, to minimize
heat loss or eliminate condensation in chilled water applications.
