Main Features

Options

"Floating Ball" design insures a positive, leak-free seal and
automatically compensates for any seat wear or misalignment.
Available in Carbon Steel and Stainless Steel.
1/4 turn positive operation.
Hard-chrome plated micro-smooth ball greatly
reduces friction and seat wear.
Ball seats are available in a variety of materials to
suit your special applications.
Depending on size and materials, working pressures
up to 800 bar / 12000 PSI and temperatures up to
+500 °C / +930 °F can be accommodated.
Full size ports on most two-way valves virtually
eliminates pressure drop.
STAUFF Ball Valves offer completely bidirectional
operation, eliminating any chance of incorrect installation.
No lubrication or maintenance required for the life of the valve.
STAUFF Valves are easily and completely repairable.
Long seal life.
No threads in fluid service to contaminate flow or cause
turbulence.

Contact STAUFF with your special requirements.

Please note:
STAUFF Ball Valves are designed for use as on/off devices
and must not be used to throttle fluid flow. Use in any
position other than fully open or fully closed can lead to
rapid deterioration of valve components and possible
product failure.

When operated from the fully closed position at rated
operating pressure, manual operation may prove difficult
due to opening torque requirements.
Please consult factory prior to field application.
