HIGH TEMP. VALVES
General
Habonim’s High Temp. product line valves are subject to the general Habonim valves
design, materials, practices, methodologies and certifications – for more information, see
Valves General chapter.
Habonim Control valves are equipped (in some series) with the Total HermetiX integrity
package for superior sealing, safety and environmental care.
High Temperature - Metal Seated Ball Valve
Habonim’s extended line of High Temperature - metal seated valves perform and excels in the
harshest industrial environments, where valve durability is critical to ensure safety, minimize
failures and promote efficiency. These meticulously engineered metal seated ball valves are
designed to withstand the harshest applications and process conditions, including extreme
high temperature, high pressure and abrasive medium.
Careful metallurgical selection of all valve parts, special surface treatments including hard
coatings, thorough analyses of mechanical strength and thermal expansion and vast experience
of successful installations ensure that Habonim High temperature – metal seated valve line is
the best choice for industry’s toughest applications.

Metal Selection and Surface Treatments
HVOF (High Velocity Oxygen Fuel):
Various HVOF spray solutions based on chromium and tungsten carbides. Is used for applications
up to 650°C (1200°F).
ASME B16.34 listed forged bar materials:
Even for the higher temperature range up to 650°C (1200°F) Habonim uses ASME B16.34 listed
forged bar material for the construction of the valve pressure-containing elements.
Stellite welding:
For severe abrasive conditions such as pulp and paper processing, Habonim uses a minimum
of 1.5 mm thick, hard stellite coating. These coatings are specifically engineered to meet the
customer’s application to provide outstanding resistance to abrasion and corrosion for a
lifetime of effective operation in harsh applications.
Lapping:
Each ball and seat sub-assembly is accurately machined, ground and then mate-lapped for a
perfect match. The complete valve assembly demonstrates high repeatability in terms of sealing
(Rate B - factory tested), low torque and smooth operation at various temperatures and pressures.
