Habonim Metal Seated Ball Valve
Habonim’s tough line of metal seated valves excels in the harshest industrial environments, where valve failures can damage plant efficiency, reduce profitability and endanger safety. The meticulously engineered metal seated valve can withstand the harshest applications and process conditions, including extreme high temperature, high pressure and abrasive medium.
The lower temperature range from -60°C (-76°F) to 400°C (752°F) undergoes Habonim’s unique surface treatment, LTPN (Low Temperature Plasma carbo-Nitriding). LTPN is a cost effective hardening system for austenitic stainless steel, which provides a minimum thickness of 40 microns and more than triple (>68HRC) the natural hardness of the base material. For the higher temperature range from 400°C (752°F) and up to 538°C (1000°F) Habonim offers various HVOF spray solutions based on chromium and tungsten carbides.
For the even higher temperature range from 538°C (1000°F) and up to 650°C (1200°F) Habonim uses ASME B16.34 listed forged bar material for the construction of the valve pressure-containing elements.
For the severe abrasive conditions of the pulp and paper industry, Habonim offers also a minimum of 1.5 mm thick, hard stellite coating. Each coating is specifically engineered to the customer’s application in order to provide outstanding resistance to abrasion and corrosion for a lifetime of effective operation in harsh applications.
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. Habonim uses ASME B16.34 listed cast material for the valve body and ends.
