Chemical compatibility
The information presented in this bulletin is intended as a guide to the chemical resistance of materials used in Habonim valves. The physical properties of a material are affected differently by each corrosive media. An "A" rating is associated with internal moving parts that are in direct contact with the media. In some cases a "B" rating can be given to body material that comes into direct contact with media if the media’s corrosion rate does not pose a serious problem.
Flange dimensions
Flange dimensions are determined by the pipe size and the pressure class required for the application. Habonim Flanges are standardized according to ANSI B16.5 & DIN EN1092.
Maximum Allowable Stem Torque (MAST)
MAST is the Maximum Allowable Stem Torque to which a quarter-turn valve stem can be subjected during operation without mechanical failure.
Polymer characteristics
Habonim’s extensive field experience, which lets us design valves that meet the diverse needs of industry, also takes advantage of ongoing developments in polymer seat materials. This section describes Habonim’s line of engineered polymer materials, each with its own special characteristics that optimize it for specific industrial needs.
Data Sheet Valve Torques
The operating torque of the ball valve is influenced by a number of factors, some are design related and others are material related. The torque required to operate a ball valve is a function of friction between the valve’s metal parts and its soft sealing materials. The valves torque data sheet provides graphic information for most of the valves series for your convenience.
