Butterfly valves

LTR43 - Triple offset butterfly valve


The Leusch LTR 43 triple offset butterfly valve is designed for general service applications up to the limits of the ANSI 2500 pressure class rating. These general service applications include process events such as erosion, abrasion, corrosion, cavitation, and flashing. The Leusch LTR 43 design increases flow capacity with the reduced pressure recovery factor compensated by special optional design features that address cavitation, flashing, and noise generation. The triple eccentric design of this butterfly valve will reduce the breakaway torques required from the actuator to nothing.

The Leusch LTR 43 control butterfly valve has standard options such as low and high temperature versions, heating jacket, NACE materials, etc. The Leusch LTR 43 can be assembled with a pneumatic, electric, hydraulic, or electro-hydraulic actuator also offered by the SAMSON group to complete the construction of the control valve. These control valves are designed according to the modular assembly principle.
