81521856065 MAN Servo Valve | Precision Hydraulic Control Unit
81521856065 MAN Servo Valve Pneumatic Control Module
Engineered for MAN commercial vehicles with air-assisted steering systems, the 81521856065 Servo Valve utilizes
low-friction spool design for pressure-sensitive modulation.
Features triple-seal protection against road contaminants in heavy-duty environments.
The temperature-compensated mechanism maintains consistent flow rates
across (-40°C to +120°C) operational range. Electropneumatic interface
ensures millisecond-level response during emergency maneuvers.
Engineering Parameters
• 45mm compact housing
• IP67 ingress rating
• 0.8-12 bar operating range
• 230g mass density
• 6mm fluid ports
• ECE R110 certified
• <2μs response lag
