Precision Hydraulic Control with Sauer Manual Mechanical Servo Valve

Engineered for high-performance hydraulic systems, the Sauer 90R series delivers unmatched directional control with manual mechanical servo operation. Its hardened steel core components ensure extreme durability under continuous high-pressure conditions (up to 350 bar).

Ultra-responsive spool design guarantees millisecond-level adjustments, ideal for industrial machinery, mobile construction equipment, and precision agricultural hydraulics. The corrosion-resistant aluminum alloy housing features CNC-machined fluid channels for optimized flow efficiency.

Key advantages include zero internal leakage due to lapped valve seat surfaces, interchangeable 90R055/075/100 cartridges for flexible pressure ranges, and O-ring seals rated for -40°C to 120°C operation. Backed by Sauer"s aerospace-grade manufacturing standards.

Exclusive bulk pricing available for fleet operators and OEM procurement. Ships globally with certified pressure test reports.
