Series 57, 85

Product catalog summary

Overview: The document provides technical specifications and descriptions for low leakage cartridge couplings designed for machine tools, specifically Series 57 and 85 by WALTHER CONNECTING & DOCKING. These couplings are engineered to meet the demands of machine tools with features that include low leakage valve technology and versatile installation options.

Series 57 Specifications:

Materials: Stainless steel (1.4104 V) with chemical-resistant FKM seals.
Maximum working pressure: 200 bar (2900 psi).
Suitable for cooling lubricant, hydraulic clamping, and blow-off air.
Designed for depressurized connection.
Mechanically robust with protected seals.
Center deviation tolerance: ± 0.5 mm.

Series 85 Specifications:

Materials: High-quality steel, oil-burnished, with robust FKM/PUR seals.
Maximum clamping pressure: 240 bar (3480 psi).
Suitable for all common hydraulic oils.
Ultra-short coupling stroke “N”.
Encapsulated seals prevent dirt ingress.
Easy connection against residual pressures up to 40 bar (coupling to adaptor) and 60 bar (adaptor to coupling).
Center deviation tolerance: ± 0.3 mm.
Angular misalignment tolerance: ± 0.15°.

Performance Diagram: The document includes a performance diagram showing flow rates (Cv) tested according to DIN IEC 534 with water at 20°C, highlighting pressure differences for various models.

Additional Information: The document mentions that more coupling elements are available for special requirements from the WALTHER program. It also provides contact information for WALTHER-PRÄZISION.
