Product catalog summary
Overview: The document is a technical catalog from OLEOWEB detailing specifications and performance data for single counterbalance valves designed for open center hydraulic systems. It includes information on product modifications, technical data, and ordering codes.
Specifications: The catalog specifies various valve sizes with BSPP thread types ranging from 1/4 to 3/4 inches. Each size has a corresponding maximum flow rate and pressure capacity, with detailed dimensions provided for each valve type. The materials used include steel with zinc or zinc-nickel plating.
Performance Data: Performance graphs illustrate the relationship between flow rates (in l/min and USgpm) and pressure (in bar and PSI) for different valve configurations. The document specifies the pilot ratio options and standard spring settings for pressure adjustments.
Technical Data: The valves are compatible with mineral oil ISO 6743/4 (DIN 51524) and require oil viscosity between 15-250 mm2/s. The maximum contamination class is ISO 4406:1999 Class 19/17/14. Operating temperature ranges are specified for both oil (-20°C to +80°C) and environment (-20°C to +50°C).
Recommendations: It is advised to use a 15 μm filter to protect the valve from contamination. The document emphasizes the necessity of filtration to maintain valve performance and longevity.
