Product catalog summary
Overview: The document provides technical specifications and guidelines for OLEOWEB's unidirectional check housing valves (VUR-BSPP). It highlights the company's right to modify product details without prior notice.
Specifications: The valves are available in various sizes, from BSPP 1/8 to BSPP 2, with maximum flow rates ranging from 5 l/min to 430 l/min and maximum pressures from 400 bar to 250 bar. The approximate weights vary from 0.05 kg to 2.7 kg.
Sealing and Spring Options: The document specifies ball sealing for certain models (VUR180/140/380/120) with a standard spring pressure of 0.5 bar. Other spring options include 3 bar, 4.5 bar, 6 bar, and 10 bar (only for version 120).
Performance: Performance graphs illustrate the relationship between flow rates and pressure for different valve models, indicating their operational efficiency.
Technical Data: The valves are designed for use with mineral oil (ISO 6743/4) with a viscosity range of 15-250 mm2/s. The maximum contamination class is ISO 4406:1999 Class 19/17/14. Operating temperatures range from -20°C to +80°C for oil and -20°C to +50°C for the environment.
Recommendations: It is essential to use a filter with a recommended filtration of 15 μm to protect the valve. The maximum allowable leakage is 0.25 cm3/min or 5 drops/min.
