The document outlines the specifications for M22x1.5 single acting pilot check valves (VPR). The valves are designed with poppet sealing and are available with different spring options: 5 bar (72.5 PSI) and 8 bar (116 PSI).
Technical Data
Max flow rate is 50 l/min (13.3 USgpm) and max pressure is 350 bar (5075 PSI). The approximate weight is 0.14 kg (0.30 lb) and the tightening torque is between 44-50 Nm (32-37 lb ft). The pilot ratio is 1:2.5 and the cavity type is C2215/3.
Performance
The document includes performance graphs showing flow rates and pressure in bar, PSI, USgpm, and l/min.
Technical Characteristics
The valves use mineral oil ISO 6743/4 (DIN 51524) with a viscosity range of 15-250 mm2/s (15 to 250 cSt). The maximum contamination class is ISO 4406:1999 Class 19/17/14. Oil temperature ranges from -20°C to +80°C (-4°F to +176°F) and environment temperature from -20°C to +50°C (-4°F to +122°F). A filter with 15 μm filtration is recommended to protect the valve.
Ordering Information
The document provides an ordering code for the valves, indicating the type, size, sealing, and spring specifications.
