  • Low hysteresis for accurate pressure regulation and good stability.
  • High flow capacity relative to physical size.
  • High reverse flows from port 1 to port 2 may cause the main spool to close. (If reverse flow is required, use an external reverse flow check.)
  • Very flat pressure override vs. flow characteristics.
  • Low pilot flow out of port 3 (7 to 20 in3/min [0,11 to 0,33 L/min] depending on frame size). If pilot flow is critical, consider using direct acting versions.
  • Dynamic response is slower than with direct acting valves.
  • Recommended maximum inlet pressure is determined by the adjustment range. Ranges A, B, N, and Q are tested with a 3000 psi (210 bar) maximum differential between inlet and reduced pressure. Range W is tested with 5000 psi (350 bar) of inlet pressure.
