Sun Hydraulics PB*B Pilot Operated Reducing Cartridges - Three Port

Pilot-operated, pressure reducing valves are ideal for circuits with multiple pressure requirements to be operated with only a single pump because of the high primary pressure at the inlet port 2 to a constant reduced pressure at port 1.

Features:

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.
