Product Advantages

- Full‑range pressure compensation to hold flow constant despite pressure changes.

Application Scenarios

- Flow is set by rotating the valve spool to vary the orifice area; the setting is independent of other port pressures.

- Available in two versions: with or without an adjustable spring safety (relief) valve.

- Product value

- Provides stable, predictable flow for hydraulic circuits, improving control accuracy and system performance.

- The optional built‑in safety valve adds protection against overpressure and simplifies system design.

- Suitable for integration into diverse hydraulic systems where consistent flow control is required.

- Product advantages

- Pressure‑compensated design ensures flow stability across a wide pressure range.

- Simple, mechanical spool adjustment for precise flow setting.

- Backed by ChangJia’s emphasis on design, quality control, technical capability, and customer service.

- Application scenarios

- Use in hydraulic systems for industrial machinery and manufacturing equipment.

- Mobile and construction hydraulics where stable flow is needed under varying loads.

- General fluid power systems, test benches, and any application requiring reliable, pressure‑independent flow control; ChangJia also offers tailored solutions based on customer needs.
