Key specs and benefits:
- Rated flow: 40 L/min (10.5 US gpm) for common mobile auxiliary functions
- Max pressure: 1 MPa (145 psi) for low-pressure hydraulic applications
- Fluid viscosity range: 12–400 cSt for broad oil compatibility across seasons
- Ambient temperature range: -40°C to +80°C for harsh outdoor environments
Typical applications:
- Material handling and industrial vehicles (e.g., forklift/stacker auxiliary control)
- Agriculture equipment (e.g., tractor attachments)
- Compact construction machinery auxiliary circuits
Supply capabilities:
- Manufacturer direct: wholesale, OEM/ODM, private label, and customization support for global distributors, agents, and traders.
