Applications
Custom Agricultural Machinery: Specialized harvest headers, vineyard machinery, and compact tractors with diverse accessory attachments.
Forestry Equipment: Small timber cranes, wood processors, and tree grabbers requiring precise, individualized function pressures.
Municipal and Service Vehicles: Small tow trucks, truck-mounted salt spreaders, and mini-dumpers.
Industrial Power Units: Custom test benches and small automated factory machinery blocks.
SD5 valves are typically packaged securely to prevent damage during transit. The packaging includes:
Protective Wrapping: To safeguard the pump from environmental damage.
Custom Crates: For larger, heavier pumps, ensuring safe handling.
Documentation: Includes installation, maintenance instructions, and warranty details.
Delivery time depends on the model, customizations, and location but typically ranges from 2 to 6 weeks from the order date.
Parallel (Standard): Allows multiple spools to operate at the same time, but the oil goes to the path of least resistance.
Series: Oil from the return of the upstream spool feeds the inlet of the downstream spool, allowing simultaneous operation at proportional speeds.
Tandem: Gives strict priority to the upstream spool. Downstream spools only get oil flow when the upstream spool is completely in neutral.
Yes, we support OEM and customization, including nameplate, packaging, and specific performance requirements. Send us your drawings or specifications for evaluation.
SD5 Valve are manufactured in compliance with international standards, ensuring high performance and reliability:
ISO 9001: Certified for quality management systems.
CE Certification: Ensures compliance with European safety, health, and environmental protection standards.
RoHS Compliance: Ensures the pump does not contain hazardous materials.
Factory Testing: Every valve is rigorously tested for performance, pressure, and leak integrity before shipping.
