AI-Powered supplier vetting

SummaryNINGBO BOSHLE HYDRAULIC TECH CO., LTD. is identified as a China-based manufacturer/factory in Ningbo, Zhejiang, with business information also describing it as a trading company. Its stated product output is 500,000 hydraulic solenoid valves annually, with off-season lead times within 15 working days and peak-season fulfillment in one month. The supplier provides OEM and ODM services and can customize from samples, but reported no new products in the past year and no available SDK. Export activity spans 13 years, with exports representing 21%–30% of total sales and markets across multiple regions. Overseas service infrastructure is limited: no overseas showroom, agents, branches, or offline trade-show participation are reported. Quality-related procedures exist for supplier assessment, corrective/preventive action, and complaint handling, but written records are unavailable; raw-material traceability and quality assurance status are unknown. No certification information or customer cases are provided.

After-Sales capabilityThe supplier reports no overseas showroom, agents, branches, or overseas service countries. It has procedures for corrective/preventive actions and customer complaints, but no written records, which indicates documented service mechanisms are incomplete and international after-sales support is limited.

R&D capabilityThe supplier provides ODM services and sample-based customization, but it has no available SDK and launched no new products during the past year. These explicit limitations outweigh the available design-related service evidence for innovation assessment.

Production capacityStated annual output is 500,000 hydraulic solenoid valves, with lead times within 15 working days off-season and one month during peak season. The supplier also reports three qualified service-capability suppliers and broad export-market coverage, providing explicit evidence of established production and fulfillment capacity.

Customization capabilityThe supplier explicitly offers customization from samples and provides ODM services. These two stated capabilities directly support its ability to deliver customized hydraulic products.

Product Q&A

Q:What are the available configurations for this valve?

The valve is available with or without a drain port and with or without an unloading function. Type SV has no drain port, while Type SL includes a leakage port Y.

Q:How does the pre-opening feature work?

The pre-opening ball poppet valve (Type SV...A... and SL...A...) leaves the seat first when the control piston moves, allowing dampened decompression to avoid pressure shocks.

Q:What standards does the porting pattern comply with?

The porting pattern complies with DIN 24 340 Form A, ISO 5781, and CETOP-RP 121 H for sub-plate mounting.

Q:What materials are used for the valve body?

The standard material is Cast Iron. An optional Nodular Cast Iron (Qt500) is also available for customization.

Q:What is the minimum control pressure requirement?

A certain minimum control pressure is necessary at control port X to ensure the proper opening of the valve via the control piston.
