AI-Powered supplier vetting

SummaryThe supplier offers OEM services for well-known brands and has strong customization capabilities, including ODM services. However, it lacks a software development kit (SDK) for R&D, certification for supplier management systems, and overseas service facilities. While there's evidence of financial stability and ability to conduct fire drills, the company does not have documented procedures for supplier service capability. Production is robust with advanced equipment and quality control processes in place, but export sales are minimal. The company has a clear procedure for handling customer complaints.

Supplier typeThe supplier provides OEM services for well-known brands and operates in industries like industrial applications, mobile machinery, and water conservancy engineering.

CertificationsThe supplier lacks certifications for supplier management systems.

Financial creditThe supplier shows financial stability over the past three years, as indicated by consistent cash flow and profit indices.

R&D capabilityThe supplier provides ODM services and has introduced new products in the last year, but lacks an SDK for R&D.

Production capacityThe supplier has significant production capabilities with modern equipment, producing a wide range of hydraulic cylinders daily.

Customization capabilityThe supplier offers extensive customization services, including full and flexible customization options.

Client casesThe supplier does not have overseas showrooms, agents, or branches, limiting its international reach.

Product Q&A

Q:How does the 4WEH electro-hydraulic directional valve work?

The electromagnetic pilot valve switches position upon receiving an electrical signal, changing control oil flow direction. This pushes the main valve core to move, achieving directional change. When powered off, the reset spring returns the main valve to its initial position.

Q:What are the installation precautions for the WEH valve?

Ensure the installation surface is clean and free of impurities. Tighten bolts evenly to prevent leakage. Connect oil ports correctly to avoid reverse connection. Avoid high temperature, humidity, or corrosive environments. Follow design requirements for installation direction.

Q:What causes unstable direction during operation?

Causes include unstable control oil pressure, pilot valve malfunction (insufficient suction or stuck core), main valve core sticking, damaged reset springs, or severe oil contamination with impurities affecting valve core movement.

Q:What are the maximum flow rates for different sizes?

The maximum flow rate is generally 300L/min for diameter 16, 650L/min for diameter 25, and around 1100L/min for diameter 32.

Q:Is customization available for this valve?

Yes, we offer full customization, customization from samples, customization from designs, flexible customization, and minor customization options.
