Integrated Pump Protection: Combines flow sensing, recirculation control, depressurization, and check valve functions in one unit.
High Pressure Resistance: Supports high differential pressure up to 30 MPa with integrated multi-stage throttle relief.
Anti-Cavitation Design: M-type multi-stage bypass reduces noise and prevents cavitation damage to valve components.
Automatic Flow Control: Automatically opens bypass when main flow drops below preset minimum to protect pump from cavitation.
Wide Pressure Range: Pressure rating PN16-PN420, suitable for high-pressure industrial applications.
Robust Material Options: Forged steel body with options for WCB, WC6, WC9, and various stainless steels.
Noise Reduction: Multi-stage pressure-reducing design minimizes noise generated by high-speed flowing media.
Versatile Application: Ideal for centrifugal pumps conveying hot water or steam, preventing instability during low load.

AI-Powered supplier vetting
SummaryThe supplier manufactures specialized equipment for oil refining and chemical production and also conducts hardware product manufacturing, research and development, sales, and related services. It reports ISO 9001 and ISO 14001 certification, two production lines, six to ten quality-control staff, and six to ten years of total R&D engineer experience. The supplier offers broad customization, OEM, and ODM services, with documented inspection, corrective-action, complaint-handling, and traceability procedures. Export experience is stated as 15 years, with 51%–70% of total sales from exports and self-operated import/export rights. However, it has no overseas agents or branches, warehouses, showrooms, or SDK availability; it also reports no new products in the past year and no valid manufacturing-capacity contract with related subcontractors. Customer cases are not specifically provided.
Supplier typeThe stated business scope includes manufacturing and sales of specialized equipment for oil refining and chemical production, hardware product manufacturing, hardware R&D, and ferrous metal casting. The company description also covers material purchasing, production, inspection, delivery, and after-sales service, indicating a manufacturer with integrated related operations.
CertificationsThe supplier reports holding ISO 9001 and ISO 14001 certifications. These are explicit certifications relevant to quality and environmental management systems.
After-Sales capabilityThe supplier states that its operations include after-sales service and has clear, followed procedures and records for handling customer complaints and corrective and preventive actions. However, it reports no overseas agents or branches and offers overseas services in zero countries, which limits directly evidenced overseas service coverage.
Production capacityThe supplier operates two production lines, maintains six to ten quality-control staff, has in-stock service capacity, and uses documented inspection, supplier assessment, corrective-action, complaint-handling, quality-assurance, and material-traceability procedures. Nevertheless, it reports no valid contract with associated subcontractors for manufacturing capacity, creating a documented weakness in subcontracting governance.
Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization. It also provides OEM services for well-known brands and ODM services, demonstrating broad stated customization and manufacturing-design support.
Product Q&A
Q:What is the primary function of the ZDM Automatic Return Three Way Valve?
A:
It is a pump protection device that automatically protects centrifugal pumps from cavitation damage and instability during low load operation by maintaining minimum flow.
Q:How does the valve handle high differential pressure?
A:
It features an integrated multi-stage throttle relief valve in the bypass that reduces pressure and handles differential pressures up to 30 MPa.
Q:What materials are available for the valve body?
A:
The valve body is forged steel, with options including WCB, WC6, WC9, 12crmo, 12crmov, 15CrMo, and 15crmov.
Q:Does the valve prevent backflow into the pump?
A:
Yes, it includes a standard bypass with a check function to prevent liquid from flowing back into the pump body.
Q:What is the nominal diameter range for this valve?
A:
The nominal diameter ranges from DN40 to DN500.
