Key features

Water Hammer Elimination: Reduces impact caused by water hammer after fire pump shutdown in large water supply systems.

Self-Cleaning Screen: Inlet screen prevents large suspended particles from entering the control system for smooth operation.

Hydraulic Independent Operation: Driven by hydraulic pressure for independent, stable, and accurate control without external power.

Flexible & Serviceable Design: In-line serviceable for easy maintenance with flexible design allowing easy addition of features.

Pressure Relief & Maintenance: Instantly opens to relieve excess pressure and sustains upstream pressure to preset values.

Pump Protection: Prevents pump overload, cavitation, and limits flow by sustaining differential pressure.

Durable Cast Iron Construction: Made of DN125 PN16 ductile cast iron (GGG50) for high strength and long service life.

Space Saving Installation: Compact design saves installation space while ensuring high stability and accuracy.

AI-Powered supplier vetting

SummaryShanxi Midas Industrial Co., Ltd. is identified in the provided records as a China-based limited company and manufacturer/factory, although another record labels it as a trading company, creating a classification inconsistency. It offers ductile iron pipes and fittings, steel pipes and fittings, valves, manhole covers, couplings, flanges, water meters, dismantling joints, flange adaptors, and pumps. The supplier reports more than 10 production lines, ductile iron pipe output of 8,000 tons, broad export-market coverage, in-stock capability, and peak/off-season lead-time data that is inconsistently formatted. It provides multiple customization options, ODM services, and OEM services for popular brands, but reports no new products in the past year and no SDK. Significant control-system weaknesses are reported: no written corrective-action or complaint-handling procedures, unknown quality-assurance and traceability status, and zero quality-control testing equipment. No certification or customer-case evidence...

After-Sales capabilityThe supplier has in-stock capability and accepts multiple quotation and payment terms, but has no overseas warehouse, showroom, agent, or branch. It also reports no written procedures or records for handling customer complaints, indicating an explicitly weak documented after-sales process.

R&D capabilityThe supplier reports ODM service availability and multiple customization options, but states that it introduced no new products during the past year and has no available SDK. The evidence does not establish sustained product innovation.

Production capacityThe supplier reports more than 10 production lines, 8,000 tons of ductile iron pipe output, in-stock capability, broad product coverage, and exports to multiple regions. However, service-capability assessment lacks written procedures, and the stated peak/off-season lead times are inconsistently formatted, so operational reliability is only partially evidenced.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization, and also provides ODM and OEM services for popular brands. These statements directly support a broad customization capability.

Product Q&A

Q:What is the primary function of the 400X flow control valve?

It instantly opens when pipeline pressure exceeds the preset safe level to relieve excessive pressure, and closes slowly when pressure normalizes. It also maintains upstream pressure to a preset value.

Q:How does the valve protect against water hammer?

After the fire pump is shut down, the valve serves as a water hammer eliminating device in large water supply systems, reducing the impact caused by sudden pressure changes.

Q:What material is used for the valve body?

The valve is made of ductile cast iron GGG50 with a DN125 size and PN16 pressure rating.

Q:Does the valve require external power for operation?

No, it features hydraulic pressure-driven independent operation, ensuring high stability and accuracy without external power sources.

Q:How is the control system protected from debris?

It utilizes a self-cleaning screen at the inlet that prevents suspended particles of relatively big specific gravities and diameters from entering the control system.
