Back Pressure Valve
The Back Pressure Valve from Shanghai Topkun Machinery Co.,Ltd is designed to enhance chemical dosing system performance, with adjustable pressure control from 10Kpa to 31.5Mpa. It supports corrosive liquids and air, featuring diaphragm options in PTFE or EPDM for chemical compatibility. Connection types include thread or flange, customizable to system requirements.
Material construction spans PVC, PVDF, carbon steel, SS304, and SS316L, each selected for resistance to specific media. Diaphragm choice aligns with the fluid’s chemical properties: PTFE for aggressive acids and solvents, EPDM for water-based or mild chemical applications. The valve’s modular design allows for quick diaphragm replacement, reducing downtime in industrial settings.
These valves are used in chemical processing, water treatment, and pharmaceutical manufacturing where precise backpressure is critical. Buyers typically integrate them into dosing pumps or metering systems to stabilize flow and prevent siphoning. Sourcing terms, including MOQ and lead time, are confirmed directly with the supplier, as these details are not specified in the listing.

Sourcing Back Pressure Valve from Shanghai Topkun Machinery Co.,Ltd - China Import Guide
Before ordering, verify the exact pressure range and material compatibility for your application. Confirm whether the valve’s diaphragm and body materials are rated for the media’s chemical properties, temperature, and concentration. Request material test certificates and pressure test reports to ensure compliance with your system requirements.
Discuss logistics and lead times directly with Shanghai Topkun Machinery Co.,Ltd. Clarify Incoterms such as FOB Shanghai or CIF destination port, and confirm packaging standards for export. Lead times for custom configurations may exceed standard inventory items, so plan procurement accordingly.
Conduct quality checks upon receipt, focusing on diaphragm integrity and pressure settings. Inspect for damage during transit and test the valve under controlled conditions before installation. Ensure documentation, such as material certificates and test reports, accompanies the shipment for traceability.
