Import Check Valve — Buy in Bulk from Supplier in China

Hydera Machinery Limited supplies a check valve that is cast iron or ductile iron based. The valve is offered in flanged and wafer designs, each supporting single‑door or dual‑plate configurations. Its lightweight construction eases installation and maintenance in plant pipelines. The product conforms to recognised international standards for backflow prevention.

Cast iron provides high strength and wear resistance, while ductile iron adds flexibility under pressure spikes, a combination common for industrial fluid control. Typical industry grades for such valves are ASTM A536 for ductile iron and ASTM A48 for cast iron. The designs meet standard pressure classes up to 250 bar, suitable for demanding environments. The valve’s dimensions follow standard flange sizes from DN 50 to DN 200, facilitating integration with existing systems.

Primary users include water‑treatment facilities, oil‑and‑gas processing plants and general manufacturing lines where backflow protection is critical. Trade terms are flexible, with FOB or CIF shipping available, but buyers should confirm the exact incoterm and payment method with the supplier. Minimum order quantities are negotiable; request a quotation to establish the batch size. Inspection can be arranged under ISO‑based protocols prior to shipment.
