Buy & Import Cast steel gate valve from ZHEJIANG Kojo Valve Co., Ltd - Wholesale Supply

This cast steel gate valve is engineered to meet ANSI B16.34 and API 600 standards with a rising stem, bolted bonnet, and threaded or welded seat ring design. Available in pressure classes from 150 to 1500, it supports multiple material grades including ASTM A216 WCB, A217 WC6, and stainless steels such as A351 CF8 and CF8M. The inclusion of an anti-friction ball thrust bearing ensures low operating torque and extended valve life under frequent cycling.

The valve body and trim materials are selected based on service conditions: WCB for general service, WC6 for elevated temperatures, and CF8M for corrosive environments. Seat rings are either threaded or welded depending on maintenance requirements, and the flexible wedge provides tight shutoff under varying pressure differentials. Face-to-face dimensions comply with ANSI B16.10 and API 6D, ensuring interchangeability with existing pipeline systems.

These valves are commonly used in oil refineries, power plants, and chemical processing facilities where precise isolation and durability are critical. Packaging includes internal rust inhibitors, flange protection, and export-grade wooden crates. Trade terms are available under FOB and CIF, with lead times dependent on order size and material availability. Buyers should confirm material traceability and pressure testing documentation before shipment.

Frequently Asked Questions About Cast steel gate valve from ZHEJIANG Kojo Valve Co., Ltd
Available materials include ASTM A216 WCB for carbon steel, A217 WC6 for low-temperature service, and stainless grades A351 CF8, CF8M, CF3, CF3M, and CN7M. Each material has different corrosion resistance and temperature limits. Buyers must specify the exact grade and request a mill test report to confirm composition.

Sourcing Cast steel gate valve from ZHEJIANG Kojo Valve Co., Ltd - China Import Guide

Verify the material grade and certification for each valve component before accepting delivery. Request mill test reports for the body, stem, and seat materials, especially for stainless steel variants. Confirm that the pressure class matches your system’s maximum allowable working pressure. Do not rely on vendor claims without documented proof of compliance with ANSI B16.34 and API 600.

Lead time is not stated and may range from 4 to 12 weeks depending on material availability and order volume. Incoterms offered are FOB and CIF, but buyers must confirm the port of origin, destination, and insurance coverage. Payment terms are not listed; standard practice is 30% advance and 70% against BL copy. Confirm whether the supplier provides export documentation, including certificate of origin and packing list.

Upon receipt, inspect for flange damage, missing protective caps, and signs of corrosion. Test handwheel operation to ensure smooth movement without binding. Confirm the presence of the grub screw and lubrication points. Request a pressure test report conducted at 1.5 times the rated pressure. For critical applications, arrange for third-party inspection prior to shipment, focusing on weld integrity and seat leakage.
