Import Cast Iron Gate Valve — Buy in Bulk from Supplier in China

The Cast Iron Gate Valve supplied by Tonglu Wanhe Valves Product Co., Ltd. is a non-rising stem design intended for on-off control in pipelines carrying water, oil, and gas. It features a cast iron body conforming to ASTM A126 Class B material standards, with a pressure rating of PN10 and nominal diameters ranging from DN50 to DN300. The valve includes a bronze wedge and a resilient seat, ensuring tight shut-off under standard operating conditions.

Cast iron gate valves of this type typically use grey iron with a minimum tensile strength of 150 MPa and a carbon content between 2.5% and 3.5%. The internal surfaces are coated with epoxy resin to resist corrosion in wet environments, a common practice in industrial valve manufacturing. This variant does not include a rising stem, making it suitable for installations with limited vertical clearance. The design follows API 600 guidelines for gate valve construction, though no certification documents are provided by the supplier.

This valve is commonly purchased by water utilities, municipal treatment plants, and oilfield service contractors in Southeast Asia and the Middle East. Buyers typically order in quantities of 50 to 500 units per shipment. Packaging is in wooden crates with foam padding, and standard trade terms are FOB Hangzhou Port. Lead time is not stated; buyers must confirm delivery schedules directly with the supplier.
