Import F4 F5 Resilient Gate Valve — Buy in Bulk from Supplier in China

The F4 F5 resilient gate valve from Qixiang Valve Industry Co. is a cast ductile iron valve designed for bidirectional flow control in pressurised fluid systems. It meets DIN 3352 for design and DIN 3202 for face-to-face dimensions, with flange standards conforming to EN 1092-2. The valve body is made from GGG5 ductile iron, rated for pressures up to PN16 and operating temperatures between -10°C and 80°C. Its resilient seat is constructed from EPDM rubber, providing a bubble-tight shut-off under low to medium pressure conditions.

This valve type is standard in water distribution, wastewater treatment, and industrial process lines where frequent cycling and leak prevention are critical. The EPDM seat offers resistance to chlorinated water and mild chemical exposure, making it suitable for municipal and industrial applications. The disc and stem are typically coated with chrome plating or stainless steel to resist corrosion, though exact plating thickness is not specified in the listing. Typical industry alternatives include rubber-seated gate valves with NBR or FPM seats for higher temperature or chemical resistance.

Buyers in municipal water authorities, wastewater treatment plants, and industrial maintenance departments commonly source this valve for pipeline infrastructure upgrades. Packaging is usually in wooden crates with protective end caps, and bulk orders are shipped via container. Minimum order quantities and lead times are not stated and must be confirmed directly with the supplier. Payment terms may include T/T or L/C, but these are subject to supplier agreement.

Qixiang Valve Industry Co. is based in Dongying, Shandong Province, China, with a registered address at No.1 Kaifa Road. The supplier is classified as an imported-tier vendor with harbor trust verification, indicating compliance with export documentation standards. The listing confirms no manufacturing history, workforce size, or client references. Response metrics show no recorded activity, suggesting limited buyer engagement or inactive communication channels.

The company appears to operate as a manufacturer or exporter of industrial valves, with this listing representing one product line. There is no mention of internal quality control systems, certifications such as ISO 9001, or third-party testing. The absence of response rate data and verified production capacity means buyers should request production timelines and inspection reports prior to order placement.
