DIN 3352 F4 Gate Valve, GS-C25, DN400, PN16, Rising Stem, RF

Key Specifications / Features

The China DIN 3352 F4 Gate Valve Plant offers a robust solution for industrial fluid control. This gate valve features a cast carbon steel GS-C25 body, ensuring durability and reliability. With a DN400 (16-inch) size and a PN16 (Class 150 LB) pressure rating, it is designed to handle high-pressure applications. The rising stem design provides easy operation and monitoring, while the RF flanged ends ensure secure connections. Handwheel operation makes it user-friendly, making it ideal for various industrial settings.

Wedge Gate Valves are meticulously designed and manufactured to ensure that the leakage of volatile organic compounds (VOCs) is kept to less than 100 parts per million (ppm). To achieve this, extensive baseline laboratory testing, encompassing both static and cycle testing, has been conducted. This testing has established the critical design parameters needed to achieve low-emission sealing in both the stem packing seal area and the bonnet gasket sealing area. Furthermore, an in-house testing procedure has been developed and is periodically performed. This ensures that the standard product design and manufacturing criteria consistently result in Wedge Gate Valves meeting a maximum VOC leakage of 100 ppm before shipment.
