Russian Standard Gate Valves refer to gate valve products that comply with Russian national standards. These valves are strictly manufactured in accordance with Russian relevant standards to ensure product quality and performance. Russian Standard Gate Valves typically offer high pressure resistance and excellent sealing properties, suitable for pipeline systems handling various high-pressure, high-temperature, and corrosive media.

Material and Standards

The material of Russian standard gate valves is diverse, including cast iron, stainless steel, etc. For instance, components such as the valve body, cover, and bracket are often made of materials like WCB, A105, Cr5Mo, while the gate plate and valve rod commonly use materials like 25Cr2MoV, 1Cr18Ni9Ti. The selection of these materials ensures the stability and durability of the gate valves in harsh environments.

Structural Form and Application Scenarios

The Russian standard gate valves come in various structural forms, with the most common being wedge gate valves and parallel gate valves. Their sealing surfaces can be self-sealed by the medium pressure, meaning the gate plate is pressed against the valve seat by the medium pressure to achieve sealing. This design allows Russian standard gate valves to perform exceptionally well under conditions where they do not need to be frequently opened or closed, and when they are kept fully open or fully closed. However, they are not suitable for use with high-speed flowing media or in situations requiring flow regulation, as partial opening may cause vibration and wear.

Performance Parameters and Application Fields

Russian standard gate valves are widely used in pipeline systems across industries such as oil, chemical, power, and metallurgy. Their excellent corrosion resistance and high strength allow for long-term stable operation in harsh conditions within these industries. Moreover, Russian standard gate valves offer benefits such as low flow resistance and ease of operation, making them suitable for pipeline systems handling various high-pressure, high-temperature, and corrosive media.
