‌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 feature high pressure resistance and excellent sealing properties, suitable for pipeline systems handling various high-pressure, high-temperature, and corrosive media.

Material and Standards

The Russian standard gate valves are available in various materials, including cast iron and stainless steel. For instance, components such as the valve body, cover, and bracket are often made of materials like WCB, A105, and Cr5Mo, while the gate plate and valve stem are commonly made of materials such as 25Cr2MoV and 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 types, with the most common being wedge gate valves and parallel gate valves. Their sealing surfaces can be self-sealed by the medium pressure, which means the gate plate is pressed against the valve seat by the medium pressure to achieve sealing. This design allows the Russian standard gate valves to perform exceptionally well when not frequently opened or closed, and when kept fully open or fully closed. However, they are not suitable for high-speed flowing media or situations requiring flow regulation, as partial opening may cause vibration and wear.

Performance Parameters & 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 enable long-term stable operation in harsh environments of these industries. Moreover, Russian standard gate valves offer advantages like low flow resistance and easy operation, making them suitable for pipeline systems handling various high-pressure, high-temperature, and corrosive media.
