Stainless Steel Gate Valves 30нж41нж

DIYE VALVE stainless steel gate valves 30нж41нж are flanged gate valves specifically designed for the demanding requirements of the Russian and CIS markets. Every dimension of the product, including flange bore (compliant with GOST 12815), face distance (compliant with GOST 3706), and pressure rating (Py16 to Py100), is precision-machined according to strict Russian standards, allowing for direct, unmodified installation into standard Russian piping systems. The valve body is precision-cast from high-grade stainless steel such as 304, 316, 321, and 316Ti, ensuring excellent corrosion resistance and structural integrity under extreme conditions.

Core Performance and Design Features

1.Superior Material

Utilizing high-grade stainless steel such as 304, 316, 321, and 316Ti, these valves offer excellent rust resistance, chemical corrosion resistance, and oxidation resistance, making them ideal for acid, alkali, and high-temperature media applications.

2.Strict GOST Compliance

Fully compliant with GOST 5762 (design), GOST 9698 (materials), and GOST 12815 (flanges) standards, ensuring 100% compatibility with CIS pipeline systems.

3.Low Flow Resistance Design

Optimized full-bore design minimizes pressure loss, ensuring efficient and smooth fluid transmission in large-diameter pipelines.

4.Multiple Actuation Methods

Stainless steel gate valves 30нж41нж support multiple actuators including manual (handwheel), bevel gear, electric, and pneumatic, adapting to both automated and manual control systems.

5.Wide Pressure and Temperature Range

Rated pressures cover Py16 to Py100, maintaining reliable sealing performance under complex thermal and hydraulic loads.
