2026 Price Reference for DN50 304 Rising Stem Gate Valve

DN50 304 stainless steel rising stem gate valve prices vary based on connection type, pressure rating, and configuration:

Flanged connection DN50 304 stainless steel gate valves with PN16 rating typically range based on configuration and certification requirements.

Threaded connection DN50 304 stainless steel gate valves for smaller or lower pressure applications are generally priced lower than flanged equivalents.

Premium models with 316L stainless steel, higher pressure ratings, and comprehensive documentation packages command higher pricing.

Key factors affecting price include connection type (flanged vs threaded), pressure rating (PN16 vs PN25), body material (CF8 vs CF8M), and certification requirements.

Understanding Rising Stem Gate Valve Design

A rising stem gate valve features a stem that moves upward as the valve opens, providing a clear visual indication of the valve position. The DN50 valve has a 2-inch nominal bore suitable for many industrial flow control applications. The valve body is cast from CF8 (equivalent to 304 stainless steel), providing excellent corrosion resistance for a wide range of media. The wedge-type gate is guided by body guides to ensure proper seating and reliable shutoff.

The rising stem design allows for visual position indication even from a distance. This is particularly useful for applications requiring quick verification of valve status. The stem is typically made of 2Cr13 or 304 stainless steel for corrosion resistance and wear resistance.

Technical Specifications

Material: Valve body is cast CF8 (304 stainless steel) with excellent corrosion resistance for water, oil, gas, and mild chemicals. Stem is 2Cr13 or 304 stainless steel. Wedge and seat rings are hard-faced for wear resistance.

Pressure and Temperature: PN16 rating (1.6MPa) with temperature capability up to 200 degrees Celsius. Higher pressure ratings available on request.

Connections: Flanged connections per GB/T 9113, ANSI, or DIN standards are available. Threaded connections (NPT or G) are offered for smaller sizes.

Design Features: Rising stem provides visual position indication. Flexible wedge design accommodates thermal expansion. Bolted bonnet with spiral wound gasket for reliable sealing.

Standards: GB/T 12234 or API 600 for design and manufacturing. GB/T 12220 for general valve requirements. ISO 5208 for pressure testing.

Applications

DN50 rising stem gate valves serve critical functions in water supply and distribution, oil and gas pipelines, chemical processing, steam and condensate systems, and general industrial piping.

Selection Considerations

When selecting a DN50 304 rising stem gate valve, verify pressure rating exceeds maximum system operating pressure. Confirm material compatibility with your process media. For more corrosive media, consider 316L stainless steel. Choose connection type matching your piping configuration. Verify flange standard matches your piping (GB, ANSI, DIN).

Summary

Stainless Steel 304 Rising Stem Gate Valve DN50 is a reliable and durable industrial valve for shut-off applications. Selection requires careful evaluation of connection type, pressure rating, and material compatibility. The rising stem design provides clear visual position indication for easy operation verification. Consulting with qualified valve manufacturers is recommended to ensure proper valve selection and reliable long-term operation.
