Direct Answer

Industrial gate valve price varies significantly by size, and a typical DN50 gate valve is much cheaper than a DN100 valve because material consumption, machining complexity, and pressure class requirements increase with diameter. In general, DN50 industrial gate valves are used for small to medium pipelines with lower cost entry, while DN100 valves are designed for higher flow capacity and heavier-duty industrial systems, resulting in a noticeably higher price per unit.

Industrial Gate Valve Price List per Size DN50 DN100 Overview

Industrial gate valve pricing is directly influenced by size, pressure rating, material grade, and API compliance standards. Therefore, DN50 and DN100 valves are not just scaled versions of each other—they represent different structural load requirements.

DN50 valves are commonly used in compact pipeline systems, utility lines, and secondary process control lines. In contrast, DN100 valves are widely deployed in main pipeline systems, chemical plants, and oil & gas distribution networks where higher flow capacity is required.

DN50 Industrial Gate Valve Price Factors

DN50 gate valves typically have lower manufacturing cost due to reduced material usage and simpler casting requirements.

Key pricing factors include:

• Smaller body size and lighter casting weight
• Lower machining time and reduced raw material cost
• Standard pressure class options (Class 150 / 300)
• Common carbon steel or stainless steel configurations

Because of these factors, DN50 valves are often the most cost-efficient entry-level industrial valve size for medium-duty systems.

DN100 Industrial Gate Valve Price Factors

DN100 gate valves require significantly more material and structural reinforcement, which directly increases cost.

Key pricing factors include:

• Heavier valve body and increased wall thickness
• Higher torque stem design and stronger sealing structure
• Greater compliance requirements for high-pressure systems
• More frequent use in API 600 / API 598 certified applications

Therefore, DN100 valves are typically selected for primary pipeline control where reliability and flow capacity are critical.

Material and Pressure Class Impact on Price

Beyond size, material selection plays a major role in industrial gate valve pricing.

Common materials include:

• Carbon steel (ASTM A216 WCB) → cost-effective for standard service
• Stainless steel (316 / 321 / 310S) → higher corrosion resistance, higher cost
• Duplex stainless steel (2205) → high strength + chemical resistance, premium pricing

Higher pressure classes (Class 600 and above) also significantly increase cost due to thicker walls and stricter testing requirements.

Industrial Gate Valve Price List Summary Insight

In real industrial procurement, DN50 valves are typically used for auxiliary or branch pipelines, while DN100 valves are selected for core process pipelines. As a result, DN100 valves often cost 1.5x–3x more depending on material and pressure rating.

Frequently Asked Questions (FAQ)

Q1: Why is DN100 industrial gate valve more expensive than DN50?

DN100 valves require more raw material, thicker pressure-bearing walls, and higher machining precision. Therefore, manufacturing cost and final pricing are significantly higher.

Q2: Does pressure class affect DN50 and DN100 gate valve price?

Yes. Higher pressure classes such as Class 600 or Class 1500 require stronger bodies, better sealing surfaces, and more rigorous testing, which increases cost for both DN50 and DN100 valves.

Q3: Which is more cost-effective for industrial use, DN50 or DN100 gate valve?

DN50 is more cost-effective for small pipelines, but DN100 offers better long-term efficiency for main flow systems where higher capacity is required.
