High Temperature Resistant Stainless Steel Butterfly Valve DN50 Price, Working Condition up to 500°C
I. Price Range Reference
Currently, the price of a high temperature resistant stainless steel butterfly valve DN50 suitable for 500°C working conditions is roughly as follows:
Economy Grade (200–500 RMB): Made of ordinary heat-resistant stainless steel (e.g., 304). Suitable for stable temperatures with infrequent switching.
Standard Grade (500–1200 RMB): Made of heat-resistant steel or 316L material, equipped with high-temperature resistant seals (e.g., graphite). Suitable for continuous 500°C operation.
Premium Grade (1200–2500 RMB): Made of special high-temperature alloy steel, featuring cooling fins, fire-safe and explosion-proof design. Suitable for severe high-temperature conditions.
Note: Pneumatic or electric actuators require an additional 800–3000 RMB.The main Butterfly Valve product names of China Butterfly Valve Network include:High Temperature Butterfly Valve,Flange Metal Sealed Swing Butterfly Valve,Electric Metal Hard-sealed Wafer Butterfly Valve,

II. Factors Affecting Price
Material: Advanced heat-resistant alloys (e.g., 310S, Inconel) have higher prices.
Seal Type: High-temperature graphite seals are 30%–50% more expensive than PTFE seals.
Actuation Type: Manual is the cheapest; pneumatic/electric significantly increase cost.
Brand & Certification: Products with TS or SIL certification command higher prices.
III. Purchasing Suggestions
Clearly define your operating conditions: specify the medium, maximum temperature, pressure, and switching frequency.
Don’t just look for the lowest price – under 500°C conditions, a low-quality butterfly valve will quickly deform and fail.
Request high-temperature test reports or case studies.
For a precise quotation, we recommend requesting quotes from 2–3 professional valve manufacturers and providing detailed operating parameters.
