Blast Furnace Burner Valves

Valve Seat Cooling

The Yosmite Burner Valve features two integral water-cooled seats within the valve body. Cooling water enters the jackets and discharges through piping connections at the base. Constant venting at the top prevents air accumulation and provides a visual indication of cooling water flow.

Disc Seating

Ensuring accurate and positive seating of the disc is a priority. Both the disc and valve body have welded, polished stainless steel seats for positive shut-off. Externally adjustable eccentrics ensure precise disc positioning, preventing the disc from wiping the body seat, extending seat life.

Secure Stem-Disc Attachment

The disc is securely attached to the stem via a welded stainless steel adapter plate and stainless steel hexagon bolts. This robust and reliable connection ensures durability and effective operation, even under heavy-duty conditions, maintaining the valve's integrity and performance over time.

Flushing and Cleanout

The Yosmite Burner Valve includes an extra-large clean-out arrangement to isolate dirt and moisture entrainment from the blast furnace gas, protecting the valve seating surfaces from deterioration. Ample flush-out connections are provided for recommended periodic maintenance, ensuring optimal performance and longevity.

Quality and Testing

Each Yosmite Burner Valve is fully assembled and thoroughly tested before leaving the factory. Shipped ready for installation with lifting lugs for easy handling, the valve flanges are machined with holes for standard bolts, ensuring an airtight connection and reliable operation.

Yosmite Excellence

As with all Yosmite products, the burner valve is entirely designed and engineered by Yosmite, manufactured under strict quality control, and backed by efficient and reliable Yosmite service. This commitment ensures high-quality, dependable products that meet industry standards and customer needs.
