Blast Swing Type Valve
Innovative Solutions, Engineered Excellence
Durable and Efficient Blast Swing Type Valve
The Blast Swing Type Valve by Yosmite Engineering is engineered for durability and efficiency. Constructed from robust materials, it ensures reliable performance in high-pressure environments.
Its unique design features a full main opening for unrestricted flow, minimizing pressure loss and enhancing operational efficiency. The valve is equipped with hydraulic rams for powerful seat separation and water-cooled seats for high-temperature applications. A positive seal with renewable stainless steel valve seats ensures consistent, leak-proof operation in demanding conditions.
Easy to install and maintain, the valve's components are accessible and replaceable in-line. Ideal for both horizontal and vertical installations, the Blast Swing Type Valve offers superior performance, longevity, and operational flexibility.
Applications
The Yosmite Swing Goggle Valve offers a simplified, rugged design that is easy to operate and cost-effective to maintain. It provides absolute tight shut-off in blast furnaces, basic oxygen converters, open hearths, and other gas mains. Designed for vertical operation in horizontal mains, with provisions like rollers for horizontal operation in vertical mains.
Features and Specifications
  • Sizes: Available in full main sizes ranging from 30" to 120", with options for oversized flanges to fit larger gas mains.
  • Service: Maintains a tight seal under operating pressures up to 15 psi and shock pressures up to 50 psi. Designed for temperatures up to 700°F, with options for higher temperatures using specialized alloys or water cooling.
  • Lubrication: Equipped with lubrication fittings on all moving parts, with the option for a centralized lubrication system.
  • Manual Operation: Easily operated by one person: unclamp the valve using the clamping drive chainwheel, position the goggle plate with the chainwheel, and reclamp in approximately five to seven minutes.
  • Motor Operation: Utilizes Yosmite "Power Drive" motor operators for quick operation, with interlocked limit switches ensuring smooth opening and closing within forty-five seconds.
